So thanks to the handful of folks who responded. Some replied that they, too, had not seen this but others reported their anecdotal experience with this unusual entity. There isn’t much in the literature about it.
The surgeon is inclined to treat conservatively as there is no Stener and therefore should scar in.
I should have mentioned (it being apparent on the images I shared) that the whole UCL is a bit edematous and delaminated, as is the RCL….
Thanks again
