| Abstract|| |
Hemangiomas are extremely rare tumors of the heart that may present with pericardial effusion, dyspnea, chest discomfort, palpitations, or syncope. Few published reports have highlighted the utility of 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) in the evaluation of cardiac lesions. We report a case demonstrating the utility of 18F-FDG PET-CT in a young man who presented with gross pericardial effusion and suspicion of metastatic carcinoma on fluid cytology.

A 41-year-old male presented with history of weight loss and epigastric discomfort for 6 months. His electrocardiogram revealed sinus tachycardia, Chest X-ray showed money-bag appearance of the heart and two-dimensional echocardiography revealed gross pericardial effusion. He underwent pericardiocentesis and 500 ml straw-colored fluid was drained. Fluid cytology examination showed atypical cells with suspicion of metastatic carcinoma. Contrast-enhanced computed tomography of the chest and abdomen revealed gross pericardial effusion with hyperdense content within the effusion, which was attributed to hemorrhagic content.18 F-fluorodeoxyglucose positron emission tomography-computed tomography (18 F-FDG PET/CT) done for localizing primary tumor [Figure 1] revealed FDG-avid pericardial thickening (SUVmax 5.5) along with mild FDG uptake in the periphery of a soft-tissue lesion within the pericardial cavity (SUVmax 3.3, arrowhead). Mild left pleural effusion was also noted. No abnormal FDG-avid lesion was noted elsewhere in the body and PET/CT findings were suggestive of the primary pericardial tumor with pericardial effusion and thickening.

Mild left pleural effusion was also noted. Excision of the pericardial lesion revealed cavernous hemangioma|

Resection of the pericardial mass was done and gross examination revealed yellowish-brown well-encapsulated mass measuring 6 cm × 5 cm × 3 cm showing hemorrhagic and solid areas on cut section. The histopathological analysis of the resected specimen showed tumor with large blood-filled cavernous spaces with outer dense fibrinous exudate suggestive of cavernous hemangioma. No areas of atypia, mitosis or necrosis were noted. The patient recovered uneventfully from the surgery and is on follow-up.
Hemangiomas are extremely rare tumors of the heart that may present with pericardial effusion, dyspnea, chest discomfort, palpitations or syncope. Hemangiomas can be capillary, cavernous, or arteriovenous type. High-contrast enhancement is the typical feature on CT and MRI. Pericardial hemangiomas are extremely rare. Few reports on findings of cardiac hemangioma on 18 F-FDG PET/CT have been published.,,,,,, Being benign tumors, cardiac hemangiomas show relatively low FDG uptake while malignant cardiac tumors show higher FDG uptake. In a study by Rahbar et al., SUVmax cutoff of 3.5 was able to differentiate between malignant and benign cardiac tumors with a sensitivity of 100% and specificity of 86%. In addition, in patients with hemorrhagic pericardial effusions, after exclusion of tuberculosis,18 F-FDG PET-CT scan can be of great assistance to exclude metastatic tumors and PET-CT findings can guide toward the diagnosis of cardiac hemangioma, especially when CT findings are equivocal as in the present case.
