Hungarian Radiology - 2002;76(02)

[INTRODUCTION - Stromal tumors of the gastrointestinal tract are rare and the diagnosis is often not straitforward. CASE REPORT - A case of a 75-year-old male patient with a duodenal stromal tumor is presented. The differential diagnosis was difficult, since the mass mimicked a tumor of the pancreatic head. Authors briefly review of the characteristics of gastrointestinal stromal tumors. CONCLUSION - The role of diagnostic imaging in the diagnosis of stromal duodenal tumors is secondary. Correct diagnosis can be established using immunhistological and electromicroscopis studies, only.]

[The incidence of Hirschsprung disease with associated congenital anomalies]

WEISENBACH János, KONDOR Ariella, KHEZRI Seddiq, VAJDA Péter

[INTRODUCTION - Several publisactions described the association of Hirschsprung disease with other congenital anomalies. Most studies were in relation with the neurological, ophthalmological and ear-nose-throat disorders. The authors did not find any publication in the Hungarian literature presented other anomalies in patients with Hirschsprung disease. PATIENTS AND METHODS - The data of 43 patients treated for Hirschsprung disease at the Department of Paediatrics of Pécs University was analysed. The most frequent associated anomalies e. g. Down syndrome, omphalocele, anorectal malformation, annular pancreas, torticollis, syndactylia, Meckel diverticulum, upper urinary tract disorder and undescendent testis were studied. The patients who had several congenital anomalies were evaluated separately as well as those having congenital inguinal hernia. The authors compared the number of congenital anomalies occurred in patients with Hirschsprung disease with the incidence of these congenital disorders occurred in non-Hirschsprung patients in the literature. RESULTS - Among 43 patients, 6 children had associated congenital anomalies. 3 patients had only one of the following disorders: undescendent testis, urinary tract duplication and Down syndrome. 3 patients suffered from multiplex congenital anomalies: 1. Down syndrome with annular pancreas and torticollis. 2. Omphalocele, anal atresia, vesicoureteric reflux and syndactylia. 3. Anus atresia, Meckel diverticulum and limb (radius) hypoplasia. In addition 3 patients had other anomalies such as unilateral and bilateral inguinal hernia and umbilical hernia. CONCLUSION - On the basis of our results we can state that the incidence of other associated congenital anomalies are higher in patients with Hirschsprung disease. Single organ developmental anomaly is rare, it usually occurs in association with multiorgan disorders. Most likely this is the explanation why patients with Hirschsprung disease have more associated anomalies.]

[Atypical diaphragmatic herniation causing bowel obstruction]

ERDŐSI Éva, MÉSZÁROS Anikó, GREXA Erzsébet

[INTRODUCTION - A 21-year-old woman presented with iatrogenic diaphragmatic hernia causing bowel obstruction. CASE REPORT - Plain abdominal X-ray and barium swallow examinations showed a diaphragmatic hernia causing partial gastric obstruction. Surgery confirmed the radiological diagnosis. The hernia was located atypically at the centre of the diaphragm. CONCLUSION - The cause of the hernia was probably related to a pyogenic necrosis due to subphrenic abscess after cholecystectomy performed 2 years earlier, treated by drainage and repeated surgical interventions.]

[Dilemma of screening for lung cancer]

MONOSTORI Zsuzsanna

[Lung cancer still represents one of the greatest and unsolved health problem of the world. The lung cancer mortality rate is the highest among all cancer cases in both genders. While the world is focusing on both primary and secondary prevention, the position of mass screening for lung cancer is complex and controversial, yet. This raises many issues that can only solved by a multidisciplinary approach. This summary is intending to help the radiologists to make the right decision in our modern computerised world. Nowadays one of the most important question is if screening of the high-risk group with low-dose spiral CT is efficient and cost-effective.]

[A case of gastrointestinal stromal tumor of the small intestine causing gastrointestinal bleeding]

TAMÁS Krisztina, KIRÁLY Ágnes, KALMÁR Katalin, WENINGER Csaba, TORNÓCZKY Tamás

[INTRODUCTION - The neoplastic disease of the small intestine - especially the gastrointestinal stromal tumor - is a rare disease, its diagnostics is not an easy task. CASE REPORT - The authors examined a 71-year-old female patient who presented hematemesis and melena. A small intestine tumor was detected by endoscopy and abdominal computed tomography as the source of gastrointestinal bleeding. Histology proved gastrointestinal stromal tumor. The characteristics of the tumor were reviewed based on the literature. CONCLUSION - Radiological imaging plays a significant role in the diagnosis of gastrointestinal stromal tumors.]

[Gastrointestinal stromal tumors]

BAHÉRY Mária

[Gastrointestinal stromal tumors are the most common mesenchymal neoplasm of the gastrointestinal tract. Gastrointestinal stromal tumors are characterized by remarkable variability in their differentiation potential. They are defined by their expression of KIT (CD117), a tyrosine kinase growth factor receptor. The expression of KIT is important to distinguish gastrointestinal stromal tumors with immunohistochemically method from other mesenchymal neoplasms such as leiomyomas, leiomyosarcomas, leiomyoblastomas and schwannomas. Pathologically proved gastrointestinal stromal tumors are appropriate KIT-inhibitor therapy. Gastrointestinal stromal tumors arise with variable frequency throughout the gastrointestinal tract, they most frequently occur in the stomach (40-70%), followed by the small intestine (20-30%), colorectum (5- 15%) and esophagus (<5%). The most gastrointestinal stromal tumors arise within the muscularis propria, they most commonly have an exophytic growth pattern and manifest as dominant extraluminal masses. Radiologic features of gastrointestinal stromal tumors vary depending of tumor size and organ of origin. They are characteristically well circumscribed, sharply defined and have hemorrhage, necrosis or cyst formation. The radiologic features of gastrointestinal stromal tumors are often distinct from those of epithelial tumors. There are no specific radiologic features to separate gastrointestinal stromal tumors from other mesenchymal tumors, yet.]

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

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.
