CTICasesSilicosis mimicking Sarcoidosis in a Construction Worker
Imaging findings
CT in a construction worker shows large central conglomerate PMF masses, upper lobe volume loss, calcified subpleural deposits, and calcified paraesophageal lymph nodes. The patient had a history of concrete pouring and concrete dust exposure.
Key takeaways
Construction work involving concrete pouring and sandblasting is a common source of silica exposure in the US. The radiographic features of silicosis can closely mimic sarcoidosis, but occupational history and paraesophageal nodal calcifications help differentiate them.
