ABSTRACT
INTRODUCTION: Intraspinal Epidermoid Cyst (IEC) is a very-rare, yet one of the most benign tumors of the Central Nervous System (CNS). Very few cases of IEC were reported world-wide. Presentations depend on the location of the tumor with pain being the most common presenting symptom. CASE PRESENTATION: A-35-year-old patient presented to the neurosurgical department for a regular follow up. Her history dates back to four years ago, when she first presented with back pain, which was later accompanied with fecal and urinary incontinence. Magnetic Resonance Imaging (MRI) showed a tumor at the level of L4-L5 which was surgically removed. Three years later, the patient presented to the clinic with similar symptoms. A repeat MRI showed a mass at L4-L5, which was surgically removed. Histological findings of both surgeries showed findings consistent with IEC. Currently the patient has no complaints. CLINICAL DISCUSSION: IEC has various presentations. Our case presented with back pain, and urinary and fecal incontinence. Diagnosis depends on imaging and histology. MRI is the imaging modality of choice for those tumors in the CNS. Surgical removal is associated with high recurrence as a result of the suboptimal resection due to the strong adhesions between the capsule and the spinal cord. CONCLUSION: Pain is the most common presenting symptom for IEC. Adjuvant radiotherapy, which should be implemented in the standard of care, is associated with a lesser degree of recurrence, in addition to regular follow-ups.
