title: Calcific parasite or surgical miscellany?
abstract: This article highlights the difficulties posed by initial radiological investigations that misleadingly interpreted a linear opacity in the ascending colon of a 2-year-old to be a complicating calcified Ascaris. Final surgical management revealed an unusual cause for the tram tracking effect so pathognomonic of Ascaris infestation. Of interest are the images of the abdominal x-ray, ultrasound scan, and barium study.
