Can it be possible to confuse cubital tunnel syndrome with carpal tunnel syndrom?

I suppose as both: Affect sensation in the hand. Some times they present together but the symtoms of one seem to outweugh the other . Other times the lnar and the median nerve have inter connnection in the forearm or hand and what appear to be one is the other or both. This is one reason why nerve studies are often used to clarify clinical impressions.

Yes: I am regularly referred patients for EMG from primary care as ?carpal tunnel syndrome who turn out to have cubital tunnel syndrome so clearly the answer is yes. However careful attention to the anatomical distribution of the symptoms should usually indicate clearly which it is. A few patients have both conditions simultaneously
