Arachnoid cyst and bipolar disorder: a case report

Abstract

Arachnoid cysts are benign and space-occupying lesions containing cerebrospinal fluid. Their clinical manifestations may vary according to the size of the cyst and the interaction between the cyst and surrounding neuronal structures. Mental disorders rarely accompany the clinical picture and most of the cases remain symptom-free unless determined by radiological examinations accidentally. Although there are some cases reported in the literature about the comorbidity of psychosis and arachnoid cysts, so far no case has been reported about the comorbidity of bipolar disorder and arachnoid cysts.. Here we present a male patient with bipolar disorder associated with an arachnoid cyst in occipital lobe located in posterior fossa and discuss the case with reports in the literature.

Araknoid kist ve iki uçlu bozukluk: Bir olgu sunumu

Öz

Araknoid kistler selim, beyin omurilik sıvısı içeren, yer kaplayan lezyonlardır. Klinik belirtiler kistin büyüklüğü ve komşu nöral yapılarla etkileşimine göre değişkenlik göstermektedir. Klinik görünüme mental bozuklukların eşlik etmesi ender olarak görülmekte, çoğu olgu ise belirti vermemekte, radyolojik incelemeler sırasında rastlantısal olarak tanı konmaktadır. Literatürde araknoid kist ve psikoz birlikteliği ile ilgili vaka bildirimleri bulunmaktaysa da, iki uçlu bozukluk ve araknoid kist birlikteliği ile ilgili bir olgu bildirilmemiştir. Bu olgu bildiriminde iki uçlu bozukluk tanısı ile takip edilen oksipital lobda posterior fossa yerleşimli araknoid kisti söz konusu olan bir erkek hasta sunulmuş ve literatür bilgileri ışığında tartışılmıştır.
