This case report shows that Munchausen's syndrome can present as rectal foreign body insertion. Although the presentation of rectal foreign bodies has frequently been described in the medical literature, the insertion of foreign bodies into the rectum for reasons other than sexual gratification has rarely been considered. A 30 year old, unmarried Caucasian male presented with a history of having been sexually assaulted five days earlier in a nearby city by a group of unknown males. He reported that during the assault a glass bottle was forcibly inserted into his rectum and the bottle neck broke. On examination, there was no evidence of external injury to the patient. Further assessment lead to a diagnosis of Munchausen's syndrome. The rationale for this is explained. A description and summary of current knowledge about the condition is also provided, including appropriate treatment approaches. This case report is important because assumptions regarding the motivation for insertion of foreign bodies into the rectum may lead to the diagnosis of Munchausen's syndrome being missed. This would result in the appropriate course of action, with regard to treatment, not being followed. It is suggested that clinicians consider the specific motivation for the behaviour in all cases of rectal foreign body insertion, including the possibility of factitious disorder such as Munchausen's syndrome, and avoid any assumption that it has been carried out for the purpose of sexual gratification. Early involvement of psychiatrists is recommended. Cases of Munchausen's syndrome presenting as rectal foreign body insertion may be identified and addressed more effectively using the approach described.
