[Dental-CT imaging]

SZABÓ Tünde, BAGI Róbert, MONOKI Erzsébet, BANDULA Mihály

[Nowadays the widespread application of dental and oral surgical procedures and the use of dental implants established the need of special examination of the jaw. These implants are mainly made of metal and surgically imbedded into the edentulous jaw. Metallic artefacts deteriorate the diagnostic value of conventional X-ray. In the past years, the use of multislice CT technique and dental reformatting program can demonstrate structures which were hardly or not visible due to their shape and location. The aim of this review is to introduce this special dental CT program.]

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.

[PHARMACEUTICAL PREVENTION OF THE UPPER GASTROINTESTINAL SIDE-EFFECTS OF NSAID THERAPY]

HERSZÉNYI László, TULASSAY Zsolt

[Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce pain and inflammation in patients with rheumatoid arthritis and osteoarthritis. However, they are also associated with a significant risk of gastrointestinal events with clinical and economic consequences. It is mandatory to rationalise the use of different NSAID treatment strategies in patients with varying degrees of gastrointestinal and cardiovascular risk. In patients for those aged <65 years with no previous gastrointestinal event and not concurrently on aspirin (low risk patients), the use of an NSAID should be considered as appropriate. For patients with a previous gastrointestinal event (high risk patients) or who concurrently received aspirin, an NSAID alone should be rated as inappropriate and either a coxib or selective cyclooxygenase-2 inhibitor, or an NSAID + proton pump inhibitor combination is considered as appropriate. Finally, for patients aged >65 years with a previous gastrointestinal event and on aspirin (patients with very high risk) a coxib in conjunction with a proton pump inhibitor is considered to be the best therapeutic strategy.]

[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.]
