[Bilateral adrenal hemorrhage induced by stress. Radiological diagnosis. Apropos of a case]. / Hémorragie surrénalienne bilatérale par stress. Diagnostic radiologique. A propos d'une observation.

Bilateral hemorrhage of the adrenal gland is a rare disease in adults. Although stress is often said to be the cause, it is rarely observed. The non specific clinical manifestations, and the absence of adrenal insufficiency demonstrate the importance of radiology. The diagnosis is made by ultrasonography and CT scan, which reveals an oval adrenal mass of high density that subsequently decreases in both size and density.

[Primary mediastinal choriocarcinoma. Apropos of 3 cases]. / Choriocarcinomes médiastinaux primitifs. A propos de 3 cas.

We report three cases about the diagnostic imaging features of mediastinal choriocarcinoma and during follow up. Computed tomography proved to be more accurate than plain X ray to show the topography and volume of the mediastinal mass hence providing a better approach for biopsy and surgical ablation of the residual tumoral tissues. However, CT cannot differentiate fibrous tumoral remnants from active malignancies and beta HCG is an important tumoral marker in the follow up.
