Calcific tendinitis is a common disorder in adults. Although rare, humerus involvement associated with pectoralis major tendon calcification migration has previously been reported in studies that focus on its CT and MRI appearance. We present four cases of intraosseous migration of pectoralis major tendon calcification and their ultrasound features. Calcification migration into osseous structures is associated with cortical erosions, intraosseous calcifications, and bone marrow edema. These findings may be misleading on MRI, where the significant bone marrow and surrounding tissue inflammation may raise concerns regarding neoplasia and lead to unnecessary invasive biopsy. In these cases, echography can be less alarming, enabling the identification of the calcification, its location in the pectoralis major tendon enthesis, and the continuity between the calcification and the typical cortical erosion. Ultrasound features may be diagnostic and might help avoid additional costly imaging studies or invasive biopsy.
钙化性肌腱炎是成人的一种常见疾病。尽管罕见，但以前的研究中曾报道过与胸大肌肌腱钙化迁移相关的肱骨受累，这些研究主要关注其 CT 和 MRI 表现。我们介绍了 4 例胸大肌肌腱钙化的骨内迁移及其超声特征。钙化向骨内结构迁移与皮质侵蚀、骨内钙化和骨髓水肿有关。这些发现可能在 MRI 上具有误导性，其中明显的骨髓和周围组织炎症可能会引起对肿瘤的担忧，并导致不必要的有创活检。在这些情况下，超声检查可能不会那么令人担忧，能够识别钙化、其在胸大肌肌腱附着处的位置以及钙化与典型皮质侵蚀之间的连续性。超声特征可能具有诊断价值，并有助于避免额外的昂贵影像学检查或有创性活检。
