Variations regarding cervical musculature have been well documented in the literature, including the presence of a levator claviculae muscle within the lateral neck. This case report presents an example of levator claviculae that was discovered during the prosection of a 98-year-old male anatomical donor. This accessory muscle was located in the left cervical region and originated from the posterior belly of the levator scapulae, traversed along the anterior border of the trapezius, and inserted onto the inferior clavicle. Branches of the cervical plexus were noted to innervate both the levator scapulae and the levator claviculae. This report reviews these cervical anatomical variations and highlights their clinical significance. By presenting this case, we aim to increase awareness of unusual anatomical variations, which may aid in reducing the potential for misdiagnosis or confusion among healthcare professionals.
关于颈部肌肉组织的变异在文献中已有充分记载，包括在颈部外侧存在锁骨提肌。本病例报告展示了在一名98岁男性解剖学捐赠者的解剖过程中发现的锁骨提肌实例。这块副肌位于左颈部区域，起自肩胛提肌的后腹，沿斜方肌前缘走行，并附着于锁骨下缘。发现颈丛分支支配肩胛提肌和锁骨提肌。本报告回顾了这些颈部解剖变异并强调了它们的临床意义。通过展示这个病例，我们旨在提高对不寻常解剖变异的认识，这可能有助于减少医疗专业人员误诊或混淆的可能性。
