Which means nothing, you have a pre-clerkship anatomy course director using archaic and obscure terminology that is extremely rarely used (and arguably incorrect, but we don't have to debate etymology). You will never see this used clinically or in any major anatomy textbook. As you are a medical student you should be familiar with accepted references for anatomy. In case you're not here are some: Netter's anatomy (most commonly used clinical anatomy text): caval foramen. Gray's anatomy: inferior vena cava opening. eAnatomy: caval foramen. Your other clue is in ChatGPT's response: >The term "caval hiatus" is typically used in reference to human anatomy, specifically the anatomical structure known as the "caval opening" or "caval foramen.".... If you ask Claude the same question using 'caval foramen': >The caval foramen, also known as the foramen of vena cava, is located at the level of T8 vertebra in the thoracic region of the vertebral column. Specifically... Some friendly advice as you seem to be early in your medical training: 1. When an attending (in this case two) corrects you, you're probably wrong. Your next step should be to confirm your knowledge not retort with "it's what I was taught". 2. Never say a "major medical school" in Canada (where I also graduated from) which implies there are tiers. Unlike the US, all Canadian medical schools and (almost all) residency programs are excellent.
