title: Giant epidermoid cyst as an unusual presentation of hypoglobus and ptosis.
abstract: A 24-year-old man presented with a large right frontal epidural epidermoid cyst that resulted in right hypoglobus and right upper eyelid ptosis. CT and MRI revealed a bone-destroying mass involving the right frontal bone and eroding through the right orbital roof. Complete surgical removal was performed through a frontal craniotomy. After surgery, there was near-complete resolution of the hypoglobus and ptosis.
