Pott's disease in a person with progressive massive fibrosis.

Silicosis is the most common occupational lung disease and association with Mycobacterium tuberculosis infection is common. Although extrapulmonary tuberculosis cases are rare, skeletal tuberculosis is responsible for 10-35% of these cases. Pott's disease is the most common form of skeletal tuberculosis, but it is not commonly encountered today. A 49-year-old male patient presented to our clinic with complaints of back pain, leg pain, and weight loss for 9 months. His occupational history revealed that he worked as a dental technician and a sandblasting for 30 years. In 2002, he was diagnosed with pneumoconiosis. Thoracovertebral Computed Tomography and Magnetic Resonance Imaging showed lytic lesions in the anterior middle columns of the T6-T9 vertebrae and an anterior narrow angle kyphosis (Gibbus deformity) at the level of T9 vertebra. The findings were primarily evaluated in favor of Pott's disease abscess. Posterior segmental instrumentation and osteotomy were performed. The patient was evaluated as extrapulmonary tuberculosis, and anti-tuberculosis treatment was started. We present a case of pneumoconiosis with extrapulmonary tuberculosis and Pott's disease.
