Complex Case Management of Mycobacterium Tuberculosis Extrapulmonary Manifestation to the Right Sacroiliac Joint

Abstract

While Mycobacterium tuberculosis is a common bacterial pathogen that infects the respiratory system, especially in endemic regions, it may uncommonly manifest in other organ systems, such as the nervous, gastrointestinal, or musculoskeletal systems. Sacroiliac joint infections are rare, and only 1%-5% of all infections are tuberculous in nature. Given nonspecific inflammatory signs in both laboratory and radiologic examinations, early identification of the causative agent can be difficult. In this report, we present the case of a 29-year-old Eritrean woman who presented with an uncommon extrapulmonary tuberculosis manifestation of the right sacroiliac joint. The patient reported pain for two years before a formal diagnosis with multiple computed tomography scans demonstrated fluid collections about her right hip and thigh. The patient's medical history of developmental delay, psychosis, outdated medication documentation, non-therapeutic use of numerous psychiatric medications contraindicated for traditional anti-tubercular therapy, and socioeconomic history of a lack of social support and treatment arrangements with the patient's caregiver all complicated the treatment course. Given the rise in tuberculosis cases worldwide and vulnerability factors in patients with mental illnesses such as poverty, homelessness, diabetes, and HIV infection that can predispose patients to tuberculosis infections, early diagnosis and treatment are essential to reduce long-term consequences and improve clinical outcomes. Further research in the development of new tuberculosis treatment plans is essential to addressing an equitable treatment course alongside fighting against the recent rise in drug-resistant tuberculosis.
