일측성 폐침윤을 보인 폐포양 유육종증 1예

A sarcoidosis is a multisystemic granulomatous disorder that has a predilection for pulmonary involvement, and the common radiological findings for the disease are bilateral nodular or reticulonodular patterns. Pseudoalveolar sarcoidosis is a rare presentation of sarcoidosis. The radiological finding is an alveolar pattern that involves or compresses the alveoli by clustered interstitial granuloma. A 58-year-old man was admitted due to incidental findings of a unilateral consolidative lesion as seen on chest radiography. A chest computed tomography (CT) examination showed multiple bronchoalveolar consolidations that were suspicious of a malignancy. However, a percutaneous needle biopsy revealed non-caseating granuloma with an asteroid body that was compatible with sarcoidosis. After one month, the consolidative lesions improved without any treatment. 유육종증은 원인 불명의 전신성 질환으로 폐 침윤은 양측 폐 상엽의 결절과, 양측 흉곽내 임파선 비대가 특징적이나 폐포 병변을 보여 폐렴이나 폐암으로 오인될 수 있는 일측성 폐포양 유육종증은 드문 것으로 알려져 있어 문헌 고찰과 함께 보고하는 바이다.
