Pitfalls to avoid: psoas hypertrophy mimicking retroperitoneal fibrosis. 1981

M J McLoughlin

Mild obstructive uropathy and medial deviation of the ureters were observed in an athletic young black male, raising the possibility of retroperitoneal fibrosis. These findings were shown by computed tomography and ultrasonography to be due to psoas muscle hypertrophy.
