A 12-year-old girl had a gradual onset of abdominal detention. A computed tomographic study of the abdomen showed a fluid-filted peritoneal cavity without masses. The fluid was chylous in nature. A lymphoscintigram was performed to evaluate for the site of obstruction or leakage. A positive contrast radiographic pedal lymphogram is shown for comparison. The value of lymphoscintigraphy is illustrated.
