Abstract: | A 65-year-old-man was admitted for evaluation of a transient ischemic attack. A 4.5 x 5.3-cm right atrial mass and a patent foramen ovale were identified by echocardiography. A 0.5-cm lesion was identified in the left temporal lobe of the brain by magnetic resonance imaging. Positron emission tomography was used to differentiate a tumor from an infarct in the brain. The cardiac and the brain lesions were successfully resected. Histopathologic study of the atrial and cerebral tissue demonstrated that these were metastases from a previously excised scalp desmoplastic malignant melanoma. The patient remains well at 14 months' follow-up. |
