Dermoid Cyst of the Prepontine Cistern and Meckel's Cave: Illustrative Case and Systematic Review

Dermoid cysts are benign, congenital malformations that account for ∼0.5% of intracranial neoplasms. The authors describe a 42-year-old female with a prepontine dermoid cyst who underwent apparent gross total resection (GTR) but experienced cyst recurrence. To date, very few cases of prepontine dermoid cysts have been reported. The prevalent region where these cysts are located can be difficult to determine. In addition, the authors systematically review the literature to characterize the clinical presentation, anatomical distribution, and surgical outcomes of intracranial dermoid cysts. Systematic review. PubMed, Web of Science, and Scopus databases. Extent of resection, symptom improvement, and recurrence rates. A total of 69 patients with intracranial dermoid cysts were identified. Three (4.3%) intracranial dermoid cysts were located in the prepontine cistern. The average age of patients was 33.3 years. The most common presenting symptoms were headache (52.2%) and visual disturbances (33.3%). Intracranial dermoid cysts were distributed similarly throughout the anterior, middle, and posterior cranial fossae (29.0%, 36.2%, and 29.0%, respectively). GTR was achieved in 42.0% of cases. Thirty-four (49.3%) patients experienced symptom resolution. Recurrence rate was 5.8% at a mean follow-up of 2.1 years. Intracranial dermoid cysts most often present as headaches and visual disturbances. Intracranial dermoid cysts were found in the anterior, middle, and posterior cranial fossae at similar frequencies but with clear predilections for the Sylvian fissure, sellar region, and cerebellar vermis. Outcomes following surgical excision of intracranial dermoid cysts are generally favorable despite moderate rates of GTR.

“…Although the location of dermoid cysts in the posterior fossa is not usual, they are located mostly in the midline or around the midline; the location can also occur in the fourth ventricle. 5,6 Logue and Till classified posterior fossa dermoid cysts into four groups, depending on whether they are extradural or intradural, and on the degree of development of the dermal sinus, whether absent, partial, or complete. 7 Infratentorial dermoids are more frequently seen in the first two decades of life.…”

“…They are composed of a capsule containing epidermal elements and dermal derivatives. [1] Moreover, they are thought to originate from the totipotent ectodermal cells, which remain within the developing neural tube between the 3 rd and 5 th weeks of gestation. Dermoid cysts commonly co-exist with a dermal sinus tract in about half of cases.…”

“…Dermoid cysts show various and heterogenous magnetic resonance imaging (MRI) intensity corresponding to the variable contents of the cyst, including fat tissue, keratin debris, hair, skin glands and their secretions and calcifications. [1] However, the presentation of an infected spinal dermoid cyst associated with intramedullary abscess and holocord edema or syrinx, poses a pre-operative diagnostic challenge. We present these cases of infected lumbar dermoid cyst and dermal sinus tract, for its notable location and exceptional radiologic findings.…”

Infected lumbar dermoid cyst mimicking intramedullary spinal cord tumor: Observations and outcomes

et al. 2014

We report two unusual cases of a 17-month-old boy with a previously undiagnosed lumbar dermal sinus tract terminating in an intradural dermoid cyst and holocord edema or syrinx, presenting with paraparesis and sphincter dysfunction secondary to an intramedullary abscess and a 26-month-old boy with a previously undiagnosed lumbar dermal sinus tract terminating in an infected dermoid cyst and intramedullary abscess, presenting with recurrent episodes of meningitis and hydrocephalus. Pre-operative magnetic resonance imaging (MRI) studies in these patients were initially confused for an intramedullary spinal cord tumor; however, the presence of an associated dermal sinus tract made this diagnosis of neoplasm less likely. Total excision of the dermal sinus tract, debulking of the dermoid cyst and drainage of the intramedullary abscess through an L1-L5 osteoplastic laminoplasty and midline myelotomy, followed by long-term antibiotic therapy resulted in a good functional recovery. Post-operative MRI of the spine showed removal of the dermoid cyst, decreased inflammatory granulation tissue and resolution of the holocord edema or syrinx. We also performed a literature review to determine the cumulative experience of management of intramedullary abscess in this rare clinical setting.
