Lung cancer associated with cystic airspace is a rare disease, and the imaging understanding of lung cancer with cystic cavity is still unclear. Little is known in the literature on whether cystic lung cancer is caused by emphysema or ruptured bullae.
We report the case of a 50-year-old female patient after finishing a business trip in November 2021, when another chest CT demonstrated an unexpected reduction in the cyst, with a solid mural nodule on the posterior wall. The airspace of the cyst is only about 13 mm × 12 mm × 6 mm in size. The size of the mural nodule in the posterior wall is about 10 mm × 6 mm × 5 mm. The patient felt anxious due to suspicion of lung cancer. 2.5 months after the last chest CT, she accepted minimally invasive thoracoscopic surgery on the posterior basal segment of the left lower lobe. The postoperative pathology showed benign lesions.
For radiologists, it is important to recognize the process from lung cysts or bullae to LC-CAS, especially the morphological changes of the cyst airspace and the cyst wall, in order to identify the malignant features of lung cysts in time.
与囊性气腔相关的肺癌是一种罕见疾病，对伴有囊性空洞的肺癌的影像学认识仍不明确。关于囊性肺癌是否由肺气肿或肺大疱破裂引起，文献中知之甚少。
我们报告一例50岁女性患者，2021年11月出差结束后，再次进行胸部CT检查时发现囊肿意外缩小，后壁有一个实性壁结节。囊肿气腔大小仅约13mm×12mm×6mm。后壁壁结节大小约10mm×6mm×5mm。患者因怀疑肺癌而感到焦虑。在最后一次胸部CT检查2.5个月后，她接受了左肺下叶后基底段的微创胸腔镜手术。术后病理显示为良性病变。
对于放射科医生来说，认识从肺囊肿或肺大疱到LC-CAS的过程，尤其是囊肿气腔和囊肿壁的形态变化，以便及时识别肺囊肿的恶性特征非常重要。
