AbstractAccessory liver lobe (ALL) is a rare congenital anomaly of the liver and is related to the focal excessive development of liver tissue. Accessory liver lobe torsion (ALLT) is a rare condition that can present with acute abdominal pain. Delay in diagnosis can lead to life-threatening complications such as sepsis and systemic inflammatory response syndrome. Imaging methods, especially computed tomography (CT), are of great importance for prompt diagnosis of acute abdominal pain causes, and CT images should be carefully examined. Herein we present a case of ALLT that was occurred due to Morgagni hernia in a 54-year-old male patient who presented with acute abdominal pain. Contrast-enhanced thoracoabdominal computed tomography (CT) was performed and CT demonstrated the Morgagni hernia and herniation of the accessory liver lobe into the hernia sac. CT showed decreased contrast-enhancement in the accessory liver lobe, compatible with ischemia. We also aimed to emphasize the clinical and CT imaging findings of ALLT.Copyright © 2020 Elsevier Inc.
