Bilateral psoas abscess: atypical presentation of spinal tuberculosis.

Three patients who came to the surgical outpatient department of 'Postgraduate Institute of Medical Education and Research', Chandigarh, India with features suggestive of acute abdomen are presented. On thorough evaluation, they had bilateral psoas abscess and on detailed investigations, tuberculosis was found to be the etiological factor. They were treated conservatively with good follow-up results. Psoas abscess may be clinically difficult to diagnose because of its rarity, insidious onset of the disease, and non-specific clinical presentation which can cause diagnostic delays resulting in high morbidity. Early diagnosis and appropriate management remains a challenge for clinicians. All three patients presented here have recovered following detailed investigation and appropriate management. The diagnosis of spinal tuberculosis should be considered in patients with vertebral osteomyelitis, psoas abscess, and appropriate risk factors such as a history of previous exposure in both developed and developing countries, as tuberculosis is re-emerging as an important etiological factor in spinal pathologies.
