A Case of Solitary Pulmonary Capillary Hemangioma

Abstract

Solitary pulmonary capillary hemangioma (SPCH) is a very rare disease that has been reported to be difficult to diagnose preoperatively because the unenhanced computed tomography (CT) findings resemble adenocarcinoma in appearance. On the other hand, the findings of contrast-enhanced (CE) CT have not been reported as far as we could find in PubMed. In this article, we report a case of SPCH with its chest radiograph and dynamic CECT. Dynamic CECT could depict the pathologic features of capillary proliferation, especially dense in the central component of the lesion, edema, and congestion of the alveolar interstitium, and intra-alveolar edema in the periphery of the lesion. Dynamic CECT might be helpful for differentiating SPCH from other solitary pulmonary nodules.
