Color Doppler of Meckel ’ s diverticulum : report of two cases *

A 15-year-old boy presenting blood in stools for one month. Four days after the symptoms onset, the patient underwent rectosigmoidoscopy which revealed the presence of stale blood in the rectosigmoid junction. Serum hemoglobin level was 11 mg/dl. History of appendectomy three years before. At color Doppler US, a fixed cystic image with gut signature was observed in the right lower abdominal quadrant, with no sign of parietal hyperemia or inflammation (Figure 2A). The Tc-99m scintigraphy was inconclusive. Laparotomy performed in the next day demonstrated a perforated MD at 30 cm from the terminal ileum, attached to the adjacent bowel (Figure 2B). Anatomopathological study of the surgical Color Doppler US may demonstrate parietal hyperemia in an inflamed MD. The authors describe two cases of complicated MD detected at US, whose findings were different from the cases described in the literature: hemorrhagic MD without parietal hyperemia at color Doppler, and the other, a perforated MD detected at color Doppler US with no sign of inflammation.
