A Large Jackstone Calculus Incidentally Detected on CT Examination: A Case Report With Literature Review

Barbara Brogna, Federica Flammia, Francesco Ciriaco Flammia, Ugo Flammia


A rare case of Jackstone calculus in the bladder that was incidentally detected on a computed tomography (CT) examination in a patient with non-specific abdominal pain is described. Jackstone calculus represents a rare entity characterized by a central dense core with peripheral projections that resembles a childrens toy. It is important to recognize this entity because it is conducive to fragmentation through lithotripsy. Jackstone calculi are usually described in veterinary literature, but they are rare in humans. In human patients, their formations are caused by urinary obstructions.
