[Suprarenal leiomyoma of the vena cava. A rare differential adrenal gland tumor diagnosis].
Leiomyomas are benign tumors that can arise in the smooth muscle and can appear practically everywhere; hence, they must be taken into consideration as a rare possibility in the differential diagnosis of numerous tumors. While leiomyomas of the peripheral vessels are a relatively common finding, they are rarely found in the central vessels. Only a few cases of leiomyomas in the vena cava are known. In contrast to malignant leiomyosarcomas, leiomyomas usually grow towards the lumen. We report on the rare case of a leiomyoma in the inferior vena cava that appeared in the image to be located in the adrenal gland. Therefore, transperitoneal extirpation of the site was undertaken. It was only during surgery that a tumor emanating from the vessel wall became apparent. Thus, after an initial laparoscopic approach it became necessary to change to open resection of the tumor with cavotomy and resection of the vessel wall. The histopathological work-up revealed a benign leiomyoma and further imaging diagnostics gave no indication for the presence of metastases.
