Totally cystic intradural extramedullary lesions are uncommon and form a different spectrum of conditions as compared to the commonly seen intradural extramedullary tumors. Spinal schwannomas are benign tumors arising from spinal nerve root sheaths and are the most common intradural extramedullary spinal tumors. Though cystic changes in schwannomas are well described, most spinal schwannomas ar...

Hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). Their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).However, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. Hereby, authors report a w...

A 16-year-old girl had progressive neck pain and weakness in the left hand. MR images showed a dumbbell-shaped spinal tumor with a prominently enhancing intradural component and a minimally enhancing extradural component. Pathologic examination revealed a meningioma with an intradural transitional component and an extradural syncytial component. The tumor showed no significant cystic change or ...

We report a case of the coexistence of different spinal tumors at the same level of the cervical spine, without neurofibromatosis (NF), which was successfully treated with surgery. A 72-year-old female presented with right upper-limb clumsiness and weakness. Magnetic resonance imaging revealed an intradural, extramedullary tumor mass at the right C3-4 level with extradural extension into the in...

our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

Background & Importance: Cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. We report a case of the spinal intradural Cavernous angiomas of the lumbar spine. Case Presentation: A 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. ...

Conventional laminectomy is the most popular technique for the complete removal of intradural spinal tumors. In particular, the central portion intramedullary tumor and large intradural extramedullary tumor often require a total laminectomy for the midline myelotomy, sufficient decompression, and adequate visualization. However, this technique has the disadvantages of a wide incision, extensive...

Intradural extramedullary spinal ependymomas are extremely rare. Herein, we describe a lesion-type spinal ependymoma that followed a malignant course, and discuss its clinical presentation, etiopathogenesis, and treatment. We present a patient who was diagnosed with an intradural extramedullary spinal tumor at T4-T6. The patient underwent gross total resection of the tumor without damage to the...

OBJECTIVES To describe a case of extramedullary-intradural metastases causing cauda equina syndrome (CES) as the primary syndrome of lung cancer, and to review the pertinent medical literature. SUMMARY OF BACKGROUND DATA Intradural spinal metastasis is rare, accounting for 6% of all spinal metastases. Of all primary lesion types, lung carcinoma is about 40-85%. Extramedullary-intradural metas...

BACKGROUND We wanted to investigate the results of surgical treatment and analyze the factors that have an influence on the neurologic symptoms and prognosis of spinal intradural extramedullary (IDEM) tumors. METHODS The spinal IDEM tumor patients (11 cases) who had been treated by surgical excision and who were followed up more than 1 year were retrospectively analyzed. Pain was evaluated by...
