Abstract
Intracranial dermoid cysts are nonneoplastic lesions that present a rare clinical entity. They account for 0.04% to 0.6% of all intracranial tumors. Such cystic lesions usually contain different ectodermal derivatives including hairs, sebaceous glands, apocrine gland and teeth. Dermoid cysts of foramen magnum occur very rarely, with few cases reported in the literature. Computed tomography (CT) and magnetic resonance imaging (MRI) are two main diagnostic tools. Here in this paper, we described a case of intracranial (foramen magnum) dermoid cyst presented with neurologic deficits that completely removed surgically.

Summary
Dermoid cysts are congenital ectodermal inclusion cysts that contain varying amounts of ectoderm derivatives. Clinical presentation of patients with brain dermoid lesions is variable They may be incidentally detected on brain computed tomography (CT) or magnetic resonance imaging (MRI) for complaints such as head trauma or headaches. They may cause a large mass effect and resulted in signs and symptoms related to compression of adjacent brain tissue structures [3] [4]. They may occur in parasellar region or posterior fossa and cerebellar vermis [10] In this case report study we presented a middle-aged woman with neurologic deficits related to dermoid cyst in foramen magnum that was confirmed by MRI and pathologic evaluations
