“…Intracranial dermoid lesions are usually located in midline such as suprasellar region. They may also occur in parasellar region or posterior fossa and cerebellar vermis [10]. Here 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 also pathologic evaluations.…”

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.

“…The most common locations of intracranial dermoid cysts are midline in the sellar, parasellar, and frontonasal regions [ 18 ]. The incidence of intracranial dermoid cysts is low, with reports suggesting that they make up less than 0.5% of primary intracranial tumors, to between 0.1-0.7% of intracranial tumors [ 18 - 20 ]. Involvement of the CPA is rare and may be secondary to the caudal extension of a dermoid cyst originating in the parasellar region [ 15 , 20 - 21 ].…”

“…The rupture of a dermoid cyst can be spontaneous, due to its growth, induced by trauma to the head, or during surgical excision [ 15 ]. Dermoid cyst rupture causes the release of primarily cholesterol breakdown products into the CSF, which may result in chemical meningitis, recurrent meningitis, abscess formation, empyema, elevated intracranial pressure, obstructive hydrocephalus, cerebral vasospasm, and/or seizures [ 15 - 20 ]. Finally, in rare circumstances, dermoid cysts can also undergo malignant transformation into squamous cell carcinoma [ 18 ].…”

Diagnostic Dilemma: Cerebellopontine Angle Lipoma Versus Dermoid Cyst

Both lipomas and dermoid cysts of the cerebellopontine angle are rare tumors. These tumors differ in their embryological origin but share similar features on imaging. Both of these congenital lesions can be found in the cerebellopontine angle (CPA), and symptomatic clinical presentation is dictated by the location of the lesion. This paper demonstrates a unique case in which a CPA lipoma was misidentified as a dermoid cyst, leading to surgical intervention. Further, the paper provides a literature review of CPA lipomas and dermoid cysts to aid readers in further differentiating between these two unique tumors.

“…[5][6][7] Intracranial dermoids are found in the posterior fossa, supra, and parasellar regions. [8][9][10] Dermoids enlarge slowly and accumulate viscous or semi-solid yellow material composed of desquamated epithelium, sebaceous gland secretions, fat, oil, and hair. The presence of skin components (hair follicles, sebaceous, and sweat glands) in the cyst wall and contents distinguishes dermoids from epidermoid cysts.…”

Microsurgical Resection of Craniocervical Dermoid Cyst by Far Lateral Approach: Case Report and Literature Review

et al. 2018

View full text Add to dashboard Cite

Introduction Intracranial dermoid tumors represent a rare clinical entity that accounts for 0.04 to 0.6% of all intracranial tumors. Their location in the posterior fossa is uncommon. Objectives To report the case of a young woman with a posterior fossa dermoid cyst treated by right far lateral approach. Case Report A 17-year-old woman presenting with swallowing difficulties for 6 weeks was referred for a neurological investigation. A magnetic resonance imaging (MRI) scan showed a hyperintense T1-weighted large expansive lesion occupying the posterior fossa and compressing the anterior face of the brain stem and cerebellum. The patient underwent surgical treatment by right far lateral approach with decompression of vascular and neural structures. The patient presented an uneventful recovery, and was discharged home on the fourth postoperative day without any additional neurological deficits. The anatomopathological analysis confirmed the diagnosis of dermoid cyst. Conclusion The far lateral approach is a safe and feasible route to appropriately treat large posterior fossa dermoid cysts. Decompression of vascular and neural structures is essential to achieve good symptom control.
