BACKGROUND: A few cohort studies have determined which patients with lumbar spinal stenosis are likely to need surgery because of the deterioration of symptoms. However, there are still insufficient data regarding the management of lumbar spinal stenosis due to lack of prognostic factors associated with the need for surgery. The purpose of this study was to identify the prognostic factors associated with the need for surgical treatment in patients with lumbar spinal stenosis. METHODS: Patients with lumbar spinal stenosis from our hospital and related facilities were enrolled...

Spontaneous acute subarachnoid hemorrhage (SAH) from lumbar ependymoma in children is rare. We report a case of a14-year-old boy who developed sudden radicular low back pain while playing baseball. He was initially managed conservatively in a local hospital for suspected lumbar disc herniation, but later developed meningeal symptoms and fever before being referred to our hospital. There he underwent a diagnostic lumbar puncture in the emergency room; his cerebrospinal fluid suggested an SAH. Physical examination showed meningeal signs and cauda equina features...

INTRODUCTION: Neurological complications due to spinal anesthesia are dysesthesia, paresthesia, cauda equina syndrome, and neuropathic joint. However, neurological complications are rare. We report a case of neuropathic joint of knee as a complication of syrinx following postspinal anesthesia. CASE REPORT: A 33-year-old female came with complaints of pain and instability of her left knee and left foot drop. She had developed weakness of her left lower limb following her cesarean section surgery done under spinal anesthesia...

Extrusion of disc material within the spinal canal complicates up to 28.6% of lumbar disc herniations. Due to the anatomical "corridors" created by the anterior midline septum and lateral membranes, relocation occurs with an anterior and anterolateral axial topography. Posterior migration is an extremely rare condition and anterior-to-posterior circumferential migration is an even rarer condition. Its radiological feature can be enigmatic and since, in more than 50% of cases, clinical onset is a hyperacute cauda equina syndrome, it may imply a difficult surgical decision in emergency settings...

BACKGROUND: The blood brain barrier (BBB) is an impediment to the development of large and highly charged molecules as therapeutics for diseases and injuries of the central nervous system (CNS). Antisense oligonucleotides (ASOs) are large (6000-8000MW) and highly charged and therefore do not cross the BBB. A method of circumventing the blood brain barrier to test ASOs, and other non-BBB penetrant molecules, as CNS therapeutics is the direct administration of these molecules to the CNS tissue or cerebral spinal fluid...

BACKGROUND: Even though micturition, defecation, and sexual function are substantially affected in cauda equina syndrome (CES), data on outcome are scarce. METHODS: Medical files of patients operated on lumbar herniated disc were screened for CES and retrospectively analyzed for baseline characteristics, outcome of micturition, defecation, and sexual function and possible predictors. RESULTS: Seventy-five CES patients (52% men) were included with a mean age of 44 years...

Lumbar disc disease occurs mainly in the adult population. A disc prolapse in the paediatric population is very rare. Cauda equine syndrome resulting from compression of the cauda equina is a rare syndrome and is one of the few spinal surgical emergencies. Here we present a 13-year-old boy with pain in the lumbar region radiating bilaterally to the lower limbs, with asymmetrical weakness of lower the limbs, perianal hypoaesthesia and urinary retention. MRI of lumbar spine confirmed disc protrusion at the L3-L4 level with severe spinal canal stenosis...

BACKGROUND: Cauda equina syndrome is a rare disorder that causes loss of Lumbar plexus function (nerve roots) lower than conus medullaris. No risk factor has been defined for this disease yet. Due to the high morbidity of Cauda equina syndrome and lack of sufficient information about the connection between the disease and urodynamic findings and EMG (Electromyography) findings, the need for this comprehensive study is felt. OBJECTIVE: The aim is to determine the predictive power of findings resulted from urodynamics and electromyography of perineal region and around sphincter in the clinical cure rate of urination in patients with urinary retention followed by Cauda equina syndrome...

This is the case report of a contained ruptured aortic aneurysm presenting with acute cauda equina syndrome. The patient was a 79-year-old man. A literature search revealed various unusual presentations of abdominal aortic aneurysm (AAA), including femoral neuropathy, hip pain and others; however, there are no other reports of cauda equina-like syndrome. The present case is therefore another unusual presentation of ruptured abdominal aortic aneurysm and reiterates the utmost importance of careful history taking and clinical examination...

BACKGROUND AND PURPOSE: Chronic cauda equina syndrome, defined as persistent damage of the cauda equina nerve roots within the spinal canal can be a challenging diagnosis with varied presentations. MR neurography imaging is more commonly being used to evaluate the lumbosacral spine of patients suspected of having subacute or chronic cauda equina syndrome. Our aim was to evaluate the impact of lumbosacral plexus MR neurography in the diagnostic thinking and therapeutic management of patients presenting with chronic pelvic pain and dysfunction and suspected chronic cauda equina syndrome...

We present our recent experience with fluorescein sodium videoangiography (FLVA) in the intra-operative evaluation of a patient with conus medullaris arteriovenous malformation (AVM). To our knowledge this is the first report in the literature of use of FLVA in the surgery of spinal AVM. Intra-operative FLVA was done to identify an early filling vessel and to obliterate the site of fistulous connection. This was correlated and confirmed with simultaneous indocyanine green videoangiography (ICGVA). The conus and cauda equina roots could be appreciated and manipulated in relation to this fluorescence...

PURPOSE: Recurrent chordomas are difficult to control locally. This dosimetric study investigates the feasibility of dose escalation to hypoxic regions, visualized on FMISO-PET, while respecting the dose constraints to the neighboring normal tissues/organs. We propose to deliver a higher dose to the areas of hypoxia (84.5Gy) using IMPT with the goal of improving local control. METHODS: We currently have four patients with hypoxic subvolumes (HSV) greater than 10cc from the FMISO-PET image...
