ABSTRACT
BACKGROUND: The development of modern imaging studies such as high-resolution US and various MR imaging sequences have enabled their application to the examination of the gastrointestinal tract. OBJECTIVE. To compare radiological contrast studies, US and MRI in patients with Peutz-Jeghers syndrome (PJS). MATERIALS AND METHODS: Ten members of two families were evaluated. The patients were divided into three groups according to the presence of perioral pigmentations and current clinical symptomatology. Patients were examined using US, MRI and radiological contrast studies. RESULTS: In the disease-free family members ( n=3), no pathological findings were found. In asymptomatic ( n=4) and symptomatic patients ( n=3), polyps were demonstrated using contrast studies in all cases. MRI demonstrated all the polyps. Ultrasound revealed the polyps in three out of six patients. In addition to the polyps, intussusceptions were shown. There was no evidence of malignant transformation on any of the studies. CONCLUSIONS: Although PJS is a childhood or teenage disease, patients should be closely monitored during adulthood because of the development of gastrointestinal and extragastrointestinal malignancies. Contrast studies remain the gold standard. However, radiological follow-up could be undertaken by US or MRI, which would not impose a radiation burden during life-time follow-up.

Variations of the lower extremity venous system are common, and radiologists may frequently be confronted with such variations during daily clinical practice. However, variations in the arterial system of the lower extremity are extremely rare. The profunda femoris artery and arteries of the cruris are mainly subject to variation. This report describes an extremely rare arterial variation, duplication of the superficial femoral artery (SFA), in terms of the radiologic findings, clinical importance, and embryologic basis.

Primary malignant tumours of the stomach are very rare in children, most being lymphomas and sarcomas. The majority of primary gastric lymphomas are high-grade non-Hodgkin's lymphomas and are of B-cell origin. However, a significant number are low-grade B-cell lymphomas that are derived from mucosa-associated lymphoid tissue (MALT) that is not found in the normal stomach. Helicobacter pylori infection predisposes to the development of MALT in the stomach and provides the pathogenic background for MALT-type lymphomagenesis. To our knowledge, only eight paediatric cases of primary gastric lymphoma have been described. The diagnosis and follow-up of gastric lymphoma are mainly made by endoscopy. Nevertheless, radiologists must be aware of this disease because it may be observed on radiological examinations that are performed for non-specific upper digestive symptoms in children.
