Aneurysmal bone cyst (ABC) is an uncommon benign lesion that rarely presents in the craniofacial region. Aneurysmal bone cysts represent nearly 1.4% of all bone tumors, and among those, only 3% are located in the cranium. In this study, we report on an ABC located in the sphenoid bone with superior nasal cavity and ethmoid extension. The presenting symptom of our patient was headache, followed by diplopia, loss of visual accuracy, and abduction restriction. We successfully resected the lesion by a combined subcranial-midfacial degloving approach without any complications or recurrence.
