CTICasesCoal Workers' Pneumoconiosis
Imaging findings
Chest CT shows numerous fine, well-defined micronodules clustered primarily in a subpleural and upper-lung distribution, with some coalescing to form pseudo-plaques. Additionally, there is mediastinal and hilar lymphadenopathy, severe splenomegaly, and abdominal lymphadenopathy related to concurrent mantle cell lymphoma.
Key takeaways
Coexisting diseases are not uncommon (Hickam's dictum), and multiple diagnoses must be considered when imaging findings do not fit a single process. In a patient with known abdominal lymphoma, the presence of symmetric, upper-lung predominant micronodules and subpleural pseudo-plaques is highly characteristic of an occupational exposure such as coal workers' pneumoconiosis rather than atypical lymphoma metastases.
