—To describe and illustrate the common imaging features of various types of tuberculosis affecting the lungs, bones, gastrointestinal system, genitourinary system, lymph nodes and central nervous system.

Primary tuberculosis typically manifests radiologically as parenchymal disease, lymphadenopathy, pleural effusion, miliary disease, or atelectasis. The radiologic features of postprimary tuberculosis can be broadly classified as parenchymal disease with cavitation, airway involvement, pleural extension, and other complications. Osseous involvement in tuberculosis is frequently complicated by small parts abscess such us in the spine. Joint lesions are typically monoarticular and primarily involve the large weight-bearing joints. Gastrointestinal damage may be ulcerative, hypertrophic, or ulcerohypertrophic. The ileocecal region is the most common area of disease, peritoneum and...

A- Pulmonary tuberculosis 1. Primary tuberculosis: — Most common form of pulmonary tuberculosis. — Asymptomatic. — Typically manifests radiologically as: Parenchymal disease (atelectasis) Lymphadenopathy (fig.1) Pleural effusion Miliary disease — The chest radiographs may be normal. — CT is more sensitive for parenchymal diseases++ Sequelae of PT are more see as: Retractile opacity (+/- calcif) (fig.2) Calcified hilar lymph nodes (fig.3) 2. Post primary tuberculosis: — Reactivation of a previously primary infection. — Rarely a continuation of the primary disease. — Lesions predominated in apical...

—Tuberculosis can affect any organ system.— Variety of clinical and radiologic features.— Tuberculosis can mimic many other disease.— Significant complications. —Long and difficult treatment. Importance of recognizing the different radiological appearance for a rapid diagnosis.
