“…The wall of intracranial dermoid cyst is often depicted with thick, stratified squamous epithelium capsule that encloses dermal elements like sebaceous glands, sweat glands as well as hair follicles (3)(4)(5)(6)(7)(8)13). In almost all the cases reported in literature, the features above, most specially the presence of hair follicles were detected during histopathology evaluation (3,5).…”

“…These lesions are congenital malformations that account for about 0.5% of all intracranial neoplasms (3). 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).…”

“…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).…”

Introduction: Intracranial dermoid cysts are benign, ectopic squamous epithelial cysts often compose of dermal structures like hair follicles, sweat glands as well as sebaceous glands. This lesions constitutes about 0.5% of all intracranial neoplasms. Thus, the occurrence of a dermoid cyst in the posterior fossa is very rare. We report a rare case of intracranial dermoid cyst in posterior cranial fossa. Case Presentation: Our first case was a 32 years old woman who presented with headaches and dizziness with no nausea, vomiting or fever. CT scan revealed a mass at occipital cistern consistent with a cystic lesion. MRI also revealed an irregular lesion in the posterior part of the medulla oblongata with enhanced edges signifying calcifications. We attained total resection of the tumor in a piece meal approach via surgery. Histopathology confirmed dermoid cyst. Two years follow-up revealed no recurrence of the lesion and no neurological deficits. Conclusion: We advocate that, the goal in surgical decision-making should be safe and total resection while monitoring the cranial nerves with electromyographic and auditory brainstem responses.
