胸部结节病的X线征象已为人所熟知,但对其不常见之表现则多不熟悉,且易于发生混淆,本文着重讨论了胸部,包括骨骼、胸膜、纵隔、肺门、支气管、肺实质和心血管在内的结节病不典型的X线表现,为临床诊断提供了有价值的资料。【骨骼病变】X线所见的骨骼受累常见于结节病的慢性阶段,一般伴有皮肤、淋巴或脏器病变,发生率约为3%(1～13%)。骨骼病变常无临床症状,最多见于手足的短管状骨,其他骨骼则较少见。骨骼病变的X线征象较为典型,可分为3型: (1)弥漫性骨髓浸润伴骨小梁吸收,产生圆形或卵圆形骨质疏松区;
X-ray signs of chest sarcoidosis are well known, but unfamiliar to their uncommon manifestations and prone to confusion, this article focuses on the chest, including the bones, pleura, mediastinum, hilar, bronchi, lung parenchyma And cardiovascular, including atypical X-ray findings of sarcoidosis, provide valuable information for clinical diagnosis. Skeletal Lesions X-ray findings of bone involvement are common in the chronic stage of sarcoidosis, and are commonly associated with skin, lymphoid or visceral lesions at a rate of about 3% (1 to 13%). Often no clinical symptoms of skeletal disorders, most of the short bones found in hand, foot, other bones are rare. X-ray signs of skeletal lesions are more typical, can be divided into 3 types: (1) diffuse bone marrow infiltration with trabecular absorption, resulting in round or ovoid osteoporosis area;
