Multi-Drug-Resistant Tuberculosis Peritonitis: A Case Report.

The increasing incidence of tuberculosis raises concerns globally, impacting both developing and developed nations. Abdominal tuberculosis stands out as the most prevalent form of extrapulmonary tuberculosis. This case report details the diagnostic journey of a young male with abdominal TB complicated by concurrent HIV infection. The patient presented with night sweats and substantial weight loss, concurrently receiving a naive human immunodeficiency virus (HIV) diagnosis with an undetectable CD4 count. Imaging revealed abdominal lymphadenopathy concealing the pancreatic head while bronchoscopy unveiled TB in the lung. The patient faced septic shock and bilateral pulmonary embolism, possibly due to immune reconstitution inflammatory syndrome (IRIS). The patient then developed ascites, and a diagnosis of TB peritonitis was made based on low serum ascites albumin gradient (SAAG) and a positive acid-fast bacillus (AFB) result in the para-aortic lymph node. Treatment complexity arose from drug resistance to isoniazid and ethambutol.
