Spontaneous Ureteral Urine Extravasation From Invasion of a High-grade Angiosarcoma

Abstract

A 69 year-old male with a past medical history of hypertension, diabetes, and atrial fibrillation presented to the Urology clinic with asymptomatic microscopic hematuria. His work up for hematuria included a negative cystoscopy and a computed tomography (CT) scan, which revealed what appeared to be a fluid collection around the left kidney with a perinephric infiltrative mass and two para-aortic enlarged lymph nodes.
