Pineal epidermoid cyst: case report and review of the literature

Abstract

Intracranial epidermoid cysts are one of the rare tumors of all intracranial tumors. They represent 0,2 to 1% of intracranial tumors and 7% of tumors in the cerebellopontine angle. The pineal region is exceptionally subject to such kind of tumor. Cushing was the first to report the pineal localization of the epidermoid cyst in 1928. Up to now, 85 cases of pineal epidermoid cyst were cited in the literature. We report a clinical case concerning a 45 years old man who presented an intracranial hypertension during 18 months. The clinical examination found a hemiparesis with a facial hypoesthesis. The MRI showed a process of the pineal region. The patient underwent a surgery with a large resection. The histological examination confirms the epidermoid cyst. Many approaches were described in the literature. The outcome is related to this localization.

An Unusual Dermoid Cyst of the Pineal Region: Case report in a Child

“…In a reported series of epidermoid cysts, in some cases, the surgeon preferred to intentionally leave in situ fragments of the adherent capsule to the deep veins of this region to avoid any risk. 14,15 Operation approaches are more studied on epidermoid cysts than in dermoid cysts, considering their higher prevalence. 14 The prognosis of patients with dermoid cysts appears appropriate after resection.…”

“…14,15 Operation approaches are more studied on epidermoid cysts than in dermoid cysts, considering their higher prevalence. 14 The prognosis of patients with dermoid cysts appears appropriate after resection. 9 In this case, the 4-and 8-month outcome after total resection is favorable.…”

Giant occipital intradiploic epidermoid cyst

“…Intracranial epidermoid cysts are well-circumscribed lesions, which most often occur within the diploe, in the parasellar region, Sylvian fissure, cerebellopontine angle, posterior fossa, and fourth ventricle. [ 8 ] Intradiploic epidermoid cysts are much less common than intradural lesions. Ectodermal inclusion cysts have a thin capsule of stratified squamous epithelium filled by keratin, cellular debris, and cholesterol.…”

Unilateral lateral rectus palsy-an unusual presentation of pineal epidermoid cyst

“…Epidermoid cysts are a group of slow growing intracranial tumors representing approximately 1% of all central nervous system tumors. Furthermore, pineal location of epidermoid cyst is extremely rare [ 1 , 2 ]. Headache and ataxia are the common modes of presentation [ 2 ].…”

“…Furthermore, pineal location of epidermoid cyst is extremely rare [ 1 , 2 ]. Headache and ataxia are the common modes of presentation [ 2 ]. We report an unusual presentation of this rare tumor, diplopia and unilateral lateral rectus palsy, in an adolescent boy.…”
