Transient hepatic attenuation difference or fat sparing? Aberrant right gastric vein determining a pseudolesion at the border of the IInd/IIIrd liver segments. Review of developmental concepts.

The aberrant right gastric vein (ARGV) is a rare anatomical variation. It can be responsible for unexplained hyperdensities in the hepatic parenchyma on CT scans, also known as third inflow effects. We present two cases sharing similar vascular pattern and slightly different imagistic findings on ultrasound and computer-tomography performed studies.

The Prevalence and Morphology-Wise Demographic Distribution of Ponticulus Posticus on CT Scans-A Retrospective Observational Study.

The ponticulus posticus (PP) is a bony bridge that emerges from the posterior aspect of the superior articular process, to connect the posterior arch of the atlas. It is often associated with neurological symptoms. The aim of this study was to obtain an insight into this malformation, and prevalence in the North East region of the Romanian population.
