摘要: Introduction Intradural spinal arachnoid cysts (SACs) are among many etiologies for syringomyelia. Consequentially, neurologic symptoms arise such as pain, gait disturbance, and bladder dysfunction. Identification of SAC on magnetic resonance imaging (MRI) can be challenging, SACs fenestrated or in the form fine webs. Methods Imaging clinical data 7 patients who underwent surgical treatment associated with syringomyelia were reviewed. All previous publications this pathology reviewed via MEDLINE search. Results Seven a mean age 59 years found to have causing Intraoperative exploration confirmed appearances webs fluid-filled loculation impinging cord. Common presentations back incontinence. Diagnosis was made by MRI, although 3 cases, not identified initial review. Computed tomography myelogram performed one case due enlarged lack obvious cord compression. Thoracic laminectomy/laminoplasty all patients, centered at level subtle indentation cord; proper directly addressed. Postoperatively, had complete resolution their MRI demonstrating Conclusions Careful evaluation demonstrate caudal cephalad end may obviate need additional imaging. Meticulous dissection establishment good CSF flow is sufficient syringomyelia, averting more aggressive procedures.
