Clinical and Radiological Effects of The Treatment Modalities in a Case of Arachnoid Cyst Rupture

Abstract

Traumatic rupture into the subdural space without evidence of hemorrhage of the arachnoid cysts that localized in middle cranial fossa is a rare anomaly. We described the clinical and radiologic findings of a case 24-year-old man who was presented with a ruptured arachnoid cyst of the middle cranial fossa , and produced a subdural hygroma with trauma. Although arachnoid cysts account for 1% of all intracranial space occupying lesions, the association between arachnoid cysts and subdural hygroma is rare and only 23 cases have been previously reported in the literature. There are two procedures used in the surgery, the first is cyst fenestration and the second is a cysto-peritoneal shunt. In this patient although we applied all the possible surgical choices and we couldn't achieve any slightest regression on radiological findings, the patient had full recovery clinically.

Araknoid Kist Rüptürü Olgusunda Uygulanan Tedavilerin Radyolojik ve Klinik Etkileri

Öz

Orta fossa araknoid kistlerin travma sonrası yırtılarak kanama olmaksızın subdural alana açılmaları oldukça nadir görülen bir anomalidir. Travma sonrası subdural higroma gelişen orta fossa araknoid kistli 24 yaşında erkek hastanın klinik ve radyolojik bulguları sunuldu. Araknoid kistler tüm kafa içi yer kaplayıcı lezyonların %1'ini oluşturmaktadır. Araknoid kist sonrası subdural higroma gelişimi oldukça nadir görülmektedir ve literatürde daha önce 23 vaka bildirilmiştir. Cerrahi işlem yapılırken iki yöntem kullanılmaktadır; kistin sisternalara fenestrasyonu ve kistoperitoneal şant takılması. Bu hastada her türlü cerrahi girişimi uygulamamıza rağmen, radyolojik olarak herhangi bir düzelme sağlanamamasına rağmen klinik bulgularında tamamen düzelme sağlandı.
