BACKGROUND: Primary intramedullary spinal glioblastoma multiforme (GBM) lesions are very rare comprising only 1.5% of all spinal cord tumors. These lesions typically result in rapid neurological deterioration and are associated with a very poor prognosis. CASE DESCRIPTION: A 16-year-old male exhibited a slowly progressive paraparesis with urinary incontinence, ultimately resulting in paraplegia. On magnetic resonance (MR), he was diagnosed with an intramedullary GBM of the spinal cord extending from the T9 level through the conus medullaris...

BACKGROUND: Spinal artery aneurysms (SAAs) are extremely rare lesions that can occur in isolation or associated with vascular malformations. Herein, we present three unusual cases of SAAs, and discuss imaging, diagnosis and surgical management strategies. CASE DESCRIPTION: The first case was a 57-year-old woman who presented with sudden onset of severe headache. Spinal angiography demonstrated an isolated anterior spinal artery (ASA) aneurysm at the level of craniocervical junction...

RATIONALE: Chiari type I malformation (CM1) and occult tethered cord syndrome (OTCS) are considered to be malformations associated with subtle structural abnormalities of the terminal filum. Few studies have reported patients with CM1 and OTCS. Treatment strategy for patients of CM1 associated with OTCS is controversial. PATIENT CONCERNS: A 14-year-old child was admitted with intermittent pain and numbness in the right upper limb. And he had urinary frequency, neck pain, back pain, and numbness simultaneously...

BACKGROUND: The presence of vertebral fractures affect variations in the termination level of conus medullaris (TLCM) and alter neurological findings. However, few studies have examined association between vertebral fractures, TLCM, and neurological findings. Thus, we herein studied the number and severity of vertebral fractures, TLCM, and neurological findings to clarify the mechanism of neurological deterioration in patients with vertebral fractures. METHODS: A total of 411 patients who underwent computed tomographic myelography were classified into those with (group F, n = 73) and those without vertebral fractures (group C, n = 338)...

Spinal DAVFs have diverse presentations. MRIs reveal spinal cord swelling in only 45-74%. We present an unusual case of a 57 yo male with a craniocervical junction DAVFs in which the edema appeared in the thoracolumbar region skipping the cervical spinal cord. A case report and literature review from a tertiary referral center. In our patient, symptoms progressed over 3 months from low back and radicular pain to weakness, saddle anesthesia, and urinary retention. MRI showed T2 hyperintensity from T3-4 to the conus medullaris (Fig 1 a,b)...

BACKGROUND AND IMPORTANCE: An adult patient was referred to our department for tethered cord syndrome. A lumbar magnetic resonance imaging showed a conus medullaris at the S2 level and the caudal part of the dural sac at the S3 level. We present a minimally invasive spine surgery procedure at the hiatus level for the treatment of tethered cord syndrome by the surgical section of the filum terminale externum, which avoids bone demolition. CLINICAL PRESENTATION: A 65-yr-old Caucasian man was referred for dysesthesia and a burning sensation in his lower limbs, which was both spontaneous and triggered by contact with his clothes...

INTRODUCTION: The arterial basket of the conus medullaris is one of several anastomoses between the anterior and posterior spinal arteries. The anatomy of this structure has attracted little attention. This work sought to investigate its configuration in human spinal cords. MATERIALS AND METHODS: Spinal cords from male and female cadavers (n=32) were injected with colored latex through the intercostal, lumbar, medial sacral and the posterior trunks of the hypogastric arteries...

BACKGROUND: The cranio-cervical junction is a rare location for spinal dural arteriovenous fistulas (dAVF). Typically, fistulas at this location present with findings related to intracranial cortical venous reflux or with cervical myelopathy. We present a case of cranio-cervical junction dAVF with isolated clinical and radiographic findings of thoracolumbar myelopathy. CASE DESCRIPTION: A 54 year-old male presented with subacute onset of lower extremity weakness, paresthesias and gait dysfunction...

A 1-year and 11-month- old English Cocker Spaniel was evaluated for clinical signs of progressive right pelvic limb lameness and urinary incontinence. Neurological examination was suggestive of a lesion localized to the L4-S3 spinal cord segments. No abnormalities were seen on magnetic resonance imaging (MRI) performed in the dog in dorsal recumbency and the hips in a neutral position and the conus medullaris ended halfway the vertebral body of L7. An MRI of the hips in extended and flexed positions demonstrated minimal displacement of the conus medullaris in the cranial and caudal directions, respectively...

