Aberrant right gastric vein mimicking hepatic spread of prostate cancer on PSMA-PET/CT

Aberrant Right and Left Gastric Veins as a Cause of Hepatic Pseudolesions: A Report of Three Cases

“…According to Muñoz and Fraum, the ALGV typically drains into the posterior margins of hepatic segments II and III [5]. At the same time, the ARGV is mentioned to drain more often into the posterior margin of segment IV, consistent with the findings documented in all our cases.…”

“…Some authors have described additional clinical significance for aberrant gastric veins; for example, these could act as an alternative route for venous drainage in hypertensive gastropathy in cirrhotic patients or as a direct metastatic pathway for gastric cancer to the left side of the liver [3,5]. Moreover, it is critical to know this anatomical variation in patients planning for gastric or hepatic surgery since this could be a source of accidental hemorrhage, potentially increasing the time of surgery and morbidity [3,5]. More cases like ours should be reported to increase the available evidence on imaging features of aberrant gastric veins in crosssectional imaging studies.…”

Aberrant Vascular Anatomy Associated With Artifactual Focal Avidity in the Liver on PSMA PET

“…This focal avidity was presumably due to an intrahepatic vascular malformation and is different from the cases herein presented, which are located in hepatic segment IVb, with at least 2 associated with an aberrant extrahepatic vasculature. Muñoz and Fraum 5 recently reported a case of focal avidity on PSMA PET in hepatic segment IVb. Similar to our cases, they also demonstrated an anomalous vessel piercing the hepatic capsule and entering hepatic segment IV.…”
