Pica and the radiologist – beyond the radiology report … digging deeper

Pica is a psychological disorder of intentional and craving consumption of non-nutritive substances over a period of time. This is seen at an age when such a behavior is developmentally inappropriate. Substances such as wall paint, soil, hair, and feces have been reported as being consumed. Complications of this condition may range from being self-limiting to life-threatening. Radiological examinations play a crucial role in the diagnosis and management of this condition. We present a case of a 9-year-old boy who presented with chronic abdominal pain with history of persistent consumption of pencil erasers. Abdominal radiographs showed radio-opaque foreign bodies, and etiological diagnosis was made when the radiologist obtained a detailed history from the patient's mother. We also discuss the radiographic evaluation of the pencil eraser and the reason why it is densely radio-opaque.
