Abstract
BackgroundFinding an aneurysmal bone cyst in the skull is rare and for a neurosurgeon to come across such lesions in the sphenoid bone with orbital extension is even rarer.Case presentationWe report a case of a 16-year female who presented with a three-month history of headache, proptosis, and deterioration of vision. Pre-operative imaging studies which included NCCT head and MRI brain, suggested the lesion to be an aneurysmal bone cyst of the greater wing of the sphenoid, with extension into the orbit. Intraoperative findings did corroborate with the preoperative imaging findings and were again confirmed later from the histopathology report.ConclusionAneurysmal bone cysts of sphenoid bone with orbital extension, though rare, can be excised completely, without hampering the cosmesis. Being benign, patients can have a prolonged recurrence-free period if the lesion is completely excised.

Summary
Aneurysmal bone cysts, as a new clinicopathologic entity was first described by Jaffe and Lichtenstein in 1942 [1] These lesions commonly affect the metaphysis of long bones. Involvement of skull bones is rare (3%) and sphenoid bone aneurysmal bone cysts with orbital extension are even rarer [2, 3]. These handful cases present mostly in their first three decades of life. We report a case of an aneurysmal bone cyst involving the greater wing of sphenoid bone with extension into the lateral orbital wall, which was totally excised without any cosmetic defect. The whole lesion was curetted out with meticulous attention
