Psoas abscess is a serious health problem which presents with non-specific symptoms and signs. To reduce morbidity and mortality, it is important to diagnose the presence and extent of a psoas abscess accurately using imaging studies. Because the 67Ga scan may facilitate the early diagnosis of insidious infection and assist CT-guided percutaneous drainage of the abscess, we examined the value of 67Ga scans in 18 patients with psoas abscess. The imaging results of 67Ga scans (18 patients), computed tomography (CT) (16 patients) and bone scans (13 patients) were analysed. In this series, concomitant infections were very common (94%) in patients with psoas abscess. For detecting psoas abscess, the sensitivity of 67Ga scanning (92%) and CT (91%) was similar. However, 67Ga scanning is superior to CT in demonstrating concomitant infectious foci at other sites. Bone scanning is a sensitive tool for depicting osteomyelitis, which was common in this series of patients. We also found that increased vascularity in the psoas area was demonstrated by three-phase bone scanning in 60% of patients.
