[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.

[Esophageal duplication in children. Report of 7 cases].
UNLABELLED: Esophageal duplications represent 10 to 20% of esophageal malformations and 15 to 20% of digestive duplications. METHODS: The authors report a series of seven cases observed between 1985 and 1999. RESULTS: The sex ratio was 2.5. The diagnosis was made before the age of six months in five cases. The clinical presentation included respiratory signs in six cases and digestive signs in five cases. The diagnosis was made on the association of a mediastinal mass behind vertebral malformation in five cases. The duplication was cystic in five cases and tubular in two. A perforation in the pleura occurred in one case of tubular duplication. The intervention consisted of total excision of the duplication in four cases and subtotal resection in two cases. For the seventh patient, who presented a perforation of the duplication in the pleura, the operation comprised a thoracic drainage associated to feeding gastrostomy. The histologic examination of the six operative specimens confirmed the diagnosis of esophageal duplication. Six patients survived and have favorable evolution with an average follow-up of four years. DISCUSSION: Esophageal duplications represent 15 to 20% of digestive duplications. Their clinical presentations are variable. Their diagnosis is often made before the age of two years, when a posterior mediastinal mass is associated with vertebral malformations. Apart from the tubular form, which is rare, diagnosis is confirmed by the histologic study of the operative specimen. CONCLUSION: Esophageal duplications are rare and often pose a problem of positive diagnosis. Their treatment is surgical and should be undertaken before the appearance of complications.
[Pneumatic dilatation of caustic esophageal stenosis in children. Report of five cases].
The ingestion of caustic substances is a frequent accident in the child. The treatment of caustic strictures of the esophagus, which constitute the most frightening complication, varies from conservative treatment to esophageal replacement. We report the preliminary results of a prospective work established since July 1998 and aimed at evaluating the role of pneumatic dilatation in the treatment of these injuries. STUDIED POPULATION: The series included five boys with an average age of six years. Two children were neurologically handicapped. RESULTS: The caustic product was soda (three cases), a dishwasher solution (one case) and bleach (one case). Dysphagia was constant and concerned the semi-fluids in four cases. The stricture was extended over an average length of 4 cm. The total number of dilatations was 36, with an average of seven sessions/patient. No complication was noted. The result was good in four cases. The only failure was noted in a child who presented a gastroesophageal reflux secondary to the scarring phenomena. CONCLUSION: Pneumatic dilatation constitute a therapeutic mean whose results are attested. The best treatment remains, however, preventive: it is the setting out of reach of the child the dangerous products.

[Digestive perforations and occlusions].
Acute abdominal disorders are common reasons for consultation at the emergency department. The diagnosis of all acute abdominal disorders begins with a careful history and physical examination. When appropriate, the clinical examination should be supplemented by conventional plain abdominal radiography. Gastrointestinal perforation and obstruction are very commonly encountered in the diagnosis of acute abdomen. Plain abdominal radiographs are the initial diagnostic methods of choice. In some circumstances, ultrasonography and CT may be valuable for the evaluation of the cause of abdominal disorder.

[Extramedullary hematopoiesis: multiple mediastinal localizations].
Intrathoracic extra-medullary hematopoiesis is a compensatory mechanism usually seen in thalassemia. The authors report a case with multiple mediastinal localisations fortuitously discovered. CT has allowed diagnosis and led percutaneous biopsy.
