Giant anterior arachnoid cyst associated with syringomyelia: implications for treatment and follow-up.

摘要: Study design A case report of a unique anterior intradural spinal arachnoid cyst (ISAC) associated with syringomyelia. Objective To discuss the surgical treatment and follow-up ISACs Summary background data Fenestration is commonly performed in cysts large craniocaudal extension Particularly, excision dorsal cysts, without shunting operation for syrinx, achieves excellent results. However, are different from having greater showing intracystic fibrous septae. Methods 55-year-old man presented small syringomyelic cavity at C1/C2 level giant extramedullary cystic spreading C1 to T11. posterior laminectomy C3 was performed, generous fenestration followed by positioning cyst-subarachnoid shunt. Results After surgery, transitory relief soon progressive worsening symptoms. specific kinematic-magnetic resonance imaging (K-MRI) then carried out, regular sisto-diastolic modulation flow normal shunt function. define real fluid dynamics within cyst, patient underwent computed tomography-myelography (CT-M). Only quantity contrast found inside pouch, confirming clinical diagnosis poor communication failure previous surgery. Conclusion This most extensive ISAC syringomyelia reported literature until now. The especially those located ventral spine syringomyelia, still matter debate. In our case, insertion alone were not sufficient restore CSF dynamics. addition, we show that K-MRI may be proper method postoperative these lesions.
