Easily Missed Lung Cancer Associated With Cystic Airspaces

Lung cancer associated with cystic airspaces represents a distinctive subtype of pulmonary malignancies, characterized by the presence of cystic airspaces within or adjacent to the tumor, as identified through imaging studies. The absence of standardized terminology and limited understanding of these malignancies have led to inconsistent descriptions, often referred to as “cancers arising from lung cysts” or “cancers associated with cystic airspaces.” In this article, we present a case of a 77-year-old woman diagnosed with both typical lung cancer and lung cancer associated with cystic airspaces.
