Ischiorectal Abscess in a Child Resulting From Ingested Fish Bone : Case Report

Abstract

The case involved to 12-year-old girl with West syndrome who had had anal discomfort complicated by a high-grade fever for several days. Soon after, a large perianal abscess developed and the patient was referred to our department. A pelvic CT scan revealed a gas density area and a high density, needle-like foreign body in an ischiorectal abscess. The abscess was urgently extirpated and drained A fish bone 2 cm in length, was found in the abscess cavity. A bacterial culture of pus with Batteroides fragilis and Escherichia coli was growing. After draining the abscess, therapy with antibiotics rapidly improved her general condition. Reports of periproctal abscesses due to ingested fish bone are occasionally found in adult cases, and this condition most commonly occurs in males between 40 and 60 years old However child cases are rare. Diagnosis of a foreign body in the anus is easily made on simple digital rectal examination at the first symptom of acute anal pain In a case such as one with a mentally retarded child with vague symptoms, delayed diagnosis will result in deeper penetration of the fish bone and abscess formation. For preoperative diagnosis, a CT scan should be particularly helpful for this condition.
