Intrathoracic and Intraabdominal Tuberculosis Lymphadenitis without Lung Involvement in an Immunocompetent Patient

Abstract

Extrapulmonary tuberculosis (EPTB) is defined as tuberculosis (TB) affecting organs other than lung. The most common site of EPTB is the lymph node. In adults, lymphadenopathy without a lung parenchymal infiltrate is rare and is usually observed in immunocompromised patients. We report a case of a 53 years old non-immunocompromised women from affected by intrathoracic and intraabdominal tuberculosis lymphadenitis without lung involvement. The patient presented with subacute fever, night sweat, fatigue, anorexia, abdominal pain, and weight loss. The diagnosis was made by the combination of computed tomography (CT) scans and histopathology studies. CT scans showed multiple lymph nodes involvement in the mediastinal and abdominal areas. Histopathology studies showed necrotizing lymphadenitis with positive acid-fast bacilli stain. The patient responded to (rifampin, isoniazid, pyrazinamide, ethambutol) therapy well and was discharged five days after initiating the treatment.
