title: False-positive gray-scale ultrasonography for intra-abdominal abscesses.
abstract: Two patients had convincing mass lesions demonstrated with gray-scale echography and strongly supporting clinical evidence for intra-abdominal abscesses. Neither patient had a lesion at the time of surgery. Although modern echography is an accurate diagnostic method for intra-abdominal abscess, false-positive results can occur.
