[Unusual appearance of axillary lipoblastoma of infancy].

Lipoblastoma is an uncommon benign soft tissue tumor of infancy and early childhood with a predilection for the extremities. CT and MRI can confirm the presence of fat components in the tumor. In addition, MRI better shows the anatomical extent. By showing lipoblastoma proliferation, histology confirms the diagnosis. Gross total excision is the treatment of choice. The authors report a case of unusual lipoblastoma of the axillary region, composed of fatty components with multiple cystic areas presenting at birth, with recurrence 9 months after excision.

[Emergency ultrasound diagnosis of ovarian torsion in children : nine case reports].

OBJECTIVE: To report the ultrasonographic aspects of ovarian torsion in nine pediatric cases. PATIENTS AND METHODS: The age range was from 16 months to 14 years. The patients presented with a variety of symptoms, including pain in the site of torsion. Ultrasonography was performed in all patients, and color Doppler studies in four. RESULTS: Ultrasonography showed a cystic mass in six patients, a solid mass with peripheral cysts in two patients and an adnexal cyst in one patient. Color Doppler revealed absence of flow in three patients. The patients were treated by coeliosurgery. CONCLUSION: Ovarian torsion is a serious gynecologic emergency. Torsion is rare during childhood and has a non-specific clinical presentation. Ultrasound and Doppler are the imaging study of choice. The ovarian salvage was attributable to the combination of delay in patient presentation and surgical delay.

[Paraganglioma and pregnancy].

A paraganglioma is an extra-adrenal pheochromocytoma, rarely observed during pregnancy. Maternal prognosis depends on early diagnosis and multidisciplinary management prior to tumor resection. The tumor is localized by ultrasonography or MRI. During the post-partum, and if MRI is not available, CT is often sufficient. We report a paragangliona in a patient with intrauterine fetal demise at 27 weeks gestation diagnosed by ultrasonography and computed tomography, who underwent surgical resection.

[Pericardial hydatid disease: three case reports].

Hydatid disease of the heart is very rare, representing about 0.2 to 2% of all cases. Most hydatid cysts of the heart are located within the left ventricular wall. Pericardial location is also very rare and patients present with various symptoms. US and CT have a primary role in the diagnostic workup of this disease.

[Cholestatic icterus due to primary duodenal lymphoma].

Primary lymphoma of the duodenum presenting with obstructive jaundice is a rare entity. We report a case of primary non-Hodgkin lymphoma of the duodenum producing biliary obstruction, definitively diagnosed by ultrasound-guided fine needle biopsy. Complete remission of the disease occurred after chemotherapy.

[Acute non-traumatic mediastinitis].

UNLABELLED: Acute mediastinitis is uncommon. When it occurs, it usually follows an esophageal perforation or thoracic surgery. CASE REPORT: We report on a case of a ten-year-old girl with non traumatic mediastinitis secondary to a pleuro-pulmonary infection due to Klebsiella pneumoniae.

[Tuberculosis of the breast: a case report].

Tuberculosis of the breast is rare. It occurs in young women. Because the clinical and imaging findings are non specific, the diagnosis of a breast cancer is often suggested. This requires to obtain cytology and/or histology for a definitive diagnosis. On the basis of a case report of tuberculosis of the breast in a 14 years old girl, imaged by ultrasonography and computed tomography, we attempted to demonstrate the contribution of imaging and associated diagnostic pitfalls.

[Post-traumatic hepatic artery pseudoaneurysm. A case report].

CASE REPORT: We report a case of traumatic hepatic artery pseudoaneurysm in a 9-year-old child. The diagnosis was made by duplex sonography and helical CT angiography. Arteriography confirmed and managed the lesion with transcatheter embolization. CONCLUSION: The traumatic hepatic artery pseudoaneurysm is an uncommon complication of liver trauma in children whose diagnosis is made by duplex sonography and CT angiography. Endovascular embolotherapy is the treatment of choice.

[Subcapsular hematoma of liver during pregnancy: report of 4 cases].

A Subcapsular hematoma of the liver is a rare but very serious complication of pregnancy. Diagnosis is confirmed at imaging (Ultrasound, CT, MRI) since clinical symptoms are not specific and biological signs have a delayed manifestation. The management of this complication depends on the integrity or rupture of Glisson's capsule. We report the cases of 4 patients and review of the literature.

[Spinal intradural hydatid cyst. A case report].

The authors report the case of a 13-year-old girl in whom the diagnosis of intradural hydatid cyst was suspected on CT scan and MRI and confirmed at surgery. The interest of this case is related to the extremely rare location and its severe prognostic. CT scan and MRI can easily make an anatomic and topographic diagnosis of the intradural hydatid cyst.
