CSERNI Gábor, BORI Rita, BOROSS Gábor, FRANK Emil, LÓRÁND Katalin, SERÉNYI Péter, LENGYEL Mária, KOVÁCS Károly, HALÁSZ Mátyás

[INTRODUCTION - The mortality of lung cancer is high, but with early diagnosis the disease can often be cured. The differential diagnosis of pulmonary carcinoma is widely diverse. CASE REPORT - In a 53-year-old male patient, who had been successfully treated for pneumonia complicated with thoracic empyema, both a CT scan and bronchoscopy raised the suspicion of a malignant tumour. Brush cytology was inconclusive; it raised the possibility of malignancy but was not felt diagnostic of a malignant process, whereas biopsy revealed only inflammatory changes. After right lower lobectomy, actinomycosis was diagnosed by histology. This case is used in the paper as an opportunity to discuss the pseudotumorous presentation of thoracic actinomycosis. CONCLUSION - Pulmonary and thoracic actinomycosis is rare, but due to its ability to simulate tumours, it is an important disease to consider in the differential diagnosis of lung cancer.]

[Introductions - The optimal therapy of brain stem tumours of different histopathology determines the expected length of survival. Authors report 125Iodine interstitial irradiation of brain stem tumours with stereotactic brachytherapy. Case reports - Two patients having brain stem tumours were suffering from glioma or from metastases of a carcinoma. In Case 1 the tumour volume was 1.98 cm3 at the time of planning interstitial irradiation. The control MRI examination performed at 42 months post-op showed a postirradiation cyst size of 5.73 cm3 indicating 65.5% shrinkage. In Case 2 the shrinkage was more apparent as the tumour vo-lume measured on the control MRI at 8 moths post-op was only 0.16 cm3 indicating 97.4% shrinkage of the 6.05 cm3 target volume at the time of brachytherapy with the metastasis practically disappearing. Quick access to histopathological results of the stereotactic intraoperative biopsy made it possible to carry out the 125Iodine stereotactic brachytherapy immediately after the biopsy, resulting in less inconvience for patients of a second possible intervention. The control MRI scans show significant shrinkage of tumours in both patients. Conclusion - The procedure can be performed as a biopsy. The CT and image fusion guided 125Iodine stereotactic brachytherapy can be well planned dosimetrically and is surgically precise.]

[INTRODUCTION - Authors present six cases of intramural oesophageal metastases of adenocarcinomas located in the gastro-oesophageal junction. The tumours and metastases were diagnosed by endoscopic examinations. PATIENTS AND METHODS - Between 01. 01. 1994. and 31. 12. 2000. a total number of 143 patients were examined with the diagnosis of adenocarcinoma of the gastro-oesophageal junction. In six patients (4,19 %), intramural oesophageal metastases were verified. In each case the diagnosis was confirmed by histological examination. TNM stage of the tumours was assessed considering the results of endoscopic ultrasound examination, the findings at initial operation and the pathological data in all cases, where resection was performed. The tumours were localized according to Siewert- Stein’s classification. RESULTS - In six patients who had adenocarcinoma of the gastro-oesophageal junction, the diagnosis of intramural oesophageal metastases was confirmed. The histological structure of the primaer tumours and metastases were the same. Metastases were detected by endoscopic ultrasound examination in three cases of the four examined patients as submucosal masses. All of the cardiac tumours proved to be well advanced: four of them classified as T4N1 by endoscopic ultrasound. Intramural metastases were diagnosed in each Siewert-Stein subgroups. CONCLUSION - Endoscopic examination is of crucial importance in the diagnosis of adenocarcinomas of the gastro-oesophageal junction and in their intramural metastases as well. Beside the endoscopic identification the primary tumour, the thorough examination of the proximal part of the oesophagus seems to be of great importance. These metastatic cancers appeared in the advanced stage of the disease. Endoscopic ultrasound examination is of great help in these cases to identify whether the mass causing oesophageal impression is outside of the wall of the organ, or in which layer it is localized. Endoscopic ultrasound examination also gives the possibility for preoperative assessment of the TNM stage of the disease.]

