Many different entities simulating colonic polyps on barium enema examination have been described. Of the extraluminal mimics, round bony structures such as vertebral pedicles are perhaps best known. We describe the cause of a previously undescribed artifact: bone marrow biopsy of the ilium.
钡剂灌肠检查中模拟结肠息肉的许多不同实体已被描述。在腔外模拟物中，诸如椎弓根之类的圆形骨质结构可能最为人所知。我们描述了一种先前未被描述的伪影的原因：髂骨骨髓活检。
