The levator claviculae is an uncommon anatomical variant found in the posterior cervical triangle. In this report we present a 78-year-old man with this muscular variation, which was found during gross anatomical dissection. While sites of insertion and origin have been variable, in the present case the muscle originated from the left transverse processes of C3 and C4, and inserted onto the lateral third of the ipsilateral clavicle. Clinical considerations of this variant anatomy are of interest, as they may present in patients as a supraclavicular mass and may also mimic pathology on cross-sectional imaging.
锁骨提肌是在后颈部三角区发现的一种罕见解剖变异。在本报告中，我们呈现了一名78岁患有这种肌肉变异的男性，该变异是在大体解剖时发现的。虽然起止点位置多变，但在本病例中，该肌肉起自C3和C4的左侧横突，止于同侧锁骨外侧三分之一处。这种变异解剖的临床考量值得关注，因为它们在患者身上可能表现为锁骨上肿块，在横断面成像上也可能类似病变。
