Omaya insertion followed by ventricular peritoneal shunt in case of epidermoid cyst of central nervous system: A case series

Intracranial epidermoid cyst originating from abnormal migration of neuroectodermal cells during embryogenesis. It is a slow-growing tumor commonly found in cerebellopontine angle, fourth ventricle, and sellar/parasellar region. This is a case series of five cases to know the effectiveness of Omaya in pre-operative and early post-operative period followed by ventriculoperitoneal shunt after 2 weeks. This is a prospective observational study done in premier institute of central India from April 2023 to April 2024. A total five cases of different age groups and clinical presentations are included. There is no ventriculoperitoneal shunt blockage when it was followed by early pre- and post-operative period large reservoir Omaya insertion.
