| Popis: | Background Intramedullary arachnoid cysts are rare cystic masses that are usually mixed with syringomiyelia. It is not necessarily a complication of any pathologic condition in the spine and/or brain but the etiology and management of this entity remains unclear. Syringomyelia is a disorder that is related to an abnormality of the brain and in most cases, occurs as a complication of other pathologies. The aim of this study is to establish the clinical and radiological characteristics of this intramedullary arachnoid cyst and discuss the differences between intramedullary arachnoid cyst and the syringomiyelias. Material and Method A total of 77 patients with intramedullary cystic masses were retrospectively assessed between 2002 and 2012 and 12 of them with intramedullary arachnoid cyst were analyzed statistically. All patients had initial scans and followed up with clinical examinations and MR images and neuro-electrophysiological tests. Results The average follow-up duration was 50 months (range 18-120 months). Mean axial intramedullary arachnoid cyst size was 13,26 ± 4.76 mm and a mean sagittal size was 23.29 ± 7.95 mm. Neurological examinations were normal in all except one patient who had minor sensory loss due to recent cervical trauma. There were no motor neurological deficits, and all patients remained asymptomatic or stable. Intramedullary arachnoid cyst size and shape remained unchanged radiologically, MEP and SSEP studies revealed normal median and tibial responses initially and at the end of the follow up in all patients. Conclusion It is probable that intramedullary arachnoid cyst has different radiologic findings and clinical signs/symptoms from syringomiyelia that are associated with different primary causes. And also, the treatment and following modalities are different in intramedullary arachnoid cyst. |
