1/29. Spinal arachnoiditis following subarachnoid haemorrhage: report of two cases and review of the literature.Two patients with spinal arachnoiditis following subarachnoid haemorrhage are described. A complete spinal block was seen at the mid thoracic level with characteristics of spinal arachnoiditis. Only one patient had severe symptoms. Both patients were treated conservatively. signs and symptoms diminished in time. A review of the literature is given and the aetiology is discussed.- - - - - - - - - - ranking = 1keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
2/29. Surgical management of syringomyelia associated with spinal adhesive arachnoiditis.The authors describe a new surgical technique to minimise the postoperative recurrence of adhesion after microlysis of adhesion to treat syringomyelia associated with spinal adhesive arachnoiditis. A 47 year old male presented with numbness of the lower extremities and urinary disturbance and was demonstrated to have a case of syringomyelia from C1 to T2 which was thought to be secondary to adhesive spinal arachnoiditis related to a history of tuberculous meningitis. Following meticulous microlysis of the adhesions, maximal expansion of a blocked subarachnoid space was performed by expansive duraplasty with a Gore-Tex surgical membrane, expansive laminoplasty and multiple tenting sutures of the Gore-Tex graft. Postoperatively, the syringomyelia had be en completely obliterated and improvement of the symptoms had been also achieved. The technique described may contribute to improvement of the surgical outcome following arachnoid dissection by maintaining continuity of the reconstructed subarachnoid space.- - - - - - - - - - ranking = 0.16687840195735keywords = subarachnoid (Clic here for more details about this article) |
3/29. Spinal toxoplasmic arachnoiditis associated with osteoid formation: a rare presentation of toxoplasmosis.STUDY DESIGN: An extremely rare presentation of an isolated spinal toxoplasmic arachnoiditis is described. OBJECTIVE: To draw attention to the fact that spinal arachnoid membranes may be a potential reservoir for toxoplasma gondii. SUMMARY OF BACKGROUND DATA: central nervous system toxoplasmosis is a common manifestation in patients who are immunodeficient. Reports on the spinal toxoplasmosis are rare and focused on spinal cord involvement. methods: An adult patient presented with symptoms of spastic paraparesis that had begun 13 years before admission. Thoracic spinal magnetic resonance imaging showed small lesions in posterior subarachnoid space at Th7-Th8. A Th7-Th8 laminectomy was performed. Intradural-extramedullary lesions were excised. RESULTS: Clinical, immunologic, and pathologic examinations showed adhesive spinal arachnoiditis associated with osteoid formation caused by past toxoplasmic infection. There was no impairment of the immunologic defense system. CONCLUSION: Where no causative factor is found in serious spinal adhesive arachnoiditis, the possibility of spinal toxoplasmosis should also be investigated.- - - - - - - - - - ranking = 0.083439200978674keywords = subarachnoid (Clic here for more details about this article) |
4/29. How frequent is chronic lumbar arachnoiditis following intrathecal Myodil?Chronic lumbar arachnoiditis has numerous causes, including the introduction of contrast media into the lumbar subarachnoid space. The oily contrast medium Myodil (iophendylate) is often cited but the true incidence of symptomatic lumbar arachnoiditis due solely to the presence of Myodil is unknown. A retrospective review of 98 patients in whom Myodil was introduced by ventriculography or cisternography, i.e. remote from the lumbar spine, revealed no cases of chronic lumbar arachnoiditis. All patients were monitored closely for periods ranging from 1 to 28 years. We conclude that, in these circumstances, it is rare for Myodil to produce symptomatic arachnoiditis.- - - - - - - - - - ranking = 0.083439200978674keywords = subarachnoid (Clic here for more details about this article) |
5/29. Acute spinal epidural abscess and spinal leptomeningitis: report of 2 cases with comparative neuroradiological and autopsy study.A 21-year-old male developed back pain, fever, and rapidly progressive quadriparesis. Lumbar tap yielded frank pus which was confirmed on magnetic resonance imaging (MRI) to be located mainly in the cervical epidural space. Conservative antibiotic remedy was partially effective for restoration of the neurological deficits. A 82-year-old female noticed low-back pain which was rapidly accompanied with clouding of consciousness, paraplegia, and sphincter disturbances. Lumbar puncture revealed thick pus which was best depicted on MRI in the thoracolumbar subarachnoid space. At autopsy, spinal subarachnoid abscess or leptomeningitis was confirmed, and a spinal infarction previously unrecognized on MRI was found. Usefulness and shortcomings of MRI in the diagnosis of paraspinal infections are discussed.- - - - - - - - - - ranking = 0.16687840195735keywords = subarachnoid (Clic here for more details about this article) |
