title: Prevalence of hepatic pseudolesions around the falciform ligament in a paediatric population.
abstract: This study investigated the prevalence and features of hepatic pseudolesions around the falciform ligament in 320 children undergoing contrast-enhanced abdominal multidetector computed tomography. Aberrant venous drainage was investigated using thin-section computed tomography images.  Pseudolesions around the falciform ligament were detected in 63 patients (20%). The longest diameter was in the craniocaudal direction in 41 (65%) patients (lesions). An inferior vein of Sappey supplying the pseudolesions was seen in 11 patients (17%). Thirteen patients of the 63 patients  (21%) with pseudolesions who had a history of extrahepatic malignancy were also examined by ultrasound; in two of the 13 patients the lesions were isoechoic and, in the remainding 11 patients, they were hyperechoic. It was concluded that hepatic pseudolesions around the falciform ligament  occur frequently in the paediatric population on CT images. Detection of the longest diameter in the craniocaudal direction and the presence of an inferior vein of Sappey and fatty infiltration should be sufficient to exclude true lesions and make further evaluations unnecessary.
