Greater wing of sphenoid, the home for aneurysmal bone cysts: a case report

Abstract

Abstract Background Finding 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 presentation We 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. Conclusion Aneurysmal 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.
