The radiological features of 20 surgically proven thoracic disc protrusions are reviewed. In 15 (75%), characteristic plain film changes were found to be very helpful in making the correct diagnosis. Calcified disc material in the spinal canal was clearly demonstrated in 11 (55%) cases, and this, in association with linear calcification in the adjacent disc space, has been shown to be diagnostic of the condition. At myelography, central protrusions (55%) were found to be predominant, while lateral protrusions were uncommon. The differential diagnosis of a calcified lesion in the spinal canal includes thoracic disc protrusion, osteochondroma and meningioma.
回顾了20例经手术证实的胸椎间盘突出症的放射学特征。15例（75%）发现特征性的平片改变对做出正确诊断非常有帮助。11例（55%）病例中椎管内钙化的椎间盘物质清晰可见，并且已证明其与相邻椎间盘间隙的线状钙化一起可诊断该病。脊髓造影显示中央型突出（55%）占主导，而外侧型突出不常见。椎管内钙化病变的鉴别诊断包括胸椎间盘突出症、骨软骨瘤和脑膜瘤。
