Mucoceles of the anterior clinoid process are very rare (1%). Enlarging mucoceles of the anterior clinoid process can cause pressure symptoms of surrounding structures. We reported a case of a 53 years old gentleman who presented with acute spontaneous progressive monocular vision loss and left frontal headache. His left eye had only light perception at initial presentation. Magnetic resonance imaging revealed an anterior clinoid process mucocele impinging the left optic nerve. The mucocele was successfully decompressed via a transnasal endoscopic approach. However, his left eye vision remained poor despite the surgical decompression of the optic nerve. Delayed detection and advanced age are inaugurally identified as poor prognostic features for this pathology.
