[Initial experiences with TOF MR and contrastenhanced MR angiography of the supraaortic arteries]

TASNÁDI Tünde, KARDOS Klára

[INTRODUCTION - 95 MR angiographic examinations of the supraortic arteries were performed at the Rethy Pal Hospital, Bekescsaba between February 2003 and May 2005. The aim of this publication is to analyse the clinical benefit of contrast-enhanced MR angiography compared to duplex ultrasound and to evaluate the role of TOF MR angiography in the diagnostics of the carotid arteries. We compared the results of contrast-enhanced MR angiography, TOF MR angiography and duplex ultrasound. MATERIAL AND METHOD - 95 patients were examined by CE MR angiography following carotid duplex US in 59 cases and TOF MR angiography in 88 cases. Duplex US was done using LOGIQ 400 PRO system, MR angiography were performed by 1.5 T Siemens Magnetom Symphony unit. RESULTS - Stenosis of the internal carotid artery was confirmed in 67 cases and stenosis of the common carotid artery was seen in 10 cases. Bilateral ICA stenoses were detected in 17 patients and bilateral CCA stenoses could be revealed in 3 cases. The ICA stenosis was mild in 22 (33%), moderate in 18 (27%), and serious in 27 cases (40%). Occlusion was seen in 10 cases (15%). CE MR angiography showed stenosis at the origin of the CCA in 5 patients, at the origin of the vertebral and the subclavian artery in 10-10 cases that could not be detected by duplex ultrasound. Subclavian artery stenosis was seen in 15 patients, 7 of them presented subclavian steal syndrome. 13 patients had vertebral artery stenosis, 7 of them bilateral. 13 of the 20 VA stenoses were mild, 4 were found to be moderate and 3 were serious. In four patients the vertebral arteries were occluded. In six questionable cases MR angiography solved the problem. Reversed flow could be detected in 5 cases with duplex ultrasound suggestive of subclavian steal syndrome, which was later confirmed by TOF and CE MR angiography. TOF MR angiography showed stenosis on reconstructed images, which was not confirmed by neither duplex US or CE MR angiography. Paraganglioma was detected in one patient. CONCLUSION - In case of calcified plaques and abnormal arterial-course CE MR angiography contributes significantly to the detection of the stenosis. In cases with moderate and serious stenosis duplex ultrasound and MR angiography provided similar results. In case of occlusions the results of the two modalities were the same. The contrast-enhanced MR angiography gives the possibility to show the aortic origin of the supraaortic arteries in contrast to the duplex US and TOF MR angiography. To establish the diagnosis of subclavian steal syndrome the directional sensitivity of TOF MR angiography and duplex US is helpful adjunct to CE MR angiography.]

[Computer tomography based planning by personal computer in surgery of forefoot]

HUSZANYIK István, HEGEDŰS Franciska, RÓDE László

[BACKGROUND - In contradiction to traditional osteographic registrations CT pictures give the possibility of precise and size proportional measurements. Three-dimensional reconstructions can help in imaging of stereoscopic structures, however later reediting is not possible. Authors elaborated a CT based system for planning surgical interventions with personal computer. MATERIALS AND METHODS - The new method is described using a forefoot surgery model. The measurements were based on three subcapital osteotomy of 1st metatarsus. The length of 1st metatarsus, the 1st-2nd metatarsus index, the 1st-2nd intermetatarsal angle, and dorsoplantar movement of 1st-2nd metatarsal head were determined. RESULTS - The postoperative result of correction and pathologic bone movement can also precisely determined by this method. CONCLUSION - This method seems to be practical for elaboration of other new operating techniques, predicting and verifying their results before clinical use.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

Association of anterior thoracic meningocele and azygos lobe of the lung

DENIZ Ersay Fatih, SENAYLI Atilla, BICAKCI Ünal

Here we report an anterior thoracic meningocele case. Twoyears- old female patient was presented with kyphosis. Azygos lobe of the lung was also demonstrated during radiological studies. Posterolateral thoracotomy incision and extralpeural approach was performed for excision of the anterior meningocele to untether the cord. Although both anomalies are related to faulty embryogenesis and it is well known that faulty embryogenesis may also reveal coexisting abnormalities, we could not speculate a common mechanism for anterior thoracic meningocele and azygos lobe of the lung association.

[Successful radiological diagnostics in Bouveret’s syndrome]

KISS Katalin, FARKAS Szabolcs, LUKOVICH Péter, MAGYAR Péter, MESTER Ádám, MAKÓ Ernő†

[INTRODUCTION - Bouveret’s syndrome I is a rare clinical entity, a special form of gallstone ileus. Based on a case study the authors describe the clinical presentation, the complications and diagnostic work up of the Bouveret’s syndrome I. CASE REPORT - A 75-year-old female patient with repeated vomiting and haematemesis was examined. Known gallstones and obstructive jaundice was noted in the case history. Urgent gastroscopy was performed at admission, which proved haemorrhagic esophagitis as the cause of the haematemesis. A gallstone was found by endoscopy distal to the pyloric region obstructing the bowel lumen. Radiological examinations proved the presence of the stone exactly at the localization that was given. Surgery confirmed the diagnosis. CONCLUSION - Bouveret’s syndrome I should be considered in patients with repeated and long lasting vomiting and bile stone in the case history. Conventional X-ray may be sufficient to establish the diagnosis, however further imaging studies are needed to clarify exact anatomical situation and potential complications of the disease.]
