Internal carotid artery stenosis due to myxoma in a patient
The present case has been published in the journal Neurology.

A 50-year-old man presented with an episode of transient loss of consciousness, aphasia, and right hemiparesis. Spotty cutaneous pigmentation and multiple subcutaneous lentigines were observed.

A left atrial myxoma protruding into the ventricle was identified on echocardiography. MRI demonstrated isointense mass within the lumen of the left internal carotid artery, and digital subtraction angiography demonstrated irregular intraluminal filling defect that resulted in severe stenosis.

Pathologic examination confirmed the diagnosis of carotid artery myxoma. The combination of skin pigmentation and multiple myxomas met the criteria for Carney complex.
