Systemic involvement was reported in 28/35 cases (80.0%). Patients with an abnormal chest study (fibrosis, granuloma, calcifications and other findings) but no mention of confirmed pulmonary disease by the original authors were not considered to have lung disease. Also, we considered miliary tuberculosis only when the authors used the term "miliary". Cases with central nervous system (CNS), abdominal, peritoneal, adrenal and pericardial involvement were reported separately. Confirmed pulmonary tuberculosis occurred in 15/35 (42.8%) of cases, miliary tuberculosis in 7/35 cases (20.0%), CNS involvement in 2/35 cases (5.7%) and abdominal and peritoneal involvement in 2/35 cases (5.7%). There was 1 case of TB adrenalitis and 1 case of TB pericarditis. All patients were started on antituberculous treatment (ATT). Treatment regimens were variable and medications included rifampin, isoniazid, pyrazinamide and ethambutol, among others. Case-by-case description of the ATT is available in Table 3. Death was reported in one case. This particular case was reported by Ni et al in 1982. The patient was a 30-year-old female with remote pulmonary tuberculosis who was diagnosed with syphilitic uveitis on presentation. The eye was enucleated and pathology revealed Langerhans giant cells (LGCs) which can be found in both TB and syphilis. The TB etiology was therefore not recognized and the patient died 6 months after presentation from generalized tuberculosis. In the remaining cases, patients were either referred to as alive or no mention of death was made by authors.
