Overview

The majority of patients with pulmonary tuberculosis will have CT abnormal findings, such as micronodules, interlobular septal thickening, cavitation and consolidation.

Computed Tomography

Pulmonary Tuberculosis

• Chest CT abnormalities are seen in the majority of patients with active pulmonary tuberculosis.
• CT finding include:

• Micronodules
• Interlobular septal thickening
• Cavitation
• Consolidation.

• Micronodules are most commonly located in the subpleural region and peribronchovascular interstitium.

Extrapulmonary Tuberculosis

Disseminated Tuberculosis

Abdominal Tuberculosis

• CT findings in the a pancreatic and spleen infection with tuberculosis may mimic a pancreatic cancer.
• Shown below there is CT scan of the pancreas demonstrating a mass in the pancreatic tail and metastasizes in the spleen.
