1/234. Cervicomedullary astrocytoma simulating a neuromuscular disorder.

    A 12-year-old male developed progressive proximal upper extremity weakness over a 3- to 4-year period. The clinical findings of proximal upper extremity weakness and atrophy, prominent scapular winging, and no sensory deficits or upper motor neuron signs suggested a neuromuscular disorder. electromyography was consistent with a chronic denervating disorder involving the upper cervical anterior horn cells or their axons. A cervical magnetic resonance image revealed a large intramedullary mass extending from the inferior aspect of the fourth ventricle down to the level of T2. A biopsy of the lesion was consistent with a low-grade astrocytoma.

2/234. Anterior approach to intramedullary hemangioblastoma: case report.

    OBJECTIVE AND IMPORTANCE: Intramedullary spinal cord tumors are generally operated on by using the posterior approach. However, the posterior approach may not be suitable for a tumor in the anterior part of the spinal cord. In this report, we describe a case of a cervical intramedullary tumor that was successfully removed by using the anterior approach. CLINICAL PRESENTATION: A 48-year-old woman presented with lower cranial nerve disturbance and motor weakness of the upper extremities. magnetic resonance imaging revealed a large extensive syrinx and an intramedullary enhanced tumor at the C6 level. The tumor was located at the left of the anterior part of the spinal cord. INTERVENTION: Based on these findings, the anterior approach was used in performing a corpectomy of C5 and C6. The tumor was highly vascular and was resected without resulting in any operative deficits. The pathological diagnosis was hemangioblastoma. CONCLUSION: The present case suggests that the anterior approach is an important option among surgical approaches to the intramedullary tumor in cases in which the tumors are small in size and are located in the anterior part of the cervical cord.

3/234. De novo development of a cavernous malformation of the spinal cord following spinal axis radiation. Case report.

    Analysis of recent reports has suggested that cavernous malformations (CMs) of the brain may have an acquired pathogenesis and a dynamic pathophysiological composition, with documented appearance of new lesions in familial cases and following radiotherapy. The authors report the first case of demonstrated de novo formation of an intramedullary CM following spinal radiation therapy. A 17 year-old boy presented with diabetes insipidus and delayed puberty. Evaluation of endocrine levels revealed hypopituitarism, and magnetic resonance (MR) imaging demonstrated an infundibular mass. The patient underwent a pterional craniotomy and removal of an infundibular germinoma. The MR image of the spine demonstrated normal results. The patient received craniospinal radiation therapy and did well. He presented 5 years later with acute onset of back pain, lower-extremity weakness and numbness, and difficulty with urination. An MR image obtained of the spine revealed an intramedullary T-7 lesion; its signal characteristics were consistent with a CM. The patient was initially managed conservatively but developed progressive myelopathy and partial brown-sequard syndrome. Although he received high-dose steroids and bed rest, his symptoms worsened. He underwent a costotransversectomy and excision of a hemorrhagic vascular lesion via an anterolateral myelotomy. Pathological examination confirmed features of a CM. The patient has done well and was walking without assistance within 4 weeks of surgery. De novo genesis of CMs may be associated with prior radiation therapy to the spinal cord.

4/234. Spinal subarachnoid hemorrhage attributable to schwannoma of the cauda equina.

    BACKGROUND: cauda equina syndrome occurring as a result of spontaneous spinal subarachnoid hemorrhage (SAH) from a spinal tumor is reported to be rare. CASE DESCRIPTION: A 28-year-old woman presented at our clinic with a history of severe back pain for 10 days, progressive paraparesis, and urinary retention. Her physical examination revealed a mass located intradurally at the level of L1-2 and a massive SAH. An L1-L2, laminectomy and a hemilaminectomy from D9 to D12 were performed and the SAH was evacuated and the cord was decompressed. CONCLUSION: At the first year follow-up, her restricted dorsal and plantar flexion continued. Post-gadolinium magnetic resonance imaging revealed no mass.

5/234. spinal cord hamartoma: case report.

    OBJECTIVE AND IMPORTANCE: spinal cord hamartomas are infrequently mentioned in the literature. The authors present a unique report detailing the clinical presentation of a spinal cord hamartoma, with supporting radiographic and pathological data. CLINICAL PRESENTATION: A 26-year-old man presented with progressive right upper extremity weakness. Imaging studies revealed an exophytic cervical spinal cord mass. INTERVENTION: Open biopsy was undertaken and revealed tethering of the lesion to the dura. A pathological examination revealed a spinal cord hamartoma. CONCLUSION: The patient's symptoms improved postoperatively, suggesting that tethering of the spinal cord was responsible for the symptoms. Although unusual, hamartoma should be included in the differential diagnosis of an exophytic spinal cord lesion.

6/234. Excision of spinal tumor in a patient with severe pulmonary dysfunction using combined spinal and epidural anesthesia with two epidural catheters.

