colonoscopy - translumen - cap

I am transcribing a colonoscopy report and the doctor states, "...The cecum was reached and identified.  The light translumen in the right lower quadrant.  The ileocecal valve was noted."

I am having a hard time hearing, "The light translumen in the right lower quadrant."  The light translumen is the difficult part to hear.  This doesn't make sense to me. 

Could this be correct?

(P.S.- he typically leaves verbs out, so it could be - was in the right lower quadrant.  But that still doesn't make sense to me!)

Thank you so much!
