Which finding suggests a benign etiology in the differential diagnosis of a solitary pulmonary nodule?

Question

Quizplus · Accepted Answer

The finding that the nodule is completely calcified is consistent with a benign etiology, such as a granuloma or hamartoma, rather than a malignant process. A nodule that has been present on prior films (option D) does not necessarily exclude malignancy, and the size of the nodule (option A) and age of the patient (option B) are not definitive factors in determining malignancy vs. benignity.
