Spinal intramedullary epidermoid cysts: Three case presentations and literature review

Abstract

Background: True intramedullary epidermoid cysts (IECs) not associated with congenital anomalies or previous spinal procedures are extremely rare. In a review of the literature since 1992, only 29 such cases have been reported. Here, we add three new cases in this category. Case Description: Three adults presented with spastic paraparesis attributed to thoracic IECs. Gross total microsurgical removal was achieved in two cases, while one case was a partial resection due to capsular adherence to the cord. In all three cases, patients sustained complete recoveries of neurological function and remained symptom free for an average of 5 years follow-up. Conclusion: IECs are rare lesions; here, the three located in the thoracic spine, contributed to slow, progressive spastic paraparesis with/without incontinence, and resolved following total (2 patients) and partial (1 patient) resection.

Intramedullary mature teratoma with an exophytic component in an adult: Report of a case and literature review

“…[1][2][3][4][5][6]9,10] e distinction between epidermoid cysts and juxtamedullary lipomas with IMMTs may prove difficult. [7,8] Treatment e best treatment for IMMTs is gross total surgical excision (e.g., found in 27 cases from the literature). Intimate adherence of tumor to the spinal cord parenchyma may preclude total removal (e.g., showing in 25 cases).…”

“…Preoperative high-resolution MRI allows better preoperative planning. [1][2][3][4][5][6] Intraoperative use of neurophysiological monitoring helps the surgeons to preserve patient neurological function, making resection safer and more accurate. Gross-total resection was the goal of surgery to avoid the risk of recurrence and aseptic meningitis.…”
