[Asymptomatic saphenous vein graft aneurysm: a case report].
The authors report the case of a 48-year-old man with a history of coronary bypass graft 15 years earlier. The follow-up by routine chest radiography showed a right paracardiac opacity, which MRI conformed to be an aneurysm of the saphenous vein graft.
[Superior mesenteric artery aneurysm revealing a Behçet disease: a case report].
Arterial involvement in Behçet's disease is rare. It represents one of the fashions of expression of this pathology. We report an observation of a 32-year-old man who was hospitalised for an intense abdominal pain. Doppler ultrasound and computed angiography showed a superior mesenteric artery aneurysm. The patient was operated in urgency and operating suites were simple. The etiologic inquiry of this aneurysm ended in the diagnosis of Behçet disease. The result underline the need to search for Behçet's disease in all cases of arterial involvement in young patient. The treatment of the aneurysm should not be delayed.
[A rare aetiology of the post-partum fever: ovarian vein thrombophlebitis].
OBJECTIVES: To clarify the contribution of the doppler and the CT in the balance aetiology of a fever of the post-partum and to connect it with a thrombophlebitis of ovarian vein. PATIENTS AND METHODS: Five patients presented there post-partum a fever with pointed abdominal painful syndrome. A doppler and a CT were performed. RESULTS: Doppler showed a hypoechoic tubular structure located forward and laterally with regard to the psoas with a flat spectre in pulsed Doppler in every case. CT confirmed the diagnosis of a thrombophlebitis of the right ovarian vein in three cases and left in two cases. Evolution after anticoagulation and an antibiotic therapy was favourable with regression of clinical signs and doppler evaluation. CONCLUSION: In front of any fever of the post-partum, it is necessary to evoke a thrombophlebitis of the vein ovarian, although it is about a rare aetiology. In spite of the superiority of the CT-scan and RP imaging for such a diagnosis, doppler is a simple and reproducible diagnostic tool for the monitoring which must be practised in first intention.
MRI in amyotrophic lateral sclerosis: hyperintensity of the corticospinal tract.
Amyotrophic lateral sclerosis is the most common form of motor neuron disease. The diagnosis is based on clinical and electromyography criteria. The primary role of imaging in amyotrophic lateral sclerosis is to exclude other causes such as cervical degenerative disk disease, Chiari malformation or multiple sclerosis. Imaging is also helpful in atypical cases of the disease.

[Imaging of pulmonary hydatid cyst in children].
PURPOSE: We present the various imaging features of pediatric pulmonary hydatidosis based upon a series of 232 cases. The importance of chest radiographs and thoraco-abdominal ultrasound is emphasized. PATIENTS AND METHODS: A retrospective study of 232 children with pulmonary hydatidosis is presented. The 232 cases (130 boys and 102 girls, age range: 18 months to 14 years) were studied between January 1982 and December 2001. Chest radiographs were available in all cases, chest ultrasound in 156 cases and abdominal ultrasound in 212 cases. CT was only performed in 40 cases. Surgery was performed for all patients. Diagnosis was confirmed with serology tests and/or pathological study of resected cysts. RESULT: The total number of pulmonary cysts detected on chest radiographs was 344. The right lung was more frequently affected than the left (208 lesions). A simple cyst was the most commonly observed lesion (220 cysts). Complicated forms were noted in 118 cases. 180 cysts were observed at ultrasound. A simple cyst presenting as an anechoic mass was noted in 140 cases. In 38 cases, the lesion was heterogeneous. In two lesions endocystic germinal membranes were detected. CT visualized 50 lesions. Thirty three lesions were complicated with endocystic floating or collapsed membranes. Bronchiectasis was observed in seven cases. CONCLUSION: Chest radiographs and thoraco-abdominal ultrasound are very useful for the diagnosis of pulmonary hydatidosis and evaluation of lesion extension. CT is useful for diagnosis of atypical or complicated lesions and to detect bronchiectasis.
[Omental lipoblastoma: a case report].
Lipoblastoma is a rare benign neoplasm of foetal fat tissue. To our knowledge, less than ten cases of omental lipoblastoma have been reported in the literature. We present a new case of omental lipoblastoma in a 3-month old girl. The role of CT in the diagnosis and surgery planning of this tumor will be discussed.

Intrahepatic spontaneous portosystemic venous shunt: value of color and power Doppler sonography.
Spontaneous portosystemic venous shunts (SPVSs) within the hepatic parenchyma are rare. Fewer than 50 cases have been reported, and most of them were diagnosed by angiography. We present a case of SPVS diagnosed by color Doppler sonography in a 5-year-old boy admitted for bleeding due to rupture of esophageal varices. Conventional color and power Doppler sonography as well as CT showed a large shunt between the posterior branch of the right portal vein and the inferior vena cava. We believe that accurate diagnosis and follow-up of SPVS can be done with color Doppler sonography without resorting to angiography.
