Intracaval and intracardiac leiomyomatosis of uterine origin.

Intracaval leiomyomatosis of uterine origin is a rare disease. Extension to the right heart is exceptional. Based on the review of 11 cases reported in the literature and the case presented herein, which was treated successfully, the diagnostic and therapeutic problems are discussed. Diagnosis should be suggested when a female patient operated on previously for myofibroma of the uterus by hysterectomy, presents with a picture of cardiac myxoma. Diagnosis can be confirmed by iliocavogram and computerized tomography of the abdomen. Excision calls for a cardiac procedure under extracorporeal circulation and caval exploration which may be performed either simultaneously or as a two stage procedure.
