1/6. arachnoiditis ossificans and syringomyelia: a unique case report.A 62-year-old male presented with progressive quadriparesis. magnetic resonance imaging of the spine revealed a spinal cord syrinx but failed to detect extensive arachnoiditis ossificans noted on insertion of a syringopleural shunt. A postoperative computed tomography scan clearly demonstrated the abnormality and its extent. We present a rare case of syringomyelia resulting from spinal arachnoiditis ossificans and review the relevant literature.- - - - - - - - - - ranking = 1keywords = arachnoiditis (Clic here for more details about this article) |
2/6. 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 = 3.5keywords = arachnoiditis (Clic here for more details about this article) |
3/6. arachnoiditis ossificans of the cauda equina. Case report and review of the literature.The authors describe a case of arachnoiditis ossificans (AO) of the cauda equina. The lesion is a rare pathological entity usually confined to the thoracic and high lumbar regions that can cause progressive spinal cord and cauda equina compression, inducing severe neurological deterioration. The authors analyze the clinical symptoms, radiological features, histological data, and treatment options relating to this case and 13 others described in the literature; additionally, they consider the possible mechanisms responsible for ossification of the leptomeninges. Although clustered arachnoidal cells are usually implicated in its pathogenesis, an environment induced by arachnoiditis and disturbed cerebrospinal fluid flow appears to be a more important factor. A therapeutic strategy is proposed for AO for which no effective treatment currently exists.- - - - - - - - - - ranking = 1keywords = arachnoiditis (Clic here for more details about this article) |
4/6. Spinal arachnoiditis ossificans: report of three cases.OBJECTIVE AND IMPORTANCE: Although the clinical and histological features of the pathological entity of spinal arachnoiditis ossificans (AO) have been established for some time, less attention has been paid to the treatment. We propose a classification of spinal AO evaluating the possibilities and indications for surgical or conservative treatment.CLINICAL PRESENTATION: Type III has a lumbar localization, presents with less neurological involvement, and usually requires conservative treatment. In Types I and II, which are usually thoracic, clinical worsening justifies surgical decompression or partial removal, whereas total removal is rarely achievable.INTERVENTION: The literature was reviewed, and the reports on three patients were added to the published cases. On the basis of a reappraisal of the computed tomographic and magnetic resonance imaging documentation and the surgical descriptions, the cases of AO were classified into three types: semicircular (Type I), circular (Type II), and englobing the caudal fibers (Type III). The indications for treatment were evaluated in terms of surgical possibilities and outcome.CONCLUSION: The classification proposed on the basis of radiological findings allows sufficient clinical differentiation of AO and evaluation of the possibilities for surgical treatment. The latter is conditioned by the type of arachnoiditis, degree of neurological involvement, and presence of any concomitant pathological findings.- - - - - - - - - - ranking = 3keywords = arachnoiditis (Clic here for more details about this article) |
5/6. Spinal ossifying arachnoiditis. Case report.A case of low dorsal spinal cord compression, due to ossifying arachnoiditis, is reported. Its relationship with a venous malformation overlying the dorsal surface of the spinal cord is mentioned. The literature is reviewed and possible etiopathogenetic factors favouring this rare condition are discussed in the light of few similar reports. The value of surgical treatment is stressed.- - - - - - - - - - ranking = 2.5keywords = arachnoiditis (Clic here for more details about this article) |
6/6. Case report: computed tomography findings in spinal arachnoiditis ossificans.Spinal arachnoiditis ossificans is rarely diagnosed radiologically.
