LEIOMYOSARCOMA OF THE INFERIOR VENA CAVA WITH BONE METASTASIS -REPORT OF A CASE-

Abstract

It is believed that leiomyosarcomas of the inferior vena cava have a relatively low growth rate and a low malignant potential, but few cases of the disease are able to be resected surgically. We present a case of leiomyosarcoma of the inferior vena cava with bone metastasis which was successfully resected.
A 73-year-old woman was admitted to the hospital because of back pain. Chest X-ray examination revealed a tumor shadow and osteolysis at the right 6th rib. CT, magnetic resonance imaging (MRI), and angiography revealed a tumor about 3 cm in size in the vicinity of the inferior vena cava. Operative procedures included resection of the inferior vena cava including the tumor, reconstruction of the vein using Goatex graft with a ring 20 mm in diameter, and then resection of the right 6th rib.
Histopathologically, leiomyosarcoma of the inferior vena cava and its metastasis to the rib were identified. There have been no signs of recurrence, as of 7 months after the operation.
