The combination of calcified mediastinal nodes, lung fibrosis, nodules in a subpleural and along the fissures makes sarcoidosis the most likely diagnosis in a middle aged woman.

Calcified nodes are also commonly seen in previous TB infection and in people with an history of silica dust exposure .

TB can be associated with upper lobe fibrosis as can silicosis.

Lung nodules are usually present in cases of pneumoconiosis.
