A 62-year-old man with acute paraplegia was transferred to our hospital. He had flaccid paraplegia and multiple cranial nerve palsies, such as mydriasis of the left pupil, abduction palsy of the left eye, hoarseness and dysphagia, but no meningeal irritation signs. MRI of the spinal canal showed swellings of the conus medullaris and the cauda equine, and also contrast enhancement of the spinal meninges. The cerebrospinal fluid (CSF) showed pleocytosis and protein increment. The lymph node was swollen in his right axilla...

The increasing migration of people from their homeland in far distant regions to Europe in the last few years has strongly influenced the rise of previously rarely seen diseases. They not only originate from the respective homeland but also from the transit countries during the migration process. We report the case of a 27-year-old male migrant from Eritrea, who after months of flight as a refugee travelling through various African countries, presented at our hospital with a progressive, painful radiculopathy...

OBJECTIVE: The purpose of the report is to describe a patient with hereditary osteochondromatosis and spinal cord compression at the thoracic level. CLINICAL FEATURES: An 8-year-old patient with hereditary osteochondromatosis inherited from his father presented paraparesis in the left foot, leading to complete paralysis in both legs. INTERVENTION: In a CT scan, a bony tumor rising from the posterior wall of the T3 body narrowing the spinal canal, and the MRI spinal cord compression at the same level and the hydrosyringomyelic cavity extended to the conus medullaris; with an anterior thoracic approach to T2-T4, the fibro-cartilaginous tumor was removed, and the stabilization was completed with bone graft and a plate...

Myxopapillary ependymoma (MPE) is a histological variant of ependymoma found in the conus medullaris or filum terminale region. Intracranial occurrence of the tumor is a rarity. The most characteristic histological feature of myxopapillary tumors is the abundance of intercellular and perivascular mucin and the arborizing vasculature, which tends to form papillae. We are reporting a 14-year-old patient presented with seizures caused by the right occipital region intraparenchymal lesion. Histopathology confirmed it to be MPE...

Spinal neurenteric cysts are very rare congenital anomalies and are commonly associated with other spinal malformations. They are usually located in intradural, extramedullary location. We report a rare case of intramedullary conus medullaris neurenteric cyst without any associated spinal malformation diagnosed preoperatively by magnetic resonance imaging.

BACKGROUND: A retained medullary cord (RMC) is a rare closed spinal dysraphism with a robust elongated neural structure continuous from the conus and extending to the dural cul-de-sac. One case extending down to the base of a subcutaneous meningocele at the sacral level has been reported. CLINICAL PRESENTATION: We report on three cases of closed spinal dysraphism, in which a spinal cord-like tethering structure extended out from the dural cul-de-sac and terminated at a skin-covered meningocele sac in the sacrococcygeal region, which was well delineated in curvilinear coronal reconstructed images of 3D-heavily T2-weighted images (3D-hT2WI)...

BACKGROUND: There is some evidence that anaesthetists often perform neuraxial blocks at a higher lumbar interspace than intended. It may be questioned whether parturients are at greater risk for neurological damage when the dura is perforated at a more cephalad interspace than L2-L3. METHODS: Thirty-six patients scheduled for elective Caesarean delivery under CSE anaesthesia were selected for study. Using a B-D Durasafe Adjustable needle combination, the skin-to-epidural distance and the width of the epidural space were measured and matched with 36 female patients undergoing the same anaesthetic technique for orthopaedic procedures...

OBJECTIVE Tethered cord syndrome (TCS) is a neurosurgical disorder with varied clinical manifestations believed to result from vascular compromise due to stretch forces on the spinal cord. Conventional supine MRI findings may include a low-lying conus medullaris, thickened or fat-infiltrated filum terminale, or lipoma; however, imaging sensitivity and specificity for tethered cord can be low. The purpose of this study was to evaluate the utility of prone MRI in the diagnosis of tethered and retethered spinal cord...

Solitary juvenile xanthogranuloma (SJX) of the spine is an extremely rare proliferative histiocytic disorder with only few cases reported in literature. We present the first case of intramedullary spinal SJX. A 22-year-old male presented with a nine-month history of progressively worsening sphincteric disturbances and saddle hypoesthesia. Magnetic resonance imaging showed an intra-axial lesion located in the conus medullaris; T1 hypointense, T2 iso-hyperintense and uniformly enhancing after contrast administration...

Oligodendrogliomas (OGD) are glial tumors, together with mixed oligoastrocytoma constituting 5-20% of all gliomas, which occur predominantly in younger populations and are managed with surgery and chemotherapy with good long-term prognosis after treatment and additionally present with low rates of metastases. We present the case of a 46-year-old patient with intracranial right frontal subcortical OGD [World Health Organisation (WHO) grade II] managed at the Neurosurgery Department in Foscal Clinic, Floridablanca, Colombia...

In this report, we present a case of an adult patient with a mature teratoma of the conus medullaris. The patient was a 29-year-old postpartum female patient who developed unexplained urinary retention. Lumbar spine magnetic resonance imaging (MRI) examination revealed an intradural partly enhancing mixed cystic and solid lesion with intralesional intrinsic T1 hyperintense components that were suppressed on fat suppressed sequences, inseparable from the conus medullaris. Surgical resection was performed and histopathology findings were consistent with a mature teratoma...

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)...

OBJECTIVES: Spinal dural arteriovenous fistulas (DAVFs) have diverse presentations. Magnetic resonance imaging (MRI) reveals spinal cord swelling in only 45% to 74% of cases. We present an unusual case of a 57-year old man with a craniocervical junction DAVF in which the edema appeared in the thoracolumbar region, skipping the cervical spinal cord. METHODS: A case report and literature review from a tertiary referral center are provided. RESULTS: In our patient, symptoms progressed over 3 months from low back and radicular pain to weakness, saddle anesthesia, and urinary retention...

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...
