| Summary: | <p>Abstract</p> <p>Introduction</p> <p>The authors report a rare case of primary spinal ependymomatosis in a young adult man. Multiple primary ependymomatous lesions were seen on magnetic resonance imaging and no anaplasia was identified on the surgical-pathological analysis. The aetio-pathological mechanism and surgical significance of this rare occurrence is discussed.</p> <p>Case presentation</p> <p>A 26-year-old man of Polish origin presented with a ten-day history of pain in the left leg and lower back. This was followed by difficulty in urinating and a decrease in sensation in both legs. Examination revealed pyramidal signs and mild weakness in both lower limbs. He had early sphincter involvement requiring catheterization. Magnetic resonance imaging of the brain was normal. However, that of the spinal cord revealed multiple intradural spinal lesions, both intra- and extramedullary, extending from the cervical cord down to the cauda equina roots. T12-L1 laminectomy was performed. Multiple intradural, extra- and intra-medullary tumors were seen. After the operation, the patient deteriorated with a sensory level at T4. Post-operative cranio-spinal radiotherapy was administered but there was no clinical improvement in the lower limbs.</p> <p>Conclusion</p> <p>Primary spinal ependymomatosis is a rare phenomenon involving multiple spinal segments in the absence of a primary intracranial tumor. Radical excision is unrealistic in this condition. Biopsy followed by radiotherapy is the preferred method of treatment.</p>
