“…Myxopapillary ependymoma can dilate the spinal canal and cause deformation of the vertebral bodies, and its growth can be seen on conventional X-ray [ 10 , 11 ]. Typical MRI findings are well-circumscribed intradural tumors, round or elongated in shape, lobulated in outline, usually occupying more than 1 vertebral body height level.…”

Patient: Male, 44-year-old Final Diagnosis: Myxopapillary ependymoma Symptoms: Low back pain Clinical Procedure: Laminecromy • laminoplasty • radiotherapy Specialty: Neurology • Neurosurgery • Oncology • Pathology • Radiology Objective: Rare disease Background: Myxopapillary ependymoma is a rare type of slow-growing tumor that mainly occurs in the spinal cord, particularly in the region of the conus medullaris and the cauda equina. It originates from the ependymal glial cells found in the filum terminale. Case Report: We present a clinical case of a 44-year-old male patient who presented with symptoms of non-specific pain in the lower back persisting for the past 2 years. He did not report any specific neurological deficits or radicular symptoms. Unenhanced MRI of the lumbar spine showed a giant intradural, extramedullary, heterogenous, expansive tumor at the level L1-S4 with erosion of the sacral bone and invasion of presacral tissue. Based on its characteristic localization and growth pattern, suspicion arose for myxopapillary ependymoma. Biopsy confirmed the initial diagnosis. Partial resection of the tumor with laminectomy and laminoplasty was deemed necessary. Preoperative neural axis MRI showed contrast-enhancing lesions in the cerebellum and the cervical and thoracic spine; therefore, adjuvant radiation therapy was administered. Following the surgery, the patient experienced intermittent episodes of neurological deficits and required physiotherapy. Control MRI a year after the operation showed tumor growth and more metastases along the neural axis. Conclusions: Complete surgical excision of the tumor is the preferred treatment approach, but there is a risk of recurrence even after total excision, so radiotherapy is recommended to minimize the risk of recurrence. Prior to surgery, it is essential to conduct MRI/PET/CT of the head and spine to assess the possibility of metastases.

CASE DESCRIPTION A 3-year-old 31.1-kg castrated male mixed-breed dog was evaluated because of a 1- to 2-week history of paraparesis, knuckling of the hind feet, and difficulty posturing to urinate or defecate. CLINICAL FINDINGS The dog was paraparetic but weakly ambulatory with a kyphotic posture, a mildly decreased patellar reflex in the right pelvic limb, increased tone in both pelvic limbs, and marked hyperesthesia on paraspinal palpation of the lumbar region. The urinary bladder was enlarged and firm on palpation. Neuroanatomic findings were primarily consistent with localization to the T3-L3 spinal cord segments. Magenetic resonance imaging of the thoracolumbar spinal column revealed a discrete intramedullary spinal cord mass from the cranial aspect of L4 to the middle of L5. The mass was sampled by fine-needle aspiration, and on cytologic evaluation, the suspected diagnosis was an ependymoma. TREATMENT AND OUTCOME Owing to poor prognosis and limited treatment options, the owner elected euthanasia. Postmortem examination of the spinal cord and histologic findings for samples of the mass supported a likely diagnosis of ependymoma. CLINICAL RELEVANCE Ependymoma is a rare neoplasm in dogs but should be considered in young patients with evidence of a tumor in the CNS. Fine-needle aspiration of the spinal cord mass was possible in the dog of this report, and the cytologic findings provided useful diagnostic information.
