Chest X-rays from two mineworkers, with interpretation according to the ILO International Classification of Radiographs of Pneumoconioses Revised, 2022 edition. Case 1: Radiograph quality Grade 2 (right rotation and inadequate penetration), showing small round opacities, shape and size (q/q) and profusion (2/2), localised in the right middle and lower zones, as well as in the left upper, middle and lower zones. A large opacity (A) next to the left heart border and pleural abnormality: left costophrenic angle obliteration by pleural effusion (ef). In the absence of TB, these radiological features are compatible with silicosis. Case 2: Radiograph quality Grade 2 (left rotation and inadequate penetration) showing diffuse small round opacities, size and shape (r/q), profusion (3/2), localised in the right, middle and lower zones, as well as the left upper, middle and lower zones, and large opacities (B) in the left upper zone and background ground glass opacities; cavity (cv) in right upper zone. These radiological features are suggestive of silico-TB.
