Intradural extramedullary spinal infections causing cauda equina compression are uncommon. We report an Escherichia coli bacteraemia causing lumbar discitis and an intracanalicular collection compressing the cauda equina: initially thought to be an epidural empyema, however microsurgery revealed an intradural location. Decompression, drainage, antibiotics, and neuropathy treatment are essential management.

Suspected cauda equina syndrome (CES) requires urgent evaluation, investigation and treatment. Timing of cauda equina decompression is crucial, and delays in its management, leading to significant irreversible disability can be devastating for patient and surgeon alike. The standard of care in CES therefore needs to be clear and unambiguous. Todd and Dickson have written an excellent paper summarising the condition, and have outlined what they feel is the standard of care. We would ask the authors to clarify an important point...

INTRODUCTION: Patients with cauda equina syndrome (CES) are frequently referred late when neurological damage cannot be reversed. National Guidelines for emergency referral, imaging and treatment of CES contain symptoms and/or signs that are those of late often, irreversible CES. Referral at this stage may be too late for that patient. METHODS: Seven sources were reviewed. Advice re emergency referral/imaging/treatment were reviewed. Symptoms/signs were compared with a standard classification of CES...

Myxopapillary ependymoma (MPE) is a rare variant of ependymoma that is most commonly located in the cauda equina and filum terminale. We present a case of 23-year-old man diagnosed with MPE in the fourth ventricle and sacral canal area with extensive disseminated lesions along the cerebrospinal ventricular system. Additionally, a molecular pathological diagnosis was performed. The patient underwent a craniotomy and a lumbar laminectomy. In the course of 18 months of follow-up, the patient have recovered very well...

A 63-year-old man presented with right-sided hemianopia and unsteady gait. Brain MRI revealed multiple hyperintense infarct-like lesions on diffusion-weighted images (DWI). Hyperintensity persisted in some of these lesions even after 6 weeks, although his symptoms were ameliorated then. The patient developed episodic dizziness and a transient event of apraxia at 18 weeks after the first episode. Brain MRI revealed additional hyperintense lesions on DWI, which persisted even after 7 weeks. Eventually, the patient manifested cauda equina syndrome 39 weeks after the first episode...

An approach using a complete cranial iliac osteotomy (CCIO) to access the lumbosacral (LS) foramen in dogs from lateral was developed using cadavers and applied in a clinical patient with degenerative lumbosacral stenosis (DLSS). The foraminal enlargement in the cadavers and the patient was documented on postoperative CT scans. The preoperative CT scan of the patient showed moderate cranial telescoping of the sacral roof and a moderate central disk protrusion, leading to moderate to severe compression of the cauda equina...

INTRODUCTION: Paragangliomas of filum terminale are rare benign tumors, arising from the adrenal medulla or extra-adrenal paraganglia. These lesions usually present with chronic back pain and radiculopathy and only two cases of acute neurological deficit have been reported in literature. PRESENTATION OF CASE: A case with an acute paraplegia and cauda equina syndrome due to an hemorrhagic paraganglioma of the filum terminale is described. Magnetic resonance imaging showed an intradural tumor extending from L1 to L2 compressing the cauda equina, with an intralesional and intradural bleed...

Bardet-Biedl syndrome (BBS) is a rare, autosomal-recessive, debilitating genetic disorder, which can present with multitudinous systemic clinical features including rod-cone dystrophy, polydactyly, Frohlich-like central obesity, mental retardation, hypogonadism, and renal anomalies. Diverse neuromuscular manifestations in patients afflicted by this heterogeneous disorder include ataxia, cervical, and thoracic canal stenoses, presenting as spastic quadriparesis and other gait disturbances. We report a young patient with BBS, who had presented with acute flaccid paraparesis due to severe primary lumbar canal stenosis...

