Liver Pseudotumor Due to Aberrant Left Gastric Vein: A Case Report

Liver pseudotumors (pseudolesions) pose diagnostic challenges in imaging, often linked to anomalous venous drainage. Notably, aberrant left gastric vein (ALGV) plays a role in segment 2 and 3 pseudolesions. A liver parenchymal pseudolesion due to abnormal venous drainage involving ALGV is highlighted. Understanding hepatic vascular dynamics, exemplified by ALGV-related pseudolesions, aids diagnosis and guides decisions. Further investigating intricate mechanisms underlying these anomalies is crucial. Teaching Point: The recognition of third inflow pathways such as ALGV holds significance in distinguishing hepatic pseudolesions from true lesions.
