title: [Papillary process of the caudate lobe--erroneous sonography interpretation as a space-occupying lesion].
abstract: The sonographic appearance of the papillary process separated from the caudate lobe of the liver by a fissure is reported. In 2 out of 5 patients, this variant anatomy mimicked a mass lesion. The papillary process is located dorsal to the left lobe of the liver and in front of the portal vein and common hepatic artery. The echogenicity of the papillary process is identical to liver parenchyma. Knowledge of the sonographic appearance and vascular relationship may help to avoid errors in diagnosis.
