Pott's Disease in a Patient with Subtle Red Flags.

ABSTRACT

BACKGROUND: Tuberculosis (TB) is now rare in developed countries; however, it is an important diagnosis for the Emergency Physician to be able to make. Classically thought of as a respiratory disease, TB can present in other ways, making it more challenging to recognize. CASE REPORT We report the case of a 41-year-old woman who presented to the Emergency Department with a 4-week history of back pain. A diagnosis of T12 osteomyelitis and right psoas muscle abscess was made after magnetic resonance imaging. The concurrent finding raised concern for TB as psoas muscle abscess is usually found along with spinal TB. A computed tomography-guided fine-needle aspiration confirmed the diagnosis. This patient's social history was negative for many of the classic predisposing factors associated with TB immunosuppression, personal travel, crowded living conditions. Repeated investigation into the patient's history revealed a visit several months prior from a family member from Vietnam who had been treated for TB. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? It is important for Emergency Physicians to be aware of the relatively high incidence of TB as a cause for concurrent psoas abscess and vertebral osteomyelitis.
