A 64-year-old man presented to our hospital with visual loss on the left eye due to central retinal artery occlusion diagnosed by another ophthalmological hospital. Magnetic resonance imaging revealed small multiple cerebral infarctions on bilateral hemisphere. Transesophageal echocardiography was performed, which revealed a mass lesion like a tumor with calcification on the mitral valve. We suspected that a mass lesion is calcified amorphous tumor (CAT). Surgical resection of the mass lesion was performed, and it was diagnosed CAT by pathological examination. CAT is considered as high risk of cerebral embolism, surgical treatment should be considered as early as possible.
