Delayed presentation of psoas abscess previously misdiagnosed as deep venous thrombosis: A potentially devastating error

ABSTRACT Introduction: Psoas abscess is an uncommon condition seen only occasionally in daily surgical practice. Often, its clinical presentation is non­specific, frequently causing diagnostic uncertainty. Late presentation, delayed recognition and inappropriate management of this condition can often precede eventual diagnosis, especially in resource poor settings. Case Report: We describe the case of a 22­year­ old man who presented with a large psoas abscess which unfortunately had been misdiagnosed and treated as a deep venous thrombosis. Conclusion: This unusual case highlights the difficulties often encountered by clinicians when assessing and managing a patient with a psoas abscess. The diagnosis of a psoas abscess remains challenging. Clinicians must always remain vigilant to this diagnosis. Early recognition, confirmation with imaging and swift drainage remains the key to optimising patient’s outcome.
