Diagnosis With Brief Discussion
- Diagnosis
- Pulmonary cryptococcosis
- Radiologic Findings
- Chest radiograph shows a nodular opacity in left lower lung zone.
Contrast-enhanced chest CT images demonstrate 16mm solid nodule with two small nodules in RUL, and 17mm nodule with other smaller nodules in LLL.
The patient underwent CT-guided transthoracic core-needle biopsy. Pathologic specimen revealed many spore-form organisms in cytoplasm of multinucleated giant cells of alveolar space, which were morphologically consistent with cryptococci.
- Brief Review
- The most common CT finding of pulmonary cryptococcosis in immunocompetent host is single or multiple pulmonary nodules or masses, which are located predominantly in peripheral lung. be Cavitating nodules and cavitating consolidation may be present in 10% to 42% of the patients. . Less common findings include consolidation, ground-glass opacity, and mild interlobular septal thickening. Lymphadenopathy is reported in 17% to 20%. Pleural effusion is uncommon.
