CTICasesHistoplasmosis Lymphatic Satellite Pattern
Imaging findings
MIP CT reconstruction shows a dominant calcified pulmonary nodule with multiple small satellite nodules tracking along the bronchovascular bundle to a calcified hilar node, demonstrating a classic lymphatic drainage pattern.
Key takeaways
The satellite nodule pattern and linear lymphatic tracking to calcified regional lymph nodes is highly characteristic of granulomatous fungal infections (especially histoplasmosis or coccidioidomycosis).
