Download as PPT, PDF7 likes4,297 views
A 52-year-old female patient presented with complaints of breathlessness and dry cough for the past 6 months. She has a history of treated pulmonary tuberculosis 3 years ago and treated Pott's spine 2 years ago. Examination revealed wheezing and generalized pigmentation. Chest X-ray showed bilateral lung parenchymal lesions and hilar lymph node calcifications. The final diagnosis was occupational lung disease of silicosis complicated by silicotuberculosis due to exposure to silica particles in her work in sand filtration for brick production.
