Hungarian Radiology - 2005;79(02)

[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.]

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

FORRAI Gábor, BODOKY György

[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.]

[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.]

[Fournier’s gangrene]

MÁTÉKA Ilona, MORVAY Zita, PALKÓ András

[INTRODUCTION - Fournier’s gangrene is a rare, rapidly progressive specific form of necrotizing fasciitis that involves the soft tissues of the genital and perianal regions. The infection may spread from these regions along the abdominal wall or towards the lower limbs and has a very high mortality rate. History of the patient, the clinical features and the imaging techniques all together help to recognize the condition and to localize the affected area. CASE REPORT - We present the case of a thirty-year-old male patient, who had on admission a swollen left lower limb. Deep venous thrombosis was excluded by Doppler us. A few days later an other us examination revealed the fasciitis of the left thigh and the scrotum, originating from the deep gluteal bed-sore of the patient. A CT was performed to define the extent of the process and help the planning of the surgical intervention. The patient has recovered well after the operation. CONCLUSION - Due to the high mortality rate of Fournier’s gangrene it is essential to recognize this condition in time and to provide the appropriate surgical intervention or antibiotic therapy. Imaging modalities play a very important role in the diagnosis of Fournier’s gangrene.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

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.
