CTICasesAccelerated Silicosis / Progressive Massive Fibrosis (PMF)
Imaging findings
Initial chest radiographs showed apical disease and hilar lymphadenopathy mimicking TB or sarcoidosis. Progressed to dense opacities consistent with PMF over one year.
Key takeaways
Occupational history is critical; the patient was a countertop worker (silica exposure). Misleading initial history (referred from a TB clinic) can lead to diagnostic framing bias.
