Current classification system for cancers associated with cystic airspaces are largely divided into four types (I-IV) [1]. This classification system does not provide any prognostic information but rather helps in risk stratification. The growth pattern of these early cystic lesions is quite variable with no stepwise transition between different types. It is important to have timely surveillance in order to check for progression. As noted in Fig 5 and 6 there has been a progression of the bubbly lesion in three years and it was proven to be a lung adenocarcinoma on biopsy. Fig 1-3 are all bubbly lesions of various types which have all been proven to be lung adenocarcinoma. Some of the mimickers are infection, thick wall cysts induced by chemotherapy agents, and also amyloidosis when associated with granulomatous polyangitis.
