TY - JOUR T1 - Cut it out or wait it out? Case series of middle fossa arachnoid cysts presenting with psychiatric symptoms and a discussion of the ethics of neurosurgical management JF - General Psychiatry JO - Gen Psych DO - 10.1136/gpsych-2021-100523 VL - 34 IS - 6 SP - e100523 AU - Petrus Johannes Steyn AU - Leigh Luella Van den Heuvel Y1 - 2021/12/01 UR - http://gpsych.bmj.com/content/34/6/e100523.abstract N2 - Arachnoid cysts have been linked to neuropsychiatric morbidity. We describe two patients presenting with dissociative and manic symptoms believed to be associated with middle fossa arachnoid cysts. They were managed medically and remitted eventually, but symptoms were resistant. We briefly review the literature to discuss mechanisms by which cysts could cause symptoms and consider whether neurosurgical management would be appropriate. Although neurosurgery can be considered, its role is currently limited by practical and ethical considerations. ER -
