Abstract

We present a case of a patient with treatment resistant hallucinatory experiences
with incidental finding of an arachnoid cyst localized in the posterior infratentorial cranial fossa dorsally
to the cerebellum. Psychological testing revealed significant deficit of cognitive functions to the
level of mild intellectual disability in a person that had previously finished high school with good
grades. A combination of clozapine and lamotrigine led to significant improvement in mood and reduction
of hallucinations, but without improvement in cognitive functions. We also performed a literature
review of previously published case reports or case series of co-occurring posterior fossa arachnoid
cyst and schizophrenia or psychosis or psychiatric symptoms using PubMed search and discuss
some controversies considering their treatment outcome.
