Abstract
Bilateral thalamic stroke is usually due to compromised artery of Percheron, an anatomical
variation of the vascular supply of the thalamus. The stroke in this area is very
uncommon, and is mainly due to top of the basilar syndrome. Other causes are extremely
rare. We describe the case of a patient with a pituitary adenoma who underwent surgery
and later presented with a bilateral thalamic infarct, suggesting compromise of the
artery of Percheron. This would be the third case published in the literature about
this complication. We present a literature review about the vascular supply of the
thalamus, the artery of Percheron, and its involvement in pituitary surgery.
