[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.

[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.

[Value of MRI in the diagnosis of unilateral optic nerve aplasia: a case report].

Optic nerve aplasia is a rare congenital anomaly consisting of complete absence of the optic disc and nerve, ganglion cells and nerve fibers, and retinal blood vessels. Optic nerve aplasia may be associated or not with anomalies of the eye ball, and may be unilateral or more rarely bilateral, the latter sometimes associated with major central nervous system anomalies. We report the MRI appearance of a case of unilateral optic nerve aplasia associated with microphthalmos. Coronal T2 weighted and 3D T1 weighted images disclosed the absence of the 3 portions of the optic nerve. This observation shows the usefulness of systematic MRI in case of microphthalmos associated with suggestive anomalies of the fundus.

[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.

[Prenatal semiology of diastematomyelia].

Diastematomyelia is a rare spinal malformation characterized by a division of the spinal cord. More often, the two hemicords are separated by a midline and sagittal osseous or fibrocartilaginous spur. In this report we describe two cases of diastematomyelia detected at routine second trimester detailed sonography and further assessed by MRI and spiral CT with surface shaded 3D-reconstructions. In addition to providing diagnosis, prenatal evaluation helps differentiate between diastematomyelia with good or bad prognosis.

[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.

[Rare cause of ischemic cerebrovascular infarct in a young patient: cardiac hydatic cyst].

The authors report the case of a 28-year-old man in whom the diagnosis of hydatic cyst of the heart was strongly suspected on echocardiography and CT-scan and confirmed by surgery. The interest of this case is based the total clinical latency of this hydatic cyst discovered by echocardiography during a systematic checkup for cerebrovascular disorders. Echocardiography and spiral scanography with bidimensionnal reconstruction in coronal and sagittal planes allowed a rapid anatomic and topographic diagnosis. CT-scan also identified spread of echinococcosis and discovered a calcifield hydatid cyst of the liver and a multivesicular hydatid cyst of the left kidney.
