UNILATERAL TOTAL LUNG SEQUESTRATION: A RARE CONDITION

Tuberculin skin test was positive (17 mm, vesicular). There was no history of contact with a TB-positive patient. The diagnosis of the chest wall TB was made in view of histopathologic and image studies and the positive result of the tuberculin skin test. The patient underwent anti-TB treatment Such localisation of a TB process is rare in pulmonological practice accounting for 1–2% of TB cases. Tuberculous chest wall abscess may involve sternum, osteocartilaginous articulations, costal arches, costovertebral joints and vertebrae. The most common localisation is along costal arches and sternal margins. Chest computed tomography (CT) is recognised as a diagnostic tool of choice for the differential diagnosis of chest wall tumours. It allows for assessment of the nature and extent of the pathologic lesions in soft tissues and associated erosions of the bone structures as well as to examine lungs and mediastinum. A biopsy is required for histopathologic confirmation.
