“…For patients who have failed surgical treatment or recurrence is documented, radiotherapy has been used as an alternative with fairly good results. The effects of radiotherapy on ET have been assessed in a few case reports,[ 5 7 12 ] and tumor control, as the main goal, can be achieved by this method, with relatively low complications.…”

Background:Epidermoid tumors (ETs) are benign lesions that are treated mainly by means of surgical resection, with overall good results. External beam radiotherapy is an alternative treatment for those recurrent tumors, in which a second surgery might not be the best choice for the patient. A little information exists about the effectiveness of gamma knife radiosurgery for the treatment of newly diagnosed and recurrent ETs. We present three cases of ETs treated with gamma knife radiosurgery.Case Description:Case 1 is a 21-year-old female with an ET located in the left cerebellopontine angle (CPA) with symptoms related to VIII cranial nerve dysfunction. Symptom control was achieved and maintained after single session radiosurgery with gamma knife. Case 2 is a 59-year-old female patient with the history of trigeminal neuralgia secondary to a recurrent ET located in the left CPA. Significant pain improvement was achieved after treatment with gamma knife radiosurgery. Case 3 is a 29-year-old male patient with a CPA ET causing long lasting trigeminal neuralgia, pain relief was achieved in this patient after gamma knife radiosurgery.Conclusion:Long-term symptom relief was achieved in all three cases proving that gamma knife radiosurgery is a good and safe alternative for patients with recurrent or nonsurgically treated ETs.

“…For example, craniopharyngiomas most commonly stem from the infundibulum and are composed of squamous epithelium; however, nearly 60% of these tumors have calcification present [ 5 , 15 ]. In contrast, epidermoid cysts are filled with keratin debris, lipid, and water and appear hypodense on CT [ 6 , 15 ]. While our patient’s neoplasm had a detached fragment that was calcified, these tumors are often present in the pediatric population and present with endocrine symptoms in addition to vision loss [ 5 ].…”

“…While it is still unclear if the degree of resection is predictive of recurrence, it has been suggested that it is most likely the re-accumulation of cyst contents that causes the appearance of symptoms [ 6 ]. As of 2003, the recurrence rate for intracranial epidermoid cysts was stated at 24% [ 7 ].…”

Epidermoid cysts account for a small fraction of intracranial brain tumors, most commonly found in the cerebellopontine angle and parasellar cisterns. Here we present a rare case of an epidermoid cyst located in the suprasellar region, specifically originating from the infundibulum. Only one additional case with an epidermoid cyst originating within the pituitary stalk has been previously reported in the literature. The patient in this case presented with headaches, diplopia and blurred vision without any endocrinopathy. The patient’s pre-operative evaluation was significant for pseudotumor cerebri, hyponatremia, obesity, and a history of smoking; post-operative course was significant for neurogenic diabetes insipidus.

Epidermoid Cyst of the IV Ventricle: Case Report

ResumoOs cistos epidermoides constituem lesões congênitas, benignas e raras, que correspondem a cerca de 0,2% a 1,8% de todos os tumores intracranianos, sendo que em apenas 5% dos casos localizam-se no quarto ventrículo. Apesar de sua gênese na vida intrauterina, são geralmente diagnosticados entre a terceira e quinta década de vida em decorrência de seu padrão de crescimento muito lento. A imagem ponderada pela difusão da ressonância magnética é fundamental para a formulação do diagnóstico. O tratamento ideal consiste no esvaziamento do conteúdo cístico com ressecção completa da cápsula. Neste trabalho, é descrito um caso de uma paciente de 31 anos de idade com síndrome cerebelar, evoluindo com síndrome de hipertensão intracraniana. A sintomatologia era decorrente de hidrocefalia obstrutiva por cisto epidermoide localizado no interior do quarto ventrículo, confirmado pela anatomia patológica. Keywords► epidermoid cyst ► fourth ventricle ► hydrocephalus AbstractEpidermoid cysts constitute congenital, benign and rare lesions, corresponding to approximately 0.2 to 1.8% of all intracranial tumors. Only 5% of cases located in the fourth ventricle. Despite its genesis in intrauterine life, are usually diagnosed between the third and fifth decade of life due to its very slow growth pattern. The imagem weighted by the diffusion of the magnetic resonance is essential to formulation of the diagnosis. The ideal treatment of choice is the empyting of the cystic contente with complete capsule ressection. In this work the case of a 31-year-old female with cerebelar syndrome evolving with intracranial hypertension. The symptomatology was due to obstructive hydrocephaly by an epidermoid cyst located inside the fourth ventricle, confirmed by the pathological anatomy.
