The role of multidetector computed tomography in diagnosis of hepatic pseudolesion

Abstract

1. Introduction Hepatic pseudolesions are imaging artifacts that can mimic or obscure real liver lesions, often due to localized blood flow disturbances. Their detection has increased with advanced imaging techniques like MDCT and dynamic MRI. Accurate identification is crucial to avoid unnecessary tests, biopsies, or misdiagnoses, as pseudolesions may be mistaken for real pathology or hide serious conditions. Identifying liver masses involves analyzing dynamic contrast-enhanced imaging phases, but the liver’s distinct blood flow patterns can lead to pseudolesions, making diagnosis more challenging.2. Aim The aim of this study was to propose a review of hepatic pseudolesions diagnosis using MDCT and explaining means to differentiate these lesions from true parenchymal lesions.1. Patient and Methods PATIENTS: The study was conducted on patients who are referred to the Radiology Department of Alexandria University Hospitals to perform MDCT of the liver for screening or diagnosing focal hepatic lesion.METHODS: All patients were subjected to: • Full history taking .• Clinical examination.• Laboratory investigations:renal function tests (urea and creatinine).• Imaging :ultrasound screening and MDCT triphasic liver while MRI whenever indicated.