6/29. MRI of spinal intradural arachnoid cyst formation following tuberculous meningitis.Secondary intradural arachnoid cyst involving the spine is uncommon. It is usually secondary to trauma, haemorrhage, surgery or inflammation. We present two cases of treated tuberculous meningitis, which presented with gradual onset of quadriplegia and paraplegia, respectively. MRI revealed intradural (cervical and thoracic) arachnoid cysts (ventral and dorsal to the spinal cord) with myelomalacic cord changes. Ventral location of such spinal arachnoid cysts, and being secondary to tuberculous arachnoiditis are distinctively uncommon features. The rarity of this condition and the relevance of MRI in the accurate diagnosis have been discussed here.- - - - - - - - - - ranking = 0.0010433216056239keywords = haemorrhage (Clic here for more details about this article) |
7/29. Steroid responsive late deterioration in cryptococcus neoformans variety gattii meningitis.The authors describe the clinical course of cryptococcus neoformans variety gattii infection in a young immunocompetent man who had a late deterioration characterized by headaches, subarachnoid inflammation, hydrocephalus, and stroke that reproducibly responded to steroids. These findings, in combination with declining markers of CSF infection, are consistent with the late deterioration being caused by sterile arachnoiditis rather than ongoing infection.- - - - - - - - - - ranking = 0.083439200978674keywords = subarachnoid (Clic here for more details about this article) |
8/29. Subarachnoid pressure-dependent change in syrinx size in a patient with syringomyelia associated with adhesive arachnoiditis. Case report.The pathophysiology of syringomyelia is still not well understood. Current prevailing theories involve the assumption that cerebrospinal fluid (CSF) flows into the syrinx from the subarachnoid space through the perivascular space of Virchow-Robin. Reported here is the case of a patient with syringomyelia in which this course is clearly contradicted. This patient with a holocord syrinx associated with adhesive arachnoiditis was treated 3 years previously with insertion of a subarachnoid-peritoneal shunt and had recently experienced worsening myelopathy. On surgical exploration, the shunt system was functioning normally. The medium-pressure shunt valve was replaced with an adjustable valve with a higher closing pressure setting, thus increasing the CSF pressure in the subarachnoid space. Contrary to prevailing theories, this procedure markedly reduced the size of the syrinx. This case provides direct evidence that the syrinx size is inversely related to subarachnoid CSF pressure and supports the hypothesis that the pressure gradient across the spinal cord parenchyma is the force that generates syringes in syringomyelia.- - - - - - - - - - ranking = 0.3337568039147keywords = subarachnoid (Clic here for more details about this article) |
9/29. Arachnoid cyst with associated arachnoiditis developing after subarachnoid hemorrhage. Case report.The authors report the case of a 53-year-old woman in whom a T1-T2 spinal arachnoid cyst with associated arachnoiditis developed, compressing the thoracic spinal cord 1 year after the patient had suffered a Hunt and Hess Grade IV subarachnoid hemorrhage (SAH). Development of spinal arachnoiditis with or without an arachnoid cyst is a rare complication of aneurysmal SAH. risk factors may include posterior circulation aneurysms, the extent and severity of the hemorrhage, and the need for cerebrospinal fluid diversion. Surgical drainage, shunt placement, or cyst excision, when possible, is the mainstay of treatment.- - - - - - - - - - ranking = 0.41719600489337keywords = subarachnoid (Clic here for more details about this article) |
10/29. Unusual complications of the treatment of chronic spinal arachnoiditis.The causes, diagnostic features, and therapy of chronic spinal arachnoiditis are reviewed. Two unexpected results from attempted epidural injections (one of lignocaine and clonidine, and one of lignocaine, clonidine, and morphine) in patients with this condition are described. The anatomical abnormalities of the epidural and subarachnoid spaces in such patients and the consequent unpredictable and potentially dangerous results that may follow drug injection into these spaces are discussed.- - - - - - - - - - ranking = 0.083439200978674keywords = subarachnoid (Clic here for more details about this article) |
