We present a multiseptated mesenchymal hamartoma of the liver in a 10-year-
old male patient, a rare benign tumor of childhood. The characteristic ultr
asound and CT appearances of this unusual tumor are reviewed. A single sept
al calcification associated with this tumor was demonstrated, an associatio
n which has not previously been repotted. The differential diagnosis for cy
stic liver lesions is discussed in detail. (C) 2000 Elsevier Science Ltd. A
