[Radiological diagnostics of the pancreas neoplasms - Onco Update 2005]


[Authors reviewed the recent results of pancreas tumour radiological diagnostics and the place of the imaging and interventional methods. Systematical review of the most recent articles were summarized (July 2003-December 2004) in the following subjects: the etiology and clinico-pathology, general diagnostic and therapeutical questions of early pancreatic neoplasms, abdominal ultrasound, computed tomography, multidetector computed tomography, magnetic resonance imaging, MR-cholangiopancreatography, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound, intraductal ultrasound, endoscopic ultrasound-guided cytology, percutaneous biopsy, positron emission tomography, positron emission tomography - computed tomography, special pancreatic tumours. Experiences about the pancreas diagnostic methods are accumulating year-to-year rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering in the daily practice. These are the reasons why the up-to-date knowledge of the literature is mandatory.]

[Radiologic diagnosis of the diseases of the pediatric gynecology]

LÓRÁND Ágnes, HARKÁNYI Zoltán, LOVAS Györgyi, HÉJJ Ildikó

[The basic examination of the pediatric pelvic organs is the transabdominal ultrasound which provides useful information about the anatomy and the pathological changes and in the vast majority of cases it is sufficient for treatment planning and to establish the diagnosis. Additional examinations are needed in case of complex developmental anomalies, in suspition of tumor, in staging and follow up examinations of tumors. Among the modern imaging methods the use of CT and MRI can be considered. The authors described the most frequent diseases in their practice and gave a brief overview on anatomical and physiological basics which is necessary for the exact interpretation of the examinations.]

[Early detection of adult femoral head necrosis]

GION Katalin, PALKÓ András

[Adult avascular femoral head necrosis is common in young adulthood, and in 80% of cases affects male patients. The disease is bilateral in 40-80 %, and it may take several years to develop on the contralateral side. Late diagnosis and lack of early therapy can cause progressive disease and finally movement restraint. The diagnosis in early stage is crucial for choosing the most effective strategy in therapy. It is important to be aware of pathogenesis, clinical course and the differential diagnostic options of the disease, and these should be associated to the diagnostic findings at different imaging modalities. Based on this concept, we conclude that MR examinaton is the method of choice for the early (reversible) stage assessment. MRI of the hip is also able to evaluate and follow up the healthy contralateral side without further strain.]

[Dudoenum obstruction caused by duodenal diaphragm]

RUDAS Gábor, SEKYRA Pavel, PUMBERGER Wolfgang, POVYSIL Brigitta

[INTRODUCTION - Duodenum obstruction is a rare gastrointestinal developmental anomaly. It may be complete or incomplete. The incomplete or intrinsic form is often caused by an intraluminal membrane or web duodenal stenosis. The passage is existed with the help of a small perforated lake. Clinically the leading sign is the vomiting. CASE REPORT - A three days old baby admitted because of vomiting. Abdominal X-Ray and US could not found any reason of vomiting but the gastrointestinal contrast series had diagnostic value. Surgery proved the radiological diagnosis. CONCLUSION - For the diagnosis the conventional XRay and ultrasound is not sufficient in every case, the gold standard is the gastrointestinal contrast examination.]

[Czech dysplasia metatarsal type]

IVO Marik, MARIKOVA Olga, DANA Zemkova, MIROSLAV Kuklik, KAZIMIERZ Kozlowski

[We report a further female patient with the recently described new bone disease, Czech dysplasia metatarsal type. Czech dysplasia metatarsal type (CDMT) is an autosomal dominant debilitating disorder. Its constant phenotypic trait is hypoplasia/ dysplasia of the 3rd and/or 4th toes. “Congenital hip dysplasia” or “hip disease” is commonly evoked in the family history. The clinical course may be severe, incapacitating the patients early in life, or progress slowly with increasing hip and spine pain. This girl's phenotype and radiographic findings are similar to the seven previously reported cases.]

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


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.

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.

Investigation of risk factors, topographic location and stroke mechanisms of unilateral isolated and posterior cerebral ARTERY thalamic infarcts

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.
