Mass lesions in the iliopsoas compartment (MLIPC) are uncommon in patients in departments of medicine and their incidence and etiologies are unclear. In a prospective study we diagnosed various MLIPCs in 7 patients during a 10-year period, representing 0.03% of admissions. Symptoms included abdominal or flank pain (4 cases), pain along the thigh (5), diminished psoas muscle strength (2), fever (2), and hypotension (1). MLIPC was suspected on clinical grounds in 5 cases. In all cases the diagnosis was established by computed tomography (CT). Tissue was sampled by needle biopsy in 4 and on surgery in 1. MLIPCs were caused by hemorrhage (2), infection (2), neoplasia (2) and inflammatory mass (1). Often MLIPCs are life-threatening so their timely diagnosis by early CT scan is important.
