[Castleman's disease with thoracic localization. Apropos of a case with x-ray computed tomography. Review of the literature].

Castleman Disease is a rare benign condition of uncertain etiopathogeny. The most frequent localization is thoracic, often discovered by a routine chest radiography. The diagnosis is histological. We report one case, characterized by his very long course (25 years) and calcifications. Ct scanning showed enhancement after contrast material administration, and proved the adherence with the adjacent soft tissues, justifying surgery.
