Abstract
|
|
|
|
Alveolar adenoma is a rare pulmonary neoplasm with a female predominance, and it was considered to be a histologic variant of sclerosing hemangioma in the past. A chest X-ray usually shows a well-defined, peripheral, solitary nodule similar to that of sclerosing hemangioma. Chest CT shows a solitary, well-defined, peripheral nodule with homogeneous density and no contrast enhancement, which is contrary to marked contrast enhancement of sclerosing hemangioma. We report the first case of alveolar adenoma with spotty enhancement of the nodule similar to that of sclerosing hemangioma on contrast enhanced CT, based on the presence of stromal vessels in the interstitium of the compact alveolar area on histopathologic comparison.
