Abstract:
Objective To explore the classification of intracranial arachroid cysts(IAC) in CT cisternography(CTC) and its clinicalapplication.Methods 22 cases of IAC diagnosed by plain CT underwent CTC exminaton. IACs were classified into noncommnicatingintracranial arachnoid cyst (NCIAC) and commnicating intracranial arachnoid cyst (CIAC) by wheather or not filled with contrast media in cysts on CTC. NCIAC cases were selected and treated with neuroendoscopic fenestration.Results 15 cases of NCIAC were found by CTC examination. All the NCIAC patients had definite neurologic findings. Postoperatively, all the patients were improved or cured. Follow-upplain CT scan of 9 NCIAC cases showed the cysts were decreased markedly in size, most of the space around the cysts were replaced bynormal cerebral tissue.Conclusion (1)CTC is simple ,safe and specific for making a final diagnosis of IAC. IACs can be classified into CIAC and NCIAC by CTC findings.(2)Neurosurgical indication for IAC is NCIAC patients with symptoms.
