1/5. L4-5 disk lesion resulting in back pain with bowel, bladder and sexual dysfunction without paraparesis.This is a case report of a patient with bowel, bladder and sexual dysfunction associated with low back pain. This patient had an essentially normal neurological examination. There was radiological evidence of a disk lesion, and urodynamic findings consistent with lower motor neuron bladder dysfunction. His symptoms are attributed to a L4-5 disk herniation resulting in a partial cauda equina syndrome. The relevant anatomy is reviewed, and the differential diagnosis is discussed.- - - - - - - - - - ranking = 1keywords = cauda equina syndrome, equina syndrome, cauda equina, equina, cauda (Clic here for more details about this article) |
2/5. cauda equina syndrome after spinal anaesthesia with hyperbaric 5% lignocaine: a review of six cases of cauda equina syndrome reported to the Swedish Pharmaceutical insurance 1993-1997.Six cases of cauda equina syndrome with varying severity were reported to the Swedish Pharmaceutical insurance during the period 1993-1997. All were associated with spinal anaesthesia using hyperbaric 5% lignocaine. Five cases had single-shot spinal anaesthesia and one had a repeat spinal anaesthetic due to inadequate block. The dose of hyperbaric 5% lignocaine administered ranged from 60 to 120 mg. Three of the cases were most likely caused by direct neurotoxicity of hyperbaric 5% lignocaine. In the other 3 cases, direct neurotoxicity was also probable, but unfortunately radiological investigations were not done to definitely exclude a compressive aetiology. All cases sustained permanent neurological deficits. We recommend that hyperbaric lignocaine should be administered in concentrations not greater than 2% and at a total dose preferably not exceeding 60 mg.- - - - - - - - - - ranking = 6.2862999618708keywords = cauda equina syndrome, equina syndrome, cauda equina, equina, cauda (Clic here for more details about this article) |
3/5. Congenital vesicovaginal fistula.Congenital vesicovaginal fistula is a very rare entity, the etiology of which has not been clearly elucidated because pathologic features have not been mentioned in previous reports. The case of a 4-year-old girl having incontinence resulting from a congenital vesicovaginal fistula joining with the left ectopic ureter from the hypoplastic kidney is described. This is thought to be the first presentation of congenital vesicovaginal fistula joining with ectopic ureter. A microscopic examination revealed the fistula consisting of transitional cell epithelium, suggesting an abnormal fusion of the ureteral bud and caudal end of the mullerian duct with the urogenital sinus.- - - - - - - - - - ranking = 0.012245765899647keywords = cauda (Clic here for more details about this article) |
4/5. Radiographic, computed tomographic and histopathologic appearance of a presumed spinal chordoma in a dog.A 4-year-old Labrador Retriever presented for urinary incontinence and constipation of 2 weeks duration. There was a tender abdomen, lumbar pain and conscious proprioceptive deficits in both pelvic limbs. Depressed pelvic limb reflexes were present consistent with a lower motor neuron lesion. In radiographs of the lumbar spine there was narrowing of the intervertebral disc space at L5-L6 with irregular, multifocal areas of mineralized opacities dorsal to the intervertebral disc space, presumably within the vertebral canal. On computed tomography, an intramedullary, partially mineralized mass was identified in the spinal cord at the level of caudal L5 through cranial L6. At necropsy there was a four-centimeter enlarged, irregular segment of spinal cord at the level of L5-L6. When sectioned, the spinal cord bad a mineralized texture. Histologically there were variable sized cells that were stellate in appearance with vacuolated cytoplasm (physaliferous cells) and mucinous background consistent with a chordoma. chordoma is a rare, skeletal neoplasm that originates from mesoderm-derived notochord and has been reported in humans and animals. Extraskeletal development of a chordoma within the spinal cord is a rare manifestation of this neoplasm. However, based on other reports in dogs, solitary extraskeletal locations of chordomas may be the typical expression of this neoplasm in the dog. Differentiation of similar histologically appearing tumors, such as a parachordoma or myxoid chondrosarcoma, will require immunohistochemical characterization of these tumors in veterinary patients.- - - - - - - - - - ranking = 0.012245765899647keywords = cauda (Clic here for more details about this article) |
5/5. Untethered filum terminale presenting as cauda equina lesion.We report the case of a young girl with recurrent bladder dysfunction. magnetic resonance imaging performed for evaluation of initial urologic symptoms revealed a low-lying conus medullaris. She underwent an L5 laminectomy and cord untethering by sectioning of the filum terminale. After initial improvement of bladder function, her symptoms returned 4 years later. Repeat magnetic resonance imaging demonstrated a new intradural lesion at L2. At surgery she was found to have an untethered, thickened, coiled filum terminale at L2.- - - - - - - - - - ranking = 0.39505760509068keywords = cauda equina, equina, cauda (Clic here for more details about this article) |
