  • Spinal meningiomas located purely in the extradural space are rare, and they may easily be confused with malignant neoplasm. We report an unusual case of a purely extradural spinal meningioma mimcking metestatic neoplasm. A 38-year-old woman had neck pain and left side weakness. MRI scan revealed extradural spinal mass. Preoperative and intraoperative diagnosis was metastatic carcinoma, but permanent diagnosis was extradural meningioma.

  • Tumors of the central nervous system are common in the pediatric population and constitute the second most prevalent tumor type in children. Within this group, spinal cord tumors are relatively rare and account for 1 to 10% of all pediatric central nervous system tumors. We describe a very rare case of an intradural extramedullary spinal cord tumor with a subcutaneous mass and discuss its clinical presentation, pathogenesis, and treatment. A male infant was delivered normally, with uneventful development. At 16 days post-delivery, his family took him to a pediatrician because of a mass on his upper back. Magnetic resonance imaging of the thoracic spine revealed a well-demarcated soft-tissue mass with central cystic change or necrosis at the subcutaneous layer of the posterior back (T2-7 level). Another mass was found with a fat component at the spinal canal of the T1-3 level, which was intradural extramedullary space. After six weeks, the spinal cord tumor and subcutaneous mass were grossly total resected; pathologic findings indicated an atypical myxoid spindle cell neoplasm, possibly nerve sheath in type. The final diagnosis of the mass was an atypical myxoid spindle cell neoplasm. The postoperative course was uneventful, and the patient was discharged after nine days without any neurological deficit. We report a rare case of an intradural extramedullary spinal tumor with subcutaneous mass in a neonate. It is necessary to monitor the patient's status by examining consecutive radiologic images, and the symptoms and neurological changes should be observed strictly during long-term follow-up.

  • While syringomyelia is not a rare spinal disorder, syringomyelia associated with a spinal arachnoid cyst is very unusual. Here, we report a 62-year-old man who suffered from gait disturbance and numbness of bilateral lower extremities. Spinal magnetic resonance imaging (MRI) showed the presence of a spinal arachnoid cyst between the 7th cervical and 3rd thoracic vertebral segment and syringomyelia extending between the 6th cervical and 1st thoracic vertebral segment. The cyst had compressed the spinal cord anteriorly. Syringomyelia usually results from lesions that partially obstruct cerebrospinal fluid flow. Therefore, we concluded that the spinal arachnoid cyst was causing the syringomyelia. After simple excision of the arachnoid cyst, the symptoms were relieved. A follow-up MRI demonstrated that the syringomyelia had significantly decreased in size after removal of the arachnoid cyst. This report presents an unusual case of gait disturbance caused by syringomyelia associated with a spinal arachnoid cyst.

  • Solitary fibrous tumor is rare benign mesenchymal neoplasm. The spinal solitary fibrous tumor is extremely rare. The authors experienced a case of intramedullary solitary fibrous tumor of cervicothoracic spinal cord in a 48-year-old man with right lower extremity sensory disturbance. Spinal MRI showed intradural mass lesion in the level of C7-T1, the margin between the spinal cord and tumor was not clear on MRI. A Left unilateral laminectomy and mass removal was performed. Intra operative finding, the tumor boundary was unclear from spinal cord and it had intramedullary and extramedullary portion. After surgery, patient had good recovery and had uneventful prognosis. Follow up spinal MRI showed no recurrence of tumor.

  • Intradural extramedullary hemangioblastoma of the spinal cord is uncommon tumor. Symptom onset is typically in the forth decade. Complete excision offers the best chance for cure. We report a case of extramedullary hemangioblastoma of the spinal cord in old age. A 76 -year old man presented with 1 month history of paraparesis. Multiple enhancing lower thoracic and lumbar spinal masses were seen on magnetic resonance imaging(MRI). Surgical exploration for symptomatic lesion revealed intradural-extramedullary mass, which had hypervascularity. The excised spinal masses were diagnosed as hemangioblastoma. Postoperative course was uneventful and symptoms improved gradually.

