Persistent primitive olfactory artery connected with middle cerebral artery: case report
A 78-year-old woman presented with headache. CT–angiography revealed a right PPOA. The vessel originated from the right distal A1, ran along the right olfactory tract toward the olfactory bulb, and made an abrupt posterior turn, ultimately becoming the distal MCA. In this patient, I identified the normal A1 and a short anterior communicating artery (Fig. ). Her headache was relieved with medication.
