title: [Primary mediastinal choriocarcinoma. Apropos of 3 cases].
abstract: 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.
