Epidermoid tumors of the fourth ventricle

Clinical characteristics and diagnostic imaging of epidermoid tumors

“…22,36,39 Epidermoid cysts in the posterior fossa most commonly present with cranial nerve involvement and gait ataxia. 14,22,43 Common initial symptoms of cysts found in the 4th ventricle include headache, vertigo and gait disturbance. Diplopia, dysphagia, and hoarseness may present at a later stage when the cranial nerves become involved.…”

Reversible Bilateral Vestibular Impairment Caused by Fourth Ventricle Epidermoid Tumor-Case Report-

“…Epidermoid tumors of the fourth ventricle present with various symptoms including headache, 3,11) gait ataxia, 3,9,13,20) and vertigo 9,20) in the initial stage and cranial nerve symptoms including diplopia, dysphagia, and hoarseness at a later stage. 9,12,20) In our case, the clinical symptoms consisted of headache and vertigo caused by bilateral vestibular impairment.…”

“…1,21) Epidermoid tumors of the fourth ventricle account for between 5% and 31.4% of all intracranial epidermoid tumors. 7,9,13,15,16,19,20) The clinical symptoms vary depending on the location, extension, and degree of adhesion to vital structures. Headache, 3,11) gait ataxia, 3,9,13,20) and vertigo 6,14) are common initial symptoms of epidermoid tumors of the fourth ventricle.…”

Headache, 3,11) gait ataxia, 3,9,13,20) and vertigo 6,14) are common initial symptoms of epidermoid tumors of the fourth ventricle. Here, we describe a case of epidermoid tumor of the fourth ventricle manifesting as vertigo caused by bilateral vestibular impairment, which completely disappeared postoperatively.…”

“…Epidermoids of the brain are rare tumors, accounting for approximately 1% of all brain tumors, [1][2][3]13,22) and are usually located in the cerebellopontine angle 1,5,10,14,15,17,18) and parasellar region. 1,21) Epidermoid tumors of the fourth ventricle account for between 5% and 31.4% of all intracranial epidermoid tumors.…”
