Intracranial epidermoid tumors are rare, potentially curable, benign lesions that are sometimes associated with perioperative complications, and tend to recur if not completely removed. Histologically benign epidermoid tumors may also develop into highly malignant tumors. This study evaluated on 28 cases of intracranial epidermoid tumor treated over a 13-year period by radical resection with microneurosurgical techniques. The majority of patients underwent computed tomography and/or magnetic resonance imaging within the first 24 hours postoperatively to confirm the results of surgery. Radical surgical resection was achieved in 21 of the 28 cases, and there was no operative mortality. The most common postoperative complication was transient paresis of various cranial nerves. During a mean follow up of 6 years, only one tumor became malignant. Radical surgical resection should be the goal in treating these benign lesions, but if not possible, every effort should be made to minimize the amount of tumor tissue that remains.

“…Early detection through routine MR imaging may improve surgical outcome in recurrent cases, since the tumors are more amenable to surgery at this stage. 4,9,22,23,29,35) In conclusion, intracranial epidermoid tumors should be treated with radical surgical resection. Since these are benign tumors, complete removal should be the goal.…”

Object Epidermoid tumors are benign lesions representing 1% of all intracranial tumors. There have been few pediatric series of intracranial epidermoid tumors reported previously. The authors present their experience in the management of these lesions. Methods The neurosurgical database at the Hospital for Sick Children was searched for children with surgically managed intracranial epidermoid tumors. The patients' charts were reviewed for demographic data, details of clinical presentation, surgical therapy, and follow-up. Ethics board approval was obtained for this study. Results Seven children, all girls, were identified who met the inclusion criteria between 1980 and 2007. The average age at surgery was 11.2 years (range 8–15 years), and the mean maximal tumor diameter was 2.1 cm. Headache was the most common presenting symptom, and 1 tumor was found incidentally. Most patients had normal neurological examinations, but meningism was found in 2 cases. There were 3 cerebellopontine angle lesions, 1 pontomedullary lesion, and 3 supratentorial tumors. Hydrocephalus developed in 1 patient after aseptic meningitis, and she underwent shunt placement. There were no operative deaths. Complete resection could be performed in 2 patients. One patient experienced a small recurrence that did not require a repeated operation, while 1 subtotally resected lesion recurred and the patient underwent a second operation. Conclusions Intracranial epidermoid tumors are rare in the pediatric population. Total resection is desirable to minimize the risk of postoperative aseptic meningitis, hydrocephalus, and tumor recurrence. Aggressive neurosurgical resection may be associated with cranial nerve or ischemic deficits, however. In these cases, neurosurgical judgment at the time of surgery is warranted to ensure maximum resection while minimizing postoperative neurological deficits.

A total of 40 patients with epidermoid cysts of the cerebellopontine angle (CPA) underwent surgery between 1980 and 1993. Total resection was achieved in 30 cases (75%); in 10 cases (25%) parts of the cyst capsule were left because they adhered to the brainstem and vascular structures of the CPA. One patient with very large bilateral epidermoid cysts, who underwent complete bilateral resection in one stage, died of pulmonary aspiration and infection. As of their latest clinical and radiological follow-up examinations (mean 5.7 years), 93% of the patients are able to lead useful lives. Three cases of cyst regrowth have been observed thus far. Modern radiological tools and microsurgery techniques have considerably improved the completeness of cyst resection and reduced postoperative mortality and morbidity rates; however, there still are some cases in which complete resection is impossible without producing severe neurological deficits.
