Abstract

Neurovascular conflict, often asymptomatic, necessitates investigation when neuropathy is suspected. Oculomotor nerve involvement is rare, commonly attributed to microvascular issues, trauma, tumors, or surgery. Arterial conflicts are typically more symptomatic. Clinical presentation includes ptosis and muscle paralysis, with pupillary asymmetry indicating compression of specific nerve areas. Imaging advancements aid in detection, highlighting vessels like the PCA, SCA, Pcom, and ICA, along with anatomical variants. Differential diagnoses encompass various vascular, infectious, inflammatory, and neoplastic conditions. Treatment begins with medical management, using steroids or carbamazepine, with microvascular decompression as a surgical option in persistent cases. Careful consideration is needed due to surgical risks. We aim to present an uncommon oculomotor neurovascular conflict caused by fetal posterior cerebral artery detected by aCT scan and MRI.
