Ophthalmoplegic “Migraine” as a Presenting Symptom of Dermoid Cyst of the Cavernous Sinus: A Case Report and Review of the Literature

Dermoid cysts are common congenital benign tumors that arise from entrapped embryonic epithelial nests and consisted of keratinized squamous epithelium with dermal appendages and adnexal structures, and epidermoid cysts are similar but without dermal appendages [1,2]. While subcutaneous dermoid cysts are commonly seen in children, intracranial dermoid and epidermoid cysts are rare and account for 0.04-0.7% of intracranial tumors [3]. They maybe suspected after specific or non-specific neurologic symptoms such as cranial nerve palsies, diplopia, and meningismus [2-12]. We herein report a rare case of adermoid cyst of the cavernous sinus presenting with ophthalmoplegic migraine.