Hydatidosis, caused by Echinococcus granulosus, affects the spinal column in 0.5-2% of all cases, with the sacral column being a rare location typically observed only in adults. The case is reported of a 14-year-old boy from Juliaca (Puno, Peru) who presented with chronic lower back pain and cauda equina syndrome. He was initially attended to in Juliaca, and then transferred to the Hospital Edgardo Rebagliati Martins (Lima, Peru) with a diagnosis of sacral tumor. In magnetic resonance imaging, a multicystic tumor was seen with L5 and S1 lysis and instability...

The evaluation of the electrically induced bulbocavernosus reflex (BCR) using electromyography (EMG) is a useful tool for evaluating the integrity of sacral spinal segments 2 to 4, and that of their afferent and efferent connections in the urogenital region. In the current retrospective study, the value of this technique in predicting the outcome of bladder dysfunction was investigated in patients with cauda equina syndrome (CES). Electrically induced BCR (E-BCR) was evaluated in 40 patients with bladder dysfunction due to CES at the subacute stage (7-90 days)...

STUDY DESIGN: A systematic review. OBJECTIVES: Conus medullaris syndrome (CMS) and cauda equina syndrome (CES) are well-known neurological entities. It is assumed that these syndromes are different regarding neurological and functional prognosis. However, literature concerning spinal trauma is ambiguous about the exact definition of the syndromes. METHODS: A MEDLINE, EMBASE and Cochrane literature search was performed. We included original articles in which clinical descriptions of CMS and/or CES were mentioned in patients following trauma to the thoracolumbar spine...

OBJECTIVE: Elsberg syndrome (ES) is an established but often unrecognized cause of acute lumbosacral radiculitis with myelitis related to recent herpes virus infection. We defined ES, determined its frequency in patients with cauda equina syndrome (CES) with myelitis, and evaluated its clinical, radiologic, and microbiologic features and outcomes. METHODS: We searched the Mayo Clinic medical records for ES and subsequently for combinations of index terms to identify patients with suspected CES and myelitis...

Intradural spinal arachnoid cysts (ISACs) have been reported in the current literature as either an idiopathic disease or exceedingly rare sequelae after lumbar puncture, spinal trauma, or meningitis. Other studies have more appropriately termed the iatrogenic pathology as a spinal subdural extra-arachnoid hygroma (SSEH), as there is not often a clear cyst wall as in a true arachnoid cyst. However, to the best of our knowledge, none of the previous studies described an SSEH following uncomplicated posterior lumbar surgery, as they have previously involved clear durotomies during the initial operation...

PURPOSE: Arteriovenous fistula (AVF) of the cauda equina (CE) fed by the proximal radicular artery (PRA) is very rare, and the differentiation from that of the filum terminale (FT) is important to avoid treatment-related injury to the CE when endovascular treatment is selected. The authors describe a case of AVF of the CE fed by the PRA, demonstrate the anatomical features and discuss the treatment precautions. METHODS: A 69-year-old man presented with a transient weakness of lower limbs...

Spinal nerve sheath tumors are well known to typically originate from dorsal sensory nerve roots. However, it is difficult to anatomically identify the origin in the case of cauda equina tumors. In this study, we aimed to ascertain whether a cauda equina nerve root removed with a nerve sheath tumor was a motor nerve using acetylcholinesterase (AchE) staining. Nerve rootlet sections removed with tumors were stained for AchE using the AchE Rapid Staining Kit. Additionally, we performed intraoperative motor-evoked potential (MEP) monitoring following either transcranial electrical stimulation (TES) or electrical stimulation of nerve rootlets...

Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system but isolated primary spinal NCC is of very rare occurrence. The authors report a case of 44-year-old male, a postoperative case of multiple spinal NCC lesion excision 2 years ago, who presented with cauda equina syndrome and magnetic resonance imaging revealed a lesion mimicking an arachnoid cyst in the D1-9 region of the spinal cord. On intraoperative surgical exposure multiple cysts were found and excised. The suspicion of recurrence of NCC was confirmed by histopathology...
