摘　　要：肺黏液腺癌发病率较低,在胸部CT上可分为2型:结节肿块型、肺炎型,其中以结节肿块型较为多见。结节肿块型肺黏液腺癌与其他非小细胞肺癌难以区分,表现为分布在肺野周围的实性或部分实性结节,伴毛刺、分叶,更容易出现“空泡征”。肺炎型肺黏液腺癌预后不佳,更易发展成弥漫性病变,呈多灶性、多叶性,类似炎症表现,提示沿气道-肺内播散,典型征象包括大片状低密度、低强化的实变、“枯树枝征”等。Pulmonary mucinous adenocarcinoma(PMA)is relatively rare.On chest CT,it can be divided into two types:mass type and pneumonia type.Mass type PMA is more common and is difficult to distinguish from other nonsmall cell lung cancer.It is a solid or partial solid nodule or mass,predominantly located in the peripheral field of the lung with lobulation,spiculation,and more prone“vacuole sign”.Pneumonia type PMA has a poor prognosis and is more likely to develop into diffuse,multifocal and multilobular lesions similar to inflammatory manifestations,indicating dissemination along the airway.Typical signs include large areas of low density,low enhancement consolidation,and“dead tree sign”.
