Overview

Pulmonary tuberculosis must be differentiated from other diseases that cause cough, fever, night sweats, hemoptysis and weight loss, such as: brucellosis, bronchogenic carcinoma, Hodgkin lymphoma, bacterial pneumonia, sarcoidosis, mycoplasmal pneumonia.

Differential Diagnosis

Pulmonary Tuberculosis

Disease Findings
Bacterial pneumonia Sudden onset of symptoms, such as high fever, cough, purulent sputum, chest pain. Consolidation on chest X-ray, leukocytosis.
Bronchogenic carcinoma Can be asymptomatic, usually at older ages (> 50 years old), cough, hemoptysis, weight loss
Brucellosis Fever, anorexia, night sweats, malaise,back pain , headache, and depression. History of exposure to infected animal
Hodgkin lymphoma Fever, night sweats, pruritus, painless adenopathy, mediastinal mass
Mycoplasmal pneumonia Gradual onset of dry cough, headache, malaise, sore throat. Diffuse bilateral infiltrates in chest X-ray.
Sarcoidosis Non-caseating granulomas in lungs and other organs, bilateral hiliar adenopathy, predominantly in African American females.
Adapted from Mandell, Douglas, and Bennett's principles and practice of infectious diseases 2010 [1]

Extra-Pulmonary Tuberculosis

Extra-Pulmonary Location Differential Diagnosis
Tuberculous Lymphadenitis Lymphoma, squamous cell carcinoma, papillary thyroid cancer, pyogenic infection
Skeletal Tuberculosis Multiple myeloma, bone metastasis, spinal cord abscess, osteoporosis
Tuberculous Arthrits Bacterial septic arthritis, pseudogout
Central Nervous System Tuberculosis Bacterial meningitis, viral meningitis, encephalitis
Tuberculosis Peritonitis Bacterial peritonitis, chronic peritoneal dialysis
