急性间质性肺炎——附一例报告

ACUTE INTERSTITIAL PNEUMONIA: REPORT OF A CASE

为进一步提高对急性间质性肺炎的认识及其诊断与鉴别诊断水平，报道１例经临床与病理确诊并成功治疗的急性间质性肺炎（ＡＩＰ）。该病的临床特点是不明病因的暴发起病，并快速进展为呼吸功能衰竭。其病理表现与急性呼吸窘迫综合征（ＡＲＤＳ）相同，但与一般所见的慢性间质性肺炎不难鉴别。该病与ＡＲＤＳ的鉴别多依赖于对病因的认真分析，而且ＡＩＰ经糖皮质激素治疗后的预后可望改善。进一步对本病的病理特征、临床特点加深了解，对提高本病的鉴别诊断、治疗及预后大有裨益。

We report a case of acute interstitial pneumonia (AIP) determined by clinical appearance and pathologic manifestations. The patient was critically ill but survived by intensive treatment. The disease was characterized by fulminate onset and developed to respiratory failture. Its pathologic features as same as those of ARDS, but it is not differentiate AIP from chronic interstitial pneumonia on the basis of etiology. The outcome of AIP was improved by corticosteroid therapy. Relevant literature, history, pathogenesis, pathological features, clinical findings, differential diagnosis, treatment and prognosis of AIP are discussed.
