OBJECTIVE: A maxillofacial location of a hydatid cyst is rare, accounting 2% of cases. The purpose of this study was to review clinical and radiological features by emphasizing diagnostic difficulties. MATERIALS AND METHODS: Two observations of hydatid cyst with a maxillofacial location are presented. Two cases were investigated by panoramic dental radiography, an ultrasound and CT scan. MRI was done in one case. RESULTS: The first observation reports a 23-year-old woman who consulted for jugal tumefaction with pharyngeal extension evolving in spurts. The second observation was a 16-year-old girl, which consulted for a genian and masseter tumefaction with a tight trismus. In both cases, the imaging studies suggested the diagnosis of the hydatid cyst confirmed by the anatomopathologic exam. CONCLUSION: The hydatid cyst is an endemic parasitic pathology involving most often the lung and the liver. The maxillofacial location is exceptional. In cases of a cyst mass in an endemic zone, the diagnosis of the hydatid cyst must be entertained. CT scan and MRI provided a complete lesion workup. Treatment is surgical.

Osteoid osteoma and simple bone cyst are readily observed in long bones, but are much less common in the short bones of the foot. The association of these two tumors in the same foot is exceptional. We report the case of a 15-year-old girl who presented an osteoid osteoma of the talus and a simple bone cyst of the calcaneus of the left foot. The patient complained of pain in the rear foot for four months which worsened at night and was of the inflammatory type. The physical examination was normal. Standard x-rays revealed a simple bone cyst in the calcaneus which could not explain the nighttime inflammatory pain. Scintigraphy and computed tomography of the left foot revealed an osteoid oseoma of the talus. Biopsy total resection of the osteoid osteoma with curettage and filling with cancellous bone of the simple bone cyst were performed. The patient has been free of recurrence at three years follow-up.

Retrovesical hydatid cyst is rare, even in endemic regions. From a presentation of three cases, the authors will review the clinical findings and illustrate the imaging features of this pathology and relate diagnostic and therapeutic difficulties.

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.

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.

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.

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.

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.
