Accessory Hepatic Lobe-A ‘not so Rare’ Entity
Introduction: Accessory Hepatic Lobe (AHL) is an uncommon developmental anomaly usually asymptomatic and reported as an incidental finding on cross-sectional imaging, laparotomy or autopsy. With increasing number of cases undergoing cross-sectional imaging the detection rate of AHL has increase...

Introduction: Accessory Hepatic Lobe (AHL) is an
uncommon developmental anomaly usually asymptomatic
and reported as an incidental finding on cross-sectional
imaging, laparotomy or autopsy. With increasing number
of cases undergoing cross-sectional imaging the detection
rate of AHL has increased.
Aim: The aim of this study was to assess the incidence
and describe the imaging features of AHL using Computed
Tomography.
Materials and Methods: A retrospective review of CT
images of patients who underwent abdominal CT for
diverse clinical indications was undertaken for detection
of accessory hepatic tissue within the abdomen and pelvis
and the data so obtained was analysed.
One thousand abdominal CT-scans were retrospectively
reviewed for the presence of AHL and when identified,
were further characterized based on their location, volume
and blood supply, wherever possible using existing set of
images.
Results: A total of seven cases with AHLs were detected
during review of 1000 case studies, with an incidence
of 0.7% in our study group. All AHLs were perihepatic
in location. Five of the accessory lobes were connected
to the left lobe of liver by a band of hepatic tissue or a
vascular pedicle and two AHLs were seen arising from the
caudate lobe.
Conclusion: AHL is not as uncommon an entity as was
earlier believed. Awareness regarding this entity and its
clinical significance is important in order to be able to
identify and manage complications arising from it. |
