BackgroundIsolated sphenoid mucoceles are rare, but because of their close proximity to important vasculonervous structures, local extension may result in serious consequences.Case DescriptionA 47-year-old patient presented with headaches, meningismus, and a left homonymous lateral hemianopia. We report the atypical evolution of a posttraumatic sphenoid mucocele invading the sellar region and extending into the subarachnoid space with compression of the right optic tract, and we describe its surgical management. Further, with the aid of cadaveric specimens, we aim to analyze the precise pathway followed by the expanding collection from an anatomic perspective.ConclusionsAnatomic knowledge of the sellar and parasellar regions is the key to understand the process of how sphenoid mucoceles may extend intracranially. Early endoscopic drainage with a large sphenoidotomy allows favorable outcomes and prevents serious consequences.
