各种类型的粘多糖都可累及心血管系统及全身其他多个系统。在４例经临床特征性症状与体征、ｘ线表现和实验室检查证实为粘多糖病ＩＩＢ型病例的超声显象检查中，发现二尖瓣和主动脉瓣均有不同程度的增厚，二尖瓣前叶左房面有赘生物样回声附着；胰腺均表现有不同程度的增大。由于能够排除其他病变形成的瓣膜赘生物及胰腺病变，可以认为二尖瓣赘生物样回声的形成及胰腺的增大也是粘多糖病内脏受累的表现。 Various types of mucopolysaccharides can affect the cardiovascular system and other multiple systems throughout the body. In 4 cases of clinically characteristic symptoms and signs, x-ray findings and laboratory tests confirmed mucopolysaccharidosis type IIB ultrasound imaging examination showed that mitral and aortic valves have varying degrees of thickening, two Left anterior leaflet mitral valve surface ependymoid attachment; pancreas showed varying degrees of increase. Because of the exclusion of valve neoplasms and pancreatic lesions formed by other lesions, it is believed that the formation of mitral valve-like echoes and enlargement of the pancreas are also manifestations of visceral involvement of mucopolysaccharides.
