[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.

[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.

[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.
