Abstract

Objective

In areas with endemic histoplasmosis, incidental pulmonary nodules are common. Rate of malignancy and applicability of current tracking guidelines in these regions remain unclear.

Methods

A total of 148 cases of incidental pulmonary nodules tracked with chest computed tomography were reviewed for radiologic characteristics, diagnosis, number, and size.

Results

Of the nodules, 87.8% were benign and 12.2% malignant; 30% of nodules > 20 mm were malignant. Number of nodules (P= .14) and granulomatous disease (P= .71) were not related to malignant diagnosis.

Conclusion

Malignancy was lower than expected in nodules > 20 mm. Appropriate tracking guidelines for incidentally discovered nodules in histoplasmosis endemic regions must be determined.
