Retrocerebellar arachnoid cysts are uncommon intracranial tumors, especially rare in adults. Although asymptomatic in the majority of cases, they may cause a variety of symptoms including convulsions. The causal involvement of these cysts in postictal psychosis, however, remains a topic that is not well-explained in the literature. An 85-year-old Asian man presented with recurrent episodes of convulsions for the last seven months along with preceding headaches and postictal psychotic symptoms. MRI of the head revealed a retrocerebellar arachnoid cyst. He was commenced on symptomatic pharmacological therapy after he refused surgical intervention and remained symptom-free till his discharge from the hospital before being eventually lost to follow-up. This case report focuses on the rare occurrence of a retrocerebellar arachnoid cyst with seizures and postictal psychosis and illustrates the necessity of further case studies and research to identify and explore the potential causal relationship between arachnoid cysts and psychosis.
小脑后蛛网膜囊肿是一种罕见的颅内肿瘤，在成人中尤为罕见。虽然大多数情况下无症状，但它们可能会引起包括抽搐在内的各种症状。然而，这些囊肿与发作后精神病之间的因果关系在文献中仍未得到很好的解释。一名85岁的亚洲男性在过去七个月中出现反复发作的抽搐，伴有先前的头痛和发作后精神病症状。头部MRI显示小脑后蛛网膜囊肿。在他拒绝手术干预后开始进行对症药物治疗，直到出院前一直无症状，最终失访。本病例报告重点关注小脑后蛛网膜囊肿伴癫痫发作和发作后精神病的罕见情况，并说明了进一步进行病例研究和调查以确定和探索蛛网膜囊肿与精神病之间潜在因果关系的必要性。
