Meningeal solitary fibrous tumor (SFT) is a rare tumor and is different from fibroblastic meningiomas (FM) and hemangiopericytoma (HPC). SFTs account for 0.09% of all meningeal tumors.[1-3] Compared to meningiomas the SFTs show a predilection for the posterior fossa and spine.[1,2] Most of these tumors are benign, however, local recurrence have been reported.[3] Gengler and Guillou[4] in a revi...

BACKGROUND We wanted to investigate the leading cause of failed vertebroplasty or kyphoplasty. METHODS Twelve patients (10 females and 2 males) who underwent revision surgery after vertebroplasty or kyphoplasty were included. In 4 cases, vertebroplasty was done for two or more levels. Six cases with kyphoplasty were included. Through the retrospective review of the radiographic studies and me...

The central and peripheral motor pathways serving striated sphincter muscle function were studied using cortical and lumbar transcutaneous electrical stimulation, pudendal nerve stimulation and sphincter electromyography in 23 patients with multiple sclerosis (MS), and sphincter disturbance, including incontinence of urine or faeces, urinary voiding dysfunction, or constipation. The central mot...

With great interest, we read the study of Line Dussourd et al. concluding that ultrasonography allows better identification of anatomical structures before performing a lumbar puncture. We cannot concur with the conclusions of the study because the authors did not visualize the conus medullaris directly, nor did they assess the individual intervertebral levels. In our commentary, we make some s...

Hemangioblastomas are uncommon lesions that represent nearly 4% of the tumors of the spinal cord. Three fourths of them are sporadic, and the remainder are components of von Hippel Lindau (VHL) disease.1,2 They are mostly found in the cerebellum, although they can develop in the brain stem or spinal cord; of the latter, they are only rarely located in the filum terminale.3 The filum terminale i...

A 41-year-old woman was evaluated because of a progressive myelopathy with bowel and bladder dysfunction. She had had a subtotal resection of a conus medullaris teratoma when she was 20 years old. Emergency myelography showed a large intradural mass at L 1L2 causing an almost complete block. Delayed CT scanning confirmed an intradural mass of soft-tissue density causing abrupt attenuation of th...

Guillain-Barré syndrome is a relatively common, acute, and rapidly progressive, inflammatory demyelinating polyneuropathy. The diagnosis is usually established on the basis of symptoms and signs, aided by cerebrospinal fluid findings and electrophysiologic criteria. Previously, radiologic examinations have been used only to rule out other spinal abnormalities. We report a case of systemic lupus...

Primary malignant melanoma of the central nervous system is an extremely rare neoplasm and accounts for approximately 1% of all melanoma cases. The occurrence of this lesion in the spinal cord is even rarer.1-3 Magnetic resonance imaging features of melanoma are determinated by the degree of pigment melanin and the presence of acute or chronic hemorrhage and can be easily misdiagnosed with othe...

Posterior epidural migration of free disc fragments is rare, and posterior migration of the free fragments causing cauda equina syndrome is exceptionally rare. This report describes a 53-year-old man with disc fragment extrusion at the levels of L3-4 and a 54-year-old man with disc fragment extrusion at L5-S1 intervertebral space. The patients responded well to the operative therapy with comple...

A 7-year-old girl with primary varicella presented with encephalopathy and focal neurologic deficits 10 days after her first skin lesions appeared. She was discovered to have bilateral wedge-shaped renal infarctions, and ischemic lesions in the conus medullaris, cerebral cortex, and deep gray matter consistent with a medium and large vessel arteritis on magnetic resonance imaging. This complica...
