Primary adrenal leiomyosarcoma with inferior vena cava extension in a 70-year-old man.

ABSTRACT

Primary adrenal leiomyosarcoma, a malignant soft tissue tumour originating from the smooth muscle of the inferior vena cava and adrenal vein, is rarely described in the literature. Cases are often diagnosed at an advanced stage as the tumour is not hormone-producing. We describe a 70-year-old man who presented with lower extremity swelling and abdominal varices and was subsequently found to have a large adrenal mass on imaging. Our case is among the few reported primary adrenal leiomyosarcomas in which a CT-guided biopsy was used to aid in diagnosis.
