Pulmonary coccidioidomycosis refers to lung involvement with a systemic mycosis caused by the dimorphic fungus (mainly Coccidioides immitis andCoccidioides posadasi).
Pulmonary involvement it has been reported to occur in 95% of all cases of coccidiodomycosis.
It can be divided into three main categories:
- primary pulmonary coccidioidomycosis
- complicated pulmonary coccidioidomycosis
- residual pulmonary coccidioidomycosis
There can be many findings which include multiple nodules, interlobular septal thickening, consolidation, lymph node enlargement and pleural effusions. A multiple nodular pattern has been reported as being frequent and these may have a predominance towards the inferior pulmonary lobes 2. Nodule diameters may range from 0.5 to 3cm. They generally tend to have ill defined contours. Some nodules may coalescence. Cavitation of nodules has also been reported as a common feature. Rarely a miliary pattern may develop - esp in immunocompromised patients 4.
