Although foramina in the scapula are a rare occurrence, they produce radiolucent defects that simulate those related to skeletal metastasis or multiple myeloma. In order to define the typical location and appearance of these foramina, we initiated a radiographic and pathologic examination of macerated modern and ancient scapulae. Of 93 macerated scapulae that were examined, foramina were observed in 27 specimens (29%). These occurred at four sites: at the superior border of the bone at its junction with the coracoid process, caused by ossification of the superior transverse ligament (21 specimens); in the body of the bone inferior to the scapular spine, resulting from a disturbance in ossification during fetal development (five specimens); in the superior fossa, as a clasp-like defect (one specimen); and, at the superomedial border above the scapular spine (one specimen). The radiographic features of these foramina were compared to those produced by normal vascular channels, anatomic thinning of the bone, and skeletal metastasis or multiple myeloma. Knowledge of the typical appearance and site of scapular foramina assures accurate diagnosis.
尽管肩胛骨孔罕见，但它们会产生透亮缺损，类似于与骨转移或多发性骨髓瘤相关的缺损。为了明确这些肩胛骨孔的典型位置和表现，我们对经过浸软处理的现代和古代肩胛骨进行了影像学和病理学检查。在检查的93块浸软肩胛骨中，27块标本（29%）观察到有肩胛骨孔。这些肩胛骨孔出现在四个部位：在骨与喙突连接处的上缘，由上横韧带骨化所致（21块标本）；在肩胛冈下方的骨体部，因胎儿发育期间骨化紊乱形成（5块标本）；在冈上窝，呈扣状缺损（1块标本）；以及在肩胛冈上方的内上缘（1块标本）。将这些肩胛骨孔的影像学特征与正常血管通道、骨的解剖变薄以及骨转移或多发性骨髓瘤所产生的特征进行了比较。了解肩胛骨孔的典型表现和部位可确保准确诊断。
