Resolution of appendiceal colic following migration of an appendicolith

Abstract

The presence of an appendiceal fecalith should not be considered as a categorical sign of acute appendicitis. The fecalith may, however, be responsible for abdominal pain--right lower quadrant tenderness without associated appendicitis, i.e. appendiceal colic. When a patient presents with right lower quadrant abdominal tenderness, abdomino-pelvic computerized tomography (CT) may establish this diagnosis by demonstrating the presence of the appendicolith but without evidence of appendiceal inflammation or infection. Spontaneous migration of the appendicolith may result in cure. In this previously unpublished clinical case, the CT demonstrates the spontaneous passage of the appendicolith, which coincided in time with the resolution of the abdominal pain syndrome. When a patient presents with typical symptoms of appendiceal colic and CT findings of an appendicolith without appendicitis, appendectomy will certainly relieve the pain. But if the stone passes spontaneously, the need for appendectomy is debatable, particularly in a high-risk patient.
