ULTRASONIC APPEARANCE OF THE FALCIFORM LIGAMENT

In transverse liver scans, an echogenic focus was commonly encountered at the junction of the right and left hepatic lobes. This finding was variable in prominence, but could be identified in 22 of 25 patients with otherwise normal livers in whom it was specifically sought. Correlation of ultrasound and CT examinations indicate that these echoes represent the falciform ligament. This normal anatomic structure can be differentiated from an intrahepatic mass by attention to its consistent location and alteration of its configuration by experimenting with the transducer axis during the examination.
