Ultrasound documentation of spontaneously resolving appendicitis.

Diagnostic ultrasound has been reported to be a highly specific technique for the confirmation of acute appendicitis. The authors report the case of a 27-year-old male who presented with clinical, laboratory, and classic ultrasound findings indicating early acute appendicitis. The patient's condition resolved spontaneously without operative intervention, and repeat sonography 2 weeks later was entirely normal. Ultrasound examination may allow documentation of spontaneously resolving appendicitis.
