Abstract

Delusional infestation is a condition where one believes that he or she has a large parasitic infestation. We present a case with delusion of snake infestation as the only psychotic symptom without any primary psychotic or mood disorder. The site of infestation and the type of parasite involved makes it an unusual clinical presentation.