    BACKGROUND AND OBJECTIVES: Combined spinal and epidural anesthesia (CSEA) has become common practice. We performed CSEA using two epidural catheters in a 69-year-old female with severe pulmonary dysfunction caused by a diaphragmatic hernia, who underwent surgical excision of a lumbar spinal tumor. methods: Combined spinal and epidural anesthesia was performed using two epidural catheters to minimize postoperative pulmonary complications. One epidural catheter was inserted above the surgical region, at the T11-12 interspace, and another one below the surgical region, via the sacral hiatus. Spinal anesthesia was produced using the L5-S1 interspace and 3 mL 0.5% bupivacaine. oxygen, 3 L/min, was administered through a face mask during surgery. RESULTS: Fifteen minutes after spinal anesthesia, analgesic level was confirmed below T7 using the pinprick method. The patient complained of pain in the surgical region 10 minutes after the dura mater was opened. We injected 5 mL 2% mepivacaine through the upper epidural catheter to relieve the pain. We also injected 10 mL 2% mepivacaine through the lower catheter when she felt pain in the right leg. The perioperative course was uneventful. oxygen saturation was maintained above 95%. CONCLUSIONS: Combined spinal and epidural anesthesia using two epidural catheters was used successfully to excise a spinal tumor in a patient with severe pulmonary dysfunction.

7/234. Solitary fibrous tumor of the spinal cord. Report of a case with scrape cytology.

    BACKGROUND: Solitary fibrous tumor is a rare spindle cell tumor and has been forced at a variety of sites. To the best of our knowledge, only two cases of solitary fibrous tumor arising in the spinal cord have been reported; no cytologic findings were documented. CASE: A 62-year-old male presented with a spinal cord tumor. A scrape smear of the resected tumor revealed naked, spindle-shaped nuclei. Some nuclei were twisted or had long spindles. In the background, abundant, thin and thick collagen fibers were present. Immunohistochemically, the spindle cells were positive for CD34 and negative for S-100 protein and alpha-smooth muscle actin. Histologic diagnosis of the tumor was benign solitary fibrous tumor. CONCLUSION: Our case indicates that solitary fibrous tumor can occur in the spinal cord and should be differentiated from other benign spindle cell tumors, such as meningioma and schwannoma. The key cytologic features of solitary fibrous tumor may be the presence of abundant thin and thick collagen fibers in scrape specimens.

8/234. Renal cell carcinoma: a rare source of cauda equina metastasis. Case report.

    The authors present the case of a patient in whom intradural metastasis from renal cell carcinoma spread to the cauda equina. To the authors' knowledge, this is only the second report of its kind. This male patient had undergone nephrectomy for the treatment of renal cell carcinoma for 5 years and was diagnosed as having metastatic lung disease 1 year prior to admission. The patient presented with lower back pain that radiated to both legs, but he exhibited no sensorimotor deficits. The majority of cauda equina tumors are primary tumors, and metastases are very rare. The literature is reviewed with reference to current molecular genetic paradigms of metastatic renal cell carcinoma.

9/234. Migrated disc in the lumbar spinal canal--case report.

    A 49-year-old man who had complained of back pain for 20 years presented with numbness and pain in his left leg persisting for 6 weeks. magnetic resonance imaging demonstrated a peripherally enhanced intraspinal mass at the L-3 level. The mass was completely removed. The operative and histological findings revealed degenerated disc fragments surrounded by granulation tissue. His symptoms were completely relieved. Migrated disc should be included in the differential diagnosis of patients with a long history of back pain and an intraspinal mass.

10/234. Granulocytic sarcoma of the spine.

    OBJECTIVE: Granulocytic sarcomas (chloromas) are tumors consisting of primitive myeloid cells. They are rare manifestations of acute and chronic leukemias and can occasionally precede the development of systemic disease by weeks to years. Spinal complications of chloromas, such as cord compression secondary to epidural tumor or cauda equina syndrome, have been described but are uncommon. methods: We present eight new cases of spinal chloroma. Three patients displayed significant motor deficit in the form of paraparesis or paraplegia. All patients complained of lower back pain, with other complaints including generalized pain, abdominal pain, numbness and pain in the lower extremities and perianal region, and poor appetite. The average age of the patients was 37 years. Treatment strategies included surgery, chemotherapy, and radiotherapy. Three patients underwent surgical decompression. Six patients received chemotherapy, and six patients received radiotherapy at doses of 2000 to 3000 cGy in up to 30 fractions. RESULTS: Patient survival ranged from 18 days to 9.5 years after diagnosis. A review of the previously reported cases of granulocytic sarcoma in addition to our new cases reveals that the most effective treatment is multimodality therapy coupled with early diagnosis. CONCLUSION: Increased awareness of this entity will facilitate early diagnosis and minimize potentially preventable neurological morbidity.
