[Imaging of mesenterial panniculitis - Case report]

KOVÁCS Anita, KISS Ildikó, PALKÓ András

[INTRODUCTION - Mesenterial panniculitis is a rare benign disorder, however it is important to be familiar with, because of the difficulties in differential diagnosis. Authors describe the characteristic imaging signs of the disease based on their two cases. CASE REPORTS - Two male patients (72 and 62 years old) presented with uncertain abdominal pain and weight loss. Acute pancreatitis, chronic gastritis and duodenitis are noted in their case history. The laboratory parameters were normal and the physical examination revealed a palpable epigastrial terime in both patients. Abdominal ultrasound and CT examinations depicted different degree of mesenterial infiltration with lymph node enlargement. Histological analysis of the biopsy sample proved the process to be benign in the first patient. The mass was surgically removed in the second one and histology proved mesenterial panniculitis. CONCLUSION - Mesenterial panniculitis is a benign, chronic non-specific inflammatory disorder. Its appearance may simulate malignant diseases, thus making differential diagnosis is important. Abdominal ultrasound, CT and result of image guided biopsy play an important role in the diagnosis, in case of which conservative therapy and regular follow-up is sufficient.]

[Multisegmental tuberculous spondylodiscitis in a patient with Helicobacter pylori infection]

SZÁNTÓ Dezső, SZŰCS Gabriella, DITRÓI Edit

[INTRODUCTION - Prospective randomized examination has been verified association between asymptomatic chronic Helicobacter pylori infection and systemic vascular inflammation and endothelial dysfunction in certain cases. CASE REPORT - A case of a 71 year-old female patient is described with proven coexisting primary tuberculous bronchoadenitis, secondary tuberculous spondylodiscitis and Helicobacter pylori infection as a cause of uncertain abdominal disorder. The patient's height decreased by 9 cm during 6 months, since the onset of the symptoms. The diagnosis was based on respiratory function test, positive rapid ureal test, bronchoscopy, cytologic and microbiological examinations. On dorsolumbal spinal plain films showed wedge, biconcave crus and mass deformities of nine vertebras. High serum level of CRP and C3 complement was suggestive of acute reactive inflammation. Before the introduction of drug therapy an MR examination was planned, however the patient died of an acute myocardial infarct on the 8th day after admission The postmortem findings proved the presence of pulmonary and vertebral tuberculosis, there was no evindence of aortocoronal and spinal vasculitis. The epispinal tissues were not involved. CONCLUSION - The patient’s case history, autopsy findings and the literature data are suggestive of the role chronic Helicobacter pylori infection in the development of spondylodiscitis and the deterioration of the disease.]

[Radiological diagnostics in head and neck malignancies - Onco Update, 2006]

GŐDÉNY Mária, BODOKY György

[Imaging plays a crucial role in defining disease burden and thus therapy planning in head and neck cancer (HNC). Lately accuracy of pretreatment staging has become critical since non-surgical therapy has become a widely accepted treatment possibility. The referring clinician is responsible for accurate data collection, pretreatment staging, evaluation of therapy response and post-treatment evaluation of the HNC. Correctness of these highly depends on the expertise and experience of the evaluating radiologist therefore being familiar with the latest literature is essential. This article is a review of papers published in 2005 and 2006 focusing on the clinical significance of the latest imaging results in head and neck cancer diagnostics.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm

BÉRES-MOLNÁR Anna Katalin, FOLYOVICH András, SZLOBODA Péter, SZENDREY-KISS Zsolt, BERECZKI Dániel, BAKOS Mária, VÁRALLYAY György, SZABÓ Huba, NYÁRI István

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

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.

Extraskeletal, intradural, non-metastatic Ewing’s sarcoma. Case report

OTTÓFFY Gábor, KOMÁROMY Hedvig

Intracranial localization of Ewing’s sarcoma is considerably very rare. Herein, we present clinical and neuroimaging findings regarding a 4-year-old boy with intracranial Ewing’s sarcoma. He was born prematurely, suffered intraventricular haemorrhage, posthaemorrhagic hydrocephalus developed, and a ventriculoperitoneal shunt was inserted in the newborn period. The patient endured re­gular follow ups, no signs of shunt malfunction nor increased intracranial pressure were observed. The last neuroima­ging examination was performed at 8 months of age. Upon reaching the age of 4 years, repeated vomiting and focal seizures began, and symptoms of increased intracranial pressure were detected. A brain MRI depicted a left frontoparietal space-occupying lesion infiltrating the superior sagittal sinus. The patient underwent a craniotomy resulting in the total excision of the tumour. The histological examination of the tissue revealed a small round blue cell tumour. The diagnosis was confirmed by the detection of EWSR1 gene translocation with FISH (fluorescent in situ hybridization). No additional metastases were detected during the staging examinations. The patient was treated in accordance to the EuroEwing 99 protocol. Today, ten years onward, the patient is tumour and seizure free and has a reasonably high quality of life.

[The majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]
