Leiomyoma of the Left Renal Vein A Report of a Case

Abstract

Only a few cases of leiomyoma of the vena cava or iliac vein and, according to our knowledge, only one case of renal vein leiomyoma have been reported. We report a patient with leiomyoma of the left renal vein. Tumour resection was performed by resecting a part of the vein along with the tumour and by ligation of the vein. Left kidney drainage was established through the preserved ovarian vein. In order to establish a diagnosis, careful pathologic examination of multiple sections has to be done and because of the potentially malignant behaviour, long-term follow-up after total resection is necessary.

Clinical progression of renal vein leiomyoma: A case report

“…Vascular leiomyomas are further classified as capillary angioleiomyomas, cavernous type or venous angioleiomyomas [6]. Among a few hundred cases of venous smooth muscle tumours described in literature, majority are leiomyosarcomas that originate in the Vena Cava [7]. Currently, the differential diagnosis between leiomyoma and leiomyosarcoma is only histopathological after surgical resection.…”

“…But they can grow along the vein wall and spread within its lumen in a downstream direction which can lead to thrombosis. Hence, the recommended procedure is excision of the mass and ligation of the feeder vessels [7,8].…”

“…Upon extensive search of literature, only five cases of leiomyoma of renal vein were found to have been reported [1,7,[9], [10], [11]]. The displacement of viscera by the growing tumour is likely responsible for the intractable pain experienced by these patients.…”

Leiomyoma of the Renal Vein: A Rare Tumor Presenting as a Renal Mass

“…Zelić et al reported a patient with leiomyoma of the left renal vein in 2009. Tumour resection was performed by resecting a part of the vein along with the tumour and by ligation of the vein [ 13 ]. Kefeli et al reported a 52-year-old man with leiomyoma of the left renal vein in 2009.…”
