From Mimic to Diagnosis: Primary Lung Adenocarcinoma Presenting as Peripheral Airspace Opacities Mimicking Organizing Pneumonia
Year: 2025

Study design: Case Report
Abstract: Lung adenocarcinoma may occasionally present with radiographic features resembling organizing pneumonia (OP), resulting in diagnostic uncertainty, delayed recognition, and the risk of inappropriate management. We present a case of a 77-year-old man with diabetes mellitus, hypertension, and ischemic heart disease who developed bilateral pulmonary infiltrates. Radiological findings initially suggested OP; however, histopathological examination revealed a moderately differentiated mucinous adenocarcinoma favoring a primary lung tumor. This case underscores a significant diagnostic pitfall and highlights the necessity of histological confirmation when encountering atypical radiologic features.
