Case Reports
Bilateral paramedian thalamic and mesencephalic infarcts in a newborn due to occlusion of the artery of Percheron.
Bilateral paramedian thalamic and mesencephalic infarcts are infrequently reported in adults, and to our knowledge, has never been reported in a child. The presumed etiology is an occlusion of the artery of Percheron, an uncommon vascular variation, in which a single common trunk from one of the P1 segments of the posterior cerebral artery provides bilateral irrigation to the paramedian thalami and midbrain. ⋯ Although some improvement of these symptoms does occur, complete recovery is rare. We present here a full-term male neonate, whose right-hand sided clonic seizures on day-of-life 2 prompted neuroimaging, which revealed bilateral paramedian thalamic and mesencephalic infarcts, suggestive of an occlusion of the artery of Percheron.
