Sonography of the healthy feline jejuno-ileal junction
This is a very niche observation but something that I’ve not seen described elsewhere. In cats without any evidence of gastrointestinal disease there is often an asymmetrical thickening of the small intestinal mucosa at the jejuno-ileal junction. This is located between 1.5 – 4.0cm proximal to the ileo-caeco-colic junction.
Before I realised that this is normal for many cats, I’ve often interpreted this as potentially pathological.