CSERNI Gábor, VÁGÓ Tibor, TÖRÖK Norbert, GAÁL Zoltán, VELKEI Tamás, SERÉNYI Péter, GÖCZŐ Katalin, TUSA Magdolna, KOVÁCS Katalin, SZŰCS Miklós

[INTRODUCTION - Carcinomatous meningitis is a serious complication of advanced stage solid tumours, which may become more common with improved survival. CASE REPORTS - A 53-year-old woman with a recent history of breast cancer (pT2pN2M0) had been treated by mastectomy and adjuvant chemotherapy and radiotherapy. She presented with weakness, diplopia and vertigo raising the possibility of vertebrobasilar ischaemia or an intracranial mass. In another patient, a 62-year-old man with hypertension, a stenotic common bile duct had been diagnosed when examined for abdominal complaints. When he presented with a high blood pressure value accompanied by intensive headache, vomiting and bilateral hearing loss, he was thought to have a hypertensive crisis. The rapidly progressive neurological symptoms and the history of breast cancer and findings suggesting pancreatic head tumour, respectively, led to the clinical diagnosis of carcinomatous meningitis in both cases, despite any evidence on CT scans or a negative MR scan, though of limited value, in the first case. This diagnosis was confirmed by the laboratory and cytological findings of the cerebrospinal fluid, and also by the post mortem examination, since both patients died within a month after the onset of the symptoms. The primary tumour in the second patient proved to be a widely metastasizing diffuse type gastric cancer. CONCLUSION - Carcinomatous meningitis has a varying but characteristic presentation which generally makes it easy to diagnose, but it can sometimes present differential diagnostic problems. What we can learn from these two cases may help in recognizing this complication.]

[125I brachytherapy of pineal parenchymal tumours]

JULOW Jenő, VIOLA Árpád, MAJOR Tibor, VALÁLIK István, SÁGI Sarolta, MANGEL László, KOVÁCS Rita Beáta, HÁVEL János, KISS Tibor

[Introduction - Pineal parenchymal tumours make up 0,3% of all brain tumours. Stereotactic biopsy has by now become an indispensable method to detect these tumours and it can be safely performed. Patients and method - Two patients with pineoblastoma were treated with 125I brachytherapy. The MRI and CT images taken 15 and 18 months after irradiation showed significant tumour shrinkage. Results - Tumour volume was 0.76 cm3 in the control CT image in Case 1, a shrinkage by 73% compared to 2.87 cm3 measured at the time of planning the interstitial irradiation. In Case 2, tumour volume measured on the control MRI examination was 0.29 cm3 as opposed to 1.27 cm3 of original tumour volume, which represents a 77% shrinkage. Conclusion - The insertion of isotope seeds was performed at the same time as the biopsy, because thus the knowledge of the histological diagnosis could spare the patients from a second stereotactic intervention. The CT- and image fusion guided 125I stereotactical brachytherapy is a procedure that can be dosimetrically precisely planned and surgically accurately and safely performed.]

[Tumour therapy with the tools of interventional radiology]

ENGLONER László

[The author reviews the interventional radiological methods applicable in tumour therapy. The therapy of non-resectable primary and secondary liver tumours is discussed based on literature data and own experience. The possibilities of percutaneous tumour ablation are limited by the size and number of the tumours. Intra-arterial chemotherapy, chemoembolisation and feeding artery occlusion can be successful resulting in longer life and better quality of life in cases with advanced tumours. The results are better if these methods are combined with systemic chemotherapy.]

[Cervical space occupying lesions: diagnosis at sonoelastography]

UJLAKI Mátyás, MAGYAR Péter, KARLINGER Kinga

[Among cervical (neck) region tumours, the thyroid lesions and the metastatic lymph nodes are the most detectable with conventional B-mode ultrasonography (US). The use of MRI and CT scans are limited because of the cost, and in case of CT, the radiation. With the introduction and constant development of sonoelastography, we have in our hands a new imaging procedure which is cheap, fast and harmless, yet giving more information to the examiner than conventional US. The elastographic examination of thyroid lesions is a more explored area than the elastographic visualisation of cervical lymph nodes. The ‘off-line’ elastography showed the highest accuracy allowing to calculate and analyse the strain index of cervical lymph nodes - strain index > 1.5 (85% sensitivity, 98% specificity) - but the ‘off-line’ processing of US elastograms is still too time consuming to be used in busy clinical settings. During the examinations of the thyroid gland both real-time and off-line processed strain imaging were used. An Italian team made a great leap forward as they standardized the degree of distorsion under the application of the external force. Then using the Ueno and Itoh elasticity score they achieved remarkable accuracy with real-time sonoelastography (P <0.0001). On the other hand only those organs are suitable for the US elastography characterization which can be slightly compressed, consequently the examination of a lesion with calcified shell cannot give useful information. Near to the pulsating arteries substantial amounts of decorrelation noise may appear and the examiner has to pay attention what structures are in the ROI box since the sonoelastography method assumes computations relative to the average strain inside the box. To detect a follicular carcinoma in the thyroid gland remains a big challenge. Despite of the limitations most researchers agree on the fact that sonoelastography is a perfect tool to use in addition to the conventional US examination. B-mode US combined with sonoelastography raised the accuracy in differentiation in all cases. With this modality it is also possible to deduce the number of cases when healthy lymph nodes or tissue peaces are taken for biopsy during FNAB.]

