Abstract
BACKGROUND: Reports on cardiac hemangioma detection by F-18-deoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) are extremely rare. CASE PRESENTATION: Here we describe a case of a 61-year-old man with hemangioma. CT revealed a tumor with a size of 60 mm. Magnetic resonance imaging showed high signal intensity on T2-weighted images. Hemangioma was initially suspected. However, PET/CT showed high FDG absorption, which led us to suspect a malignant tumor. The tumor was resected, and a cavernous hemangioma diagnosis was made by postoperative histopathological examination. CONCLUSIONS: This case may serve as a reference for clinicians to become more aware of the potential application of FDG PET/CT for cardiac hemangioma detection.