  • Primary central nervous system (CNS) melanoma is a rare condition that accounts for only 1% of all melanomas. A 34-year-old Korean female presented with a two-month history of progressive weakness in both legs. Spinal magnetic resonance image (MRI) revealed a spinal cord tumor at the level of T4, which was hyperintense on T1-weighted imaging and hypointense on T2-weighted imaging. The intradural and extramedullary tumor was completely resected and diagnosed as melanoma. There were no metastatic lesions. At three years after surgery, the patient is still alive, with no evidence of tumor recurrence. We present the details of this case along with a comprehensive review of spinal cord melanoma.

  • Dumbbell neurogenic tumor is a rare disease, arising about 10 % of mediastinal neurogenic tumor. We report a 31 year old man who was suffered from paresthesia and weakness of lower extremities for about 8 months. Chest x-rays revealed a dumbbell shaped mass shadow in left lower posterior mediastinum. MRI demonstrated a well defined dumbbell shaped mass in the mediastinum of T7 level, including spinal cord compression by the extended tumor into the spinal canal and enlarged intervertebral foramen. The patient underwent one-stage combined resection of the tumor through the thoracotomy and laminectomy, simultaneously. The tumor was confirmed as neurilemmoma. The postoperative course was smooth and uneventful.

  • Spinal intradural extramedullary teratoma is a rare condition that develops more commonly in children than in adults and may be associated with spinal dysraphism. We report a rare case of adult-onset intradural extramedullary teratoma in the thoracolumbar spinal cord with no evidence of spinal dysraphism and without the history of prior spinal surgery. The patient was a 38-year-old male whose chief complaint was urinary incontinence. X-ray images of the thoracolumbar spine showed the widening of the interpedicular distance and posterior marginal erosion of the vertebral bodies and pedicles at the T11, T12, and L1 level. Magnetic resonance imagings of the lumbar spine showed a lobulated inhomogeneous high signal intradural mass ($87{\times}29{\times}20mm$) between T11 and L1 and a high signal fluid collection at the T11 level. Laminectomy of the T11- L1 region was performed, and the mass was subtotally excised. The resected tumor was histopathologically diagnosed as a mature cystic teratoma. The patient's symptom of urinary incontinence was improved following the surgery.

  • An intramedullary spinal cord metastasis (ISCM) rarely develops in systemic cancer but is indicative of a poor prognosis. A 56-year-old man was admitted due to weakness of the lower extremities. He had received radiotherapy 3 months prior for a brain metastasis that had developed 1 year after achieving a complete response from chemotherapy for extended stage small cell lung cancer. Although the brain lesion had improved partially, ISCM from the cervical to lumbar-sacral spinal cords, which was accompanied by a leptomeningeal dissemination, was diagnosed based on magnetic resonance imaging of the spine and cerebrospinal fluid cytology. Finally, he died of sudden cardiac arrest during treatment. This is the first case of ISCM involving the whole spinal segments. Physicians should be aware of the subsequent development of ISCM in lung cancer patients with a previously known brain metastasis who present with new neurological symptoms.

  • Angiolipomas in the lumbar spinal region are extremely rare. The present report describes the identification of such a tumor and its removal, and discusses the tumor characteristics and prognosis. A 74-year-old woman was presented with a 5-month history of lower back pain. Severe radiculopathy was experienced in the left leg for 5 days prior to the presentation, and there were no neurological deficits. Magnetic resonance (MR) images showed an approximately 3.5 cm heterogeneously enhanced and elongated mass at the left L5-S1 level. A portion of the mass appeared with high signal intensity on T2-weighted MR images, with low signal intensity on T1-weighted images, and with high signal intensity on T1 fat suppression enhancement images. Resection of the tumor was approached via an L5 and S1 laminectomy. A fibrous sticky yellowish hypervascular tumor was identified. Histological study revealed the tumor as an angiolipoma. Symptoms were relieved after tumor excision, and there were no neurological sequelae. Although extremely rare, lumbar epidural angiolipoma should be considered in the differential diagnosis of lumbar spinal epidural lesions. The prognosis after surgical management of this lesion is favorable.