[SIMULTANEOUS PRESENCE OF GIST AND MALT-LYMPHOMA OF THE STOMACH IN A HELICOBACTER PYLORI NEGATIVE PATIENT]

KOVÁCS Ferenc, GYÖKERES Tibor, TAKÁCS Imre Géza, PADÁNYI István, FEKETE Csaba, OROSZ Zsolt, PAP Ákos

[INTRODUCTION - The simultaneous presence of gastric mucosa-associated lymphoid tissue lymphoma (MALT) and a gastrointestinal stromal tumor (GIST) is an extremely rare finding that has not been published until now. CASE REPORT - The authors report on a 78- year-old man who was referred to their department with an emergency upper gastrointestinal bleeding. Urgent gastroscopy revealed a bleeding ulcer in the middle third of the stomach. On the follow-up endoscopy 6 weeks later, an umbilicated polypoid lesion was found proximal to the healed ulcer, which was subsequently removed by elective surgery. Histology and immunohistochemical staining of the specimen for c-Kit confirmed the diagnosis of gastrointestinal stromal tumour. A few weeks later the patient was readmitted because of haematemesis. Upon detailed histological examination of the biopsy specimens taken from the multiple superficial ulcers found near the previous lesion, MALT-lymphoma was diagnosed. The absence of Helicobacter pylori was confirmed by repeated histological examinations, serology and urea breath test. CONCLUSION - This is the first report on a patient with simultaneous presence of a gastrointestinal stromal tumour and gastric mucosaassociated lymphoid tissue lymphoma with H. pylori negativity. Several observations suggest that the development of malignant tumours of the stomach is also associated with H. pylori infection. In view of the reported case, the possibility of a common aetiology of these two neoplasms other than H. pylori infection is discussed.]

[TNF-α blocking therapy in rheumatoid arthritis]

TAMÁSI László

[The research of pathomechanism of rheumatoid arthritis resulted in remarkable pragmatic results beyond the important theoretical knowledge. These observations led to the development of new effective agents, which were named as biological therapy and introduced in clinical praxis. The key factor of pathomechanism of rheumatoid arthritis is the proinflammatoric citokin TNF-α. It can be found on the top of the inflammation cascade where regulates many other inflammatory mediators and also plays an important role in the defence against infections and tumours. The author describes the TNF-α blocking agents used in clinical practice, their chemical and pharmacological feature, as well as their mode of action and the consequence of inhibition of TNF-α. He reviews the main results of the major clinical tests with infliximab, etanercet, and adalimumab. The results of these clinical studies demonstrate that the TNF-α blocking therapy gives clinical improvement in case of therapy resistant patients, decreases the number of swollen and tender joints, the pain, ESR and CRP, decreases the radiological progression, furthermore improves the quality of life. There are also some data about the favourable impacts observed during the early arthritis treatment. The TNF-α blocking therapy can be used effectively and safely in rheumatoid arthritis. In most cases the infusion reaction and the injection site reaction are not reasons for withdrawal from the study. The sideeffects, however, developed in increasing numbers during widespread applications. Among these the most important ones are the opportunist infection and the tuberculosis. In addition the sporadic occurrence of lupus-like symptoms, demyelinating disease, and aplastic anemia were reported. The fundamental requirements of the safety of the biological therapy are the professional indication and the careful monitoring during the treatment, the principle of which has been already prepared by the Professional College of the Rheumatology and Physiotherapy based on the international experience.]

[Removal of multiple thoracic dumbbell tumours through combined hemi-semi laminectomy and minimal invasive paraspinal approach]

PAPP Zoltán

[One third of the primary spinal tumours are neurinomas. These tumours most often located intraduralyextramedullary, but 15-25 percent of the cases, the tumour extends to the paraspinal region through the neuroforamina. Spinal manifestation of Schwann-cell tumours, usually neurofibromas, can be seen in neurofibromatosis. 31 years old female patient, suffering from NF1 was operated on with a Th 3-6 and Th 10-11 dumbbell tumours. At the first step the tumour mass, located in the spinal canal, was resected through a partial hemilaminectomy. At the second operation the extraspinal tumour was resected through a minimal invasive paraspinal approach. The author present the combined use of minimal invasive spine surgical technics and discuss the benefits and disadvantages of these approaches, compared to the standard surgical procedures.]
