    AbstractThe precise definition of the accessory meningeal artery was not available until 1961. It can originate from the maxillary artery or middle meningeal artery and supplies the meatus and membranous portion of the auditory tube, the lateral pharyngeal muscle, and the medial pterygoid muscle; Laterally, it supplies the lateral pterygoid muscle, the extracranial part of the mandibular nerve, the pterygoid venous plexus, and the sphenoid periosteum. Here, we present a 70-year-old male patient who applied to the neurosurgery clinic with complaints of chronic headaches and dizziness. Magnetic resonance angiography and computed tomography angiography showed hypoplasic appearance of the left internal carotid artery and an enlarged accessory meningeal artery variant merging with its ophthalmic segment.Copyright © 2023 Elsevier Inc.
