Lesions of the Psoas Compartment

Mass-like lesions in the psoas compartment include:
  • Retroperitoneal hematoma: The case shown here. There is a heterogeneous mass in the expected region of the right psoas muscle.
  • Muscle asymmetry
  • Retroperitoneal fibrosis: Look for center of lesion surrounding the aorta and inferior vena cava.
  • Paraspinal abscess
  • Neoplasm
