Bilateral persistent hypoglossal arteries: a case report and literature review
- 47 Downloads
Bilateral persistent hypoglossal arteries (PHAs) are extremely rare, with only 5 cases reported in the English-language literature. Using magnetic resonance angiography, we diagnosed a case in which the left side was a typical PHA and the right side was presumed a PHA variant that supplied only the posterior inferior cerebellar artery.
