摘要

Meningiomas are the most common extra-axial tumors of the central nervous system. They are slow-growing, benign lesions usually originating from the dura. They are usually detected incidentally. Anterior clinoid meningiomas are important because of their proximity to critical structures such as the optic canal and internal carotid artery. Due to their somatostatin receptor expression, especially SSTR2, 68Ga-DOTA0-Tyr3-octreotate ([⁶⁸Ga]Ga-DOTATATE) positron emission tomography/computed tomography (PET/CT) imaging has been used in both the diagnosis and follow-up of meningiomas. We report a rare case of anterior clinoid meningioma detected incidentally on [⁶⁸Ga]Ga-DOTATATE PET/CT.
