The psoas muscle attaches the lower portion of the spine to the femur. It helps with flexion of the hip and flexion of the lumbar spine. The muscle attaches along the side of the spine, to the vertebral bodies and the transverse processes. Infectious that occur in the spine, either in the disc spaces or the vertebral bodies, often may spread into the adjacent vertebral bodies. Pus may track along the psoas muscle. Abdominal infections may spread to the psoas muscle. Pus may spread along the psoas muscle to the groin.
Causes of Psoas Abscess
Psoas abscess can occur secondary to Crohn's disease, diverticulitis or colorectal cancer. Osteomyelitis of the spine can produce a paraspinal abscess that involves the psoas muscle. Tuberculosis and a ruptured abscess of the kidney or pancreas can lead to psoas muscle abscess.
Signs and Symptoms of Psoas Abscess
Pain occurs in the right or left lower abdomen, or both. Frequently, the discomfort is felt in the front of the thigh, the groin and the hip. The hip on the involved side is often kept flexed. A mass may be felt in the groin. Fever and chills occurs. Low back pain occurs in addition to painful walking.
