A 60-year-old woman presented with a 5-year history of chest discomfort and occasional syncope. Physical examination was unremarkable. Transthoracic echocardiography revealed a large, highly echogenic mass filling the right ventricle. Further evaluation with contrast-enhanced cardiac computed tomography (CT) showed a lesion with a gourd-like appearance, consisting of a larger portion (45 mm x 35 mm) and a smaller portion (15 mm x 10 mm) connected together, adherent to the right ventricular free wall (Figure 1A, arrows and asterisks). Early-phase imaging showed minimal irregular enhancement within the tumor, while delayed imaging at 90 s demonstrated more tortuous, vine-like enhancement patterns (Figure 1B, arrows and asterisks; supplementary material online, Video 1), supporting a diagnosis of hemangioma. The patient underwent surgical excision of the tumor under direct visualization, and histopathological examination revealed irregularly dilated vascular spaces consistent with a cavernous hemangioma. The postoperative course was uneventful, and the patient was discharged 1 week later. At a 2-year follow-up, the patient had a good prognosis with no recurrence.

Cavernous hemangiomas of the heart are rare benign tumors, accounting for approximately 2.8% of all primary cardiac tumors,¹ and they typically arise from the ventricles, valves, and atria, rarely from the epicardium.² Hemangiomas can be classified based on histopathology into cavernous (with multiple dilated thin-walled vessels), capillary (with small capillaries), and arteriovenous (with malformed arteries and veins) types. Most cardiac cavernous hemangiomas lack specific clinical manifestations, and symptoms depend on the size, growth pattern, and attachment site of the tumor.³ Similar to our case, the patient experienced occasional syncope. Diagnosis of cardiac cavernous hemangioma relies on imaging studies, and this case demonstrated typical CT features with progressive filling on delayed enhancement, making preoperative diagnosis possible. Additionally, CT imaging provided precise information about the relationship between the tumor and the right ventricle, which was useful for surgical planning.
