“…Only few literature sources have described the location of the radial head of fl exor digitorum superfi cialis between the bifurcation of the median in the proximal 1/3 of the forearm, and the fl exor digitorum superfi cialis penetrating the median nerve. [4][5] In this study, we have described the bifurcation of the median nerve into medial and lateral divisions that accommodated an anomalous muscle and then unite in the distal 1/3 of the forearm. The anomalous muscle arises by muscle fi bers from fl exor digitorum superfi cialis and inserted by tendon into fl exor digitorum profundus.…”

“…There is no universal consensus on how to handle incidental imaging findings 81,82 which is not surprising given their scope, variety and complexity 69,83 . Radiologists have created different rating scales to denote their risk of malignancy, mostly for MR and CT imaging of specific tissues in certain clinical situations, but even in such narrow contexts broad consensus is difficult to achieve.…”

Managing uncommon and unexpected findings during neuromuscular ultrasound

One barrier to widespread adoption of neuromuscular ultrasound by clinical neurophysiologists is concern over how to identify and manage non-neuromuscular findings. This review addresses this concern by describing the sonographic appearance of a variety of commonly observed pathologies and anatomic variants in dermal, subcutaneous, bony, glandular, lymphatic, vascular, and other superficial tissues. Additionally, it outlines techniques to ensure proper clinical and ultrasound evaluation of unexpected or uncommon findings. Finally, it highlights strategies to manage unexpected findings, including how to best communicate findings to patients and referring clinicians to avoid unnecessary testing and ensure appropriate follow-up. Ultrasound extends the ability of the neuromuscular sonographer-clinician to contribute to patient care.

“…Different reports have associated a variation in the median nerve with the existence of a vascular alteration such as the persistent median artery (PMA) or an abnormal muscle. Skie et al 7 described the finding of a median nerve crossed by an abnormal muscular fascicle of the flexor digitorum superficialis. Antoni et al 8 found an abnormal muscle that divided the median nerve in the proximal third of the forearm.…”

The median nerve constitutes one of the six terminal branches of the brachial plexus. It descends through the inner part of the arm, and in the forearm through the midline. Once it reaches the wrist, it travels the carpal tunnel and divides into its terminal branches. Different variations have been described regarding its most distal portion in relation to carpal tunnel syndrome, the most frequent neuropathy in the upper limb. We report an anatomical variation in the median nerve and the ulnar artery found in the upper left limb of a female cadaver. The median nerve, in the distal third of the forearm, splits leaving a muscular fascicle interposed between the two branches. The ulnar artery has a superficial course along the entire forearm. In 1977 Lanz grouped the different variations in the median nerve in four sections. Type III (median bifid nerve) was sub classified years later into six subtypes. The present case corresponds to type III of Lanz subtype V (bifid median nerve with abnormal muscular fascicle interposed). Although this nerve variation has been described, the coexistence of a superficial ulnar artery had not been previously reported. Thorough knowledge of median nerve anatomy is of utmost importance to diagnose and treat injuries and entrapment neuropathies affecting this nerve and its major branches in the upper extremity. Furthermore, knowledge of its anatomical variations such as bifurcation of the median nerve or superficial ulnar artery could prevent surgical complications.
