A 38-year-old woman with bronchioloalveolar carcinoma (BAC) had a slow-growing cavitary nodule for nearly a decade. When she was hospitalized because of pneumonia 9 years earlier, a chest computed tomography scan showed a 1.5-cm cavitary right upper lobe nodule. At 1, 3, and 9 years computed tomography scans showed slow growth of the nodule to 2.4 cm, corresponding to a volume doubling time of 1494 days. Thoracoscopic biopsy and lobectomy were performed. Pathologic analysis revealed a well-differentiated mucinous BAC (T1N0M0). Pseudocavitation in solitary BAC is rare. A longer period of surveillance may be required to rule out malignancy in this setting. Surgical resection remains the mainstay of therapy.
一名38岁的细支气管肺泡癌（BAC）女性患者有一个生长缓慢的空洞性结节近十年。9年前她因肺炎住院时，胸部计算机断层扫描显示右肺上叶有一个1.5厘米的空洞性结节。在1年、3年和9年时的计算机断层扫描显示结节缓慢生长至2.4厘米，体积倍增时间为1494天。进行了胸腔镜活检和肺叶切除术。病理分析显示为高分化黏液性BAC（T1N0M0）。孤立性BAC中的假空洞罕见。在这种情况下可能需要更长时间的监测以排除恶性肿瘤。手术切除仍然是主要的治疗方法。