INTRODUCTION: Syringomyelia is a disorder in which a cyst, or syrinx, develops within the spinal cord. Historically, syringomyelia in post-traumatic spinal cord injury has been uncommon; however, its diagnosis has been increasing due to the advances in medical technology. Syringomyelia that involves the entire spinal cord, or holocord, is rare after traumatic spinal cord injury, with only a few cases reported in the literature. CASE PRESENTATION: We present a case of a 57-year-old male who had a motorcycle accident 30 years ago resulting in a spinal cord injury, who presented a rapid decline in the function of his left upper extremity...

Traumatic thoracolumbar burst fractures are one of the most common forms of spinal trauma with the majority occurring at the junctional area where mechanical load is maximal (AOSpine Thoracolumbar Spine Injury Classification System Subtype A3 or A4). Burst fractures entail the involvement of the middle column, and therefore, they are typically associated with bone fragment in the spinal canal, which may cause compression of the spinal cord, conus medullaris, cauda equina, or a combination of these. Fortunately, approximately half of the patients with thoracolumbar burst fractures are neurologically intact due to the wide canal diameter...

INTRODUCTION: Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. METHODS: Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina...

Hemangiomas have rarely been found in the spinal cord. A few cases of spinal capillary hemangioma have been reported since 1987. The authors reported the two cases of capillary hemangioma including the tumor at conus medullaris and the another mimicked von Hippel-Lindau disease. A 15-year-old man was presented with coccydynia and left leg pain. A magnetic resonance imaging (MRI) revealed an intradural extramedullary enhancing mass at conus medullaris. Another case, a 31-year-old man was presented with a history of familial history of brain tumor, retinal hemangioma both eyes, multiple pancreatic cyst and syringobulbia with syringohydromyelia...

Purpose: The filum terminale (FT) is a fibrous band that connects the conus medullaris to the posterior body of the coccyx. Considering the advances of ultrasonography (US) technology and improvements in the resolution of US images, we aimed to re-establish the US features of the normal FT in infants younger than 6 months of age. Methods: We retrospectively reviewed 30 spinal US scans, stored as video clips. The internal structure of the FT and the marginal echogenicity of the FT were assessed, and transverse and longitudinal US were compared...

BACKGROUND: Spinal epidermoid cysts are benign tumors, which are rarely seen as an intradural extramedullary spinal cord tumor in the conus medullaris region. Acquired spinal epidermoid cysts are mostly caused by iatrogenic procedures, such as lumbar puncture, and the majority of acquired spinal epidermoid cysts have been reported below the L1 level, because lumbar puncture is usually performed around the iliac crest. Here, we report an extremely rare case of an epidermoid cyst that occurred as an intradural and extramedullary spinal cord tumor attached to the conus medullaris after repetitive epidural anesthesia...

INTRODUCTION: Since 14 years of age, the patient had experienced extreme penile pain within seconds of initial sexual arousal through masturbation. Penile pain was so severe that he rarely proceeded to orgasm or ejaculation. After 7 years of undergoing multiple unsuccessful treatments, he was concerned for his long-term mental health and for his future ability to have relationships. AIM: To describe a novel collaboration among specialists in sexual medicine, neurophysiology, and spine surgery that led to successful management...

OBJECTIVE Sacrococcygeal dimples in neonates and infants are of uncertain pathological import. Previously they were believed to be rarely associated with intraspinal anomalies. Recent studies using MRI, however, revealed that 6%-7% of pediatric cases of sacrococcygeal dimples were associated with anatomical tethered spinal cord (TSC). Because the prevalence of tethered cord syndrome is still unclear, there is no consensus among pediatric neurosurgeons on the management of children with sacrococcygeal dimples...

BACKGROUND: Spinal cavernous malformations usually affect the vertebral bodies and are seldom intradural. Here, we report a rare spinal intradural-extramedullary cavernous malformation associated with extensive superficial siderosis along the neuraxis in a patient with radicular complaints. CASE DESCRIPTION: A 60-year-old male presented with subacute headaches, intermittent fever, and acute back and radicular leg pain for 1-2 weeks. Magnetic resonance imaging revealed an intradural-extramedullary lesion just below the conus medullaris (at the L2 level)...
