Unusual combination of muscular and arterial variations in the upper extremity: a case report of a variant palmaris longus and an additional tendinous portion of the flexor carpi ulnaris together with a persistent median artery

In this report we describe an unusual combination of anatomical variations in the left upper extremity. A rare case of a variant palmaris longus muscle, an unknown variation of the flexor carpi ulnaris muscle and a persistent median artery were discovered during routine anatomical dissection. The anatomical aspects of these variations have been discussed in detail. We also review the clinical literature and presented their possible clinical implications.
