A 72-year-old man had been taking 10 mg/day of prednisone since idiopathic thrombocytopenic purpura (ITP) was diagnosed when he was 60 years old. An interstitial lung shadow was observed on chest X-ray films when he was about 62 years old, and interstitial pneumonia (IP) (chronic-type), etiology unknown was diagnosed. With the progression of honey-comb shadows on the dorsal side of the lower lung fields, cystic changes on the anterior side of the upper lung fields also became more obvious. Slowly progressing IP associated with ITP is very rare. In addition, the chest CT findings of cystic changes on the dorsal side in the lower lung fields and on the anterior side in the upper lung fields are quite interesting.
一名72岁男性自60岁被诊断为特发性血小板减少性紫癜（ITP）以来，一直服用泼尼松10毫克/天。他62岁左右时胸部X光片上观察到间质性肺阴影，被诊断为病因不明的间质性肺炎（IP）（慢性型）。随着下肺野背侧蜂窝状阴影的进展，上肺野前侧的囊性改变也变得更加明显。与ITP相关的缓慢进展性IP非常罕见。此外，下肺野背侧和上肺野前侧囊性改变的胸部CT表现相当有趣。
