Disseminated tuberculosis is a relatively rare clinical condition, and cases with no history of the disease are sparse. A case of an 18-year-old Indian male is presented. He came with complaints of chest pain, coughing with expectoration, and loss of appetite. The diagnostic workup led to a definite diagnosis of disseminated tuberculosis with involvement of the lungs, pleura, mediastinal lymph nodes, and pericardium. He was initiated on a fixed-dose anti-tubercular treatment per the national guidelines.
