A RARE CASE OF RHABDOMYOSARCOMA PRESENTING AS AN INTRADURAL SPINAL TUMOR

Vol. 01, Issue 04, pp.133-139, July, 2020 Available online at http://www.scienceijsar.com

International Journal of Science Academic Research

Abstract Spinal cord compression is a very serious complication of malignancy in adults. A Sarcoma presenting with an epiduralmass, and spinal cord compression is very rare. We report a case of a 29 year old female patient who presented to us with para-spinal and epidural rhabdomyosarcoma (RMS) causingspinal cord compression and a complete brachial plexopathy. She came with a 15 month history of right upper limb pain and weakness, neck mass associated with neck pain and a 2 week history of bilateral lower limb weakness associated with urine and stool incontinence. Imaging studies showed a large lobulated intra-dural and extra-medullary enhancing dumbbell-shaped tumor at C6/C7 levels compressing the spinal cord at that level .There was a right supraclavicular mass with central necrosis and involving the exiting regions of the spine. There was a syrinx in the spinal cord above the level of the lession extending up-to C2. The patient was taken for laminectomy and durotomy and excision of the intra-dural portion of the tumor. Histology confirmed the diagnosis of rhabdomyosarcoma. After surgery there was improvement in signs and symptoms. Unfortunately she died while still waiting for the second stage of the operation to excise the extra-spinal tumor component. Keywords: Rhabdomyosarcoma, Extradural Spinal Tumor, Dumbbell, Spinal Cord Compression INTRODUCTION Rhabdomyosarcoma is a highly aggressive and rapidly growing sarcoma with skeletal muscle origin that occasionally appears in the spinal epidural space (Kim et al., 2000). This report deals with a case of rhabdomyosarcoma in the upper thoracic spine with a particular interest, not only for the rarity of type but also the location and complications of this tumor. Spinal tumors comprise 15% of all CNS tumors. Their annual incidence is 2-10 per 100000. Ninety percent of these patients are older than 20 years. Most common spinal tumor location is extradural (55-60%), where cancer metastasis to spine leads the way. Primary vertebral bone tumors are less frequent extradural spinal tumors. Extramedullary, intra-dural spinal tumors (EISTs) are rare. They comprise about 40-45% of all spinal tumors. The fourth to sixth decades of life represent the peak incidence of occurrence. Men and women are equally affected. Spinal cord compression can occur in rhabdomyosarcoma. It can be due to direct spread of the tumor, spread to the epidural space by infiltration of the vertebral foramina or metastatic vertebral bone disease with cord compression. Most intra-dural extramedullary tumors are benign, and they exhibit no specific symptoms. Radicular pain and worsening sensory and motor loss are common manifestations. Patients may have bladder or bowel complaints. Therefore, most of the patients are wrongly diagnosed with cervical spondylopathy or intervertebral disk herniation. MRI is very crucial to confirm the diagnosis of intra-dural extramedullary tumors. Once the diagnosis is confirmed, the best treatment for nonmalignant intra-dural extramedullary tumor is surgery. The goal of surgery is complete surgical resection while preserving spinal stability, without worsening the preoperative neurological status. *Corresponding Author: Kelvin Nemayire, Department of Neurosurgery, University of Zimbabwe, Harare, Zimbabwe. CASE REPORT We report a case of a 29 year old female patient who presented to us with a 15 month history of right upper limb pain and weakness, neck mass associated with neck pain and a 2 week history of bilateral lower limb weakness associated with urine and stool incontinence. She was previously well until about a year and three months prior when she started experiencing right sided neck pain mainly at night .The pain would radiate to her right upper limb particularly her right thumb and middle finger .This was then accompanied by progressive numbness and weakness of the same limb until about 2 months after onset of symptoms that she became completely paralysed in that limb. This was followed by gradual onset painless weakness and paraesthesia of the left upper limb.2 weeks prior to presentation she developed lower limb paraesthesia and weakness associated with bowel and bladder dysfunction (incontinence). She developed dyspnea as well around the same time. There was no history of trauma or any known malignancies. She did not have any history of TB contact and was HIV negative. On examination patient was ill looking, with a moderate respiratory distress (respiratory rate of 25 breaths per minute, intercostal and supraclavicular recessions), paradoxical breathing. She was pale and wasted. There was a right sided mildly tender supraclavicular firm mass which was 8 x 6 cm in its widest diameters, immobile and attached to underlying structures. Her LOC was 15/15,all cranial nerves were intact and her eye examination was unremarkable. Upper limb examination Right upper limb muscles were wasted and had visible unprovoked fasciculations. Sensory level was C5 on the right and C6 on the left. There was arreflexia in the right upper limb and hyperreflexia in the left upper limb. Propriocepti
