Ruptured dermoid cyst in the Meckel’s cave presenting with trigeminal neuralgia in a pediatric patient: a case report

Cranial Neuralgias in Children and Adolescents A review of the literature

“…CPA lesions are overall uncommon, as seen in one retrospective report of 36 CPA lesions out of 819 cases of TN (4.4%) with only one under age 18 (0.12%) [22]. Additional SOL cases include Burkitt lymphoma [29], CPA arachnoid cyst [30], choristoma [31], capillary telangiectasia [9], embryonal rhabdosarcoma [32], ruptured dermoid cyst [33], anterior inferior cerebellar artery loop [34], and pilomyxoid astrocytoma [35]. There have been two reported cases of AVM [36,37].…”

Intracranial Dermoid Cyst in the Posterior Fossa: A Case Report

“…These lesions often originate from ectopic epithelium sequestered inside the neural tube during embryogenesis (3)(4)(5)(6)(7)(8). They have strong predilections for the Sylvian fissure, sellar region as well as cerebellar vermis although isolated cases have been found in the anterior, middle, and posterior cranial fossa at comparable rates (2,3,9,10). Currently only few cases of dermoid cysts have been reported at posterior fossa (2,11).…”

“…The cardinal symptomatology of intracranial dermoid cysts are headaches and visual disturbances (3,4,9,10). Radiologically, intracranial dermoid cysts characteristically present as non-enhancing low-density masses on Computer tomographic (CT) scan as well as hyperintense on T1-weighted magnetic resonance imaging (MRI) sequences with inconsistent signals on T2-weighted sequences (5,12).…”
