Ancient schwannoma of the conus medullaris.
Cystic spinal or ancient schwannoma is a rare form of intradural tumour especially in the conus medullaris region. Due to its indolent behavior and benign course, the diagnosis of schwannoma is always a challenge and the imaging findings can be misleading. Our patient presented with chronic mild sciatica pain without any other neurological symptom. MRI of the spine showed intradural tumour located at the conus medullaris region with nerves compression and was reported as ependymoma. L3-L5 laminectomy and total excision of tumour was performed without any neurological complication. We concluded that ancient schwannoma of the conus medullaris is a rare benign tumour that can present with minimal non-specific neurological symptom that lead to misdiagnosis. Radical tumour excision is safe with an excellent outcome.
