Abstract

Malignant psoas syndrome (MPS) is a rare clinical condition caused by cancer invasion of the iliopsoas muscle and has very poor prognosis. We report a case involving a 58-year-old woman with bilateral MPS caused by advanced bladder cancer. Rapid progress of a severe crouching posture with multiple deep venous thromboses was an important symptom of this case. Although 4 cycles of chemotherapy were administered, the patient died 8 months following disease onset. Since, these noteworthy symptoms have never been previously reported, in this report, we present the characteristic physical findings using photographs and cancer-related events that occur in MPS.

Keywords: Bladder cancer; MPS, malignant psoas syndrome; Malignant psoas syndrome.
