Psoas as an Unusual and Overlooked Place for a Metastatic Tumor

Abstract

Abstract We report a case of a 60-year-old hemodialysis patient who clinically mimicked psoas abscess, which was subsequently proven to be from metastatic disease seconddary to uroepithelial tumor. The patient presented with 3 weeks history of fever, weight loss and back pain. Computer tomography (CT) scan of abdomen and pelvis revealed psoas muscle infiltration not amenable to drainage by interventional radiology. Careful history to provide additional clues to the diagnosis is of paramount importance in this condition.
