Results
37 patients with pericystic lung cancers and suspicious cystic airspaces were identified from 2017-19. There were 22 females and 15 males with an average age of 72 years. The total number of pericystic nodules, cancers and suspicious cystic airspaces was 44. Here is our analysis of these 44 lesions:
- The average size of cystic airspace on the baseline scan was 21.7mm.
- The number of lesions with a pericystic nodule on the baseline scan was 21. The average size of the pericystic nodule on the baseline scan was 15.5mm.
- The pericystic nodules were characterised into four morphological subtypes based on the classification provided by Mascalachi et a l (1)–Type 1: 41%, Type 2: 12%, Type 3:23.5% Type 4: 23.5% (Figure1,2)
- The number of cystic airspaces that developed pericystic nodule over the serial imaging was 10.
- The average time taken to develop a solid nodule adjacent to the suspicious cystic airspace was 44 months. (Figure 3).
- 14 patients underwent biopsy/VATS which showed 9 Adenocarcinoma, 4 Squamous cell carcinoma, and 1 Small cell cancer.
- 14 patients underwent PET CT and 12 showed high FDG uptake.
- 23 patients had background lung emphysema and 2 patients had pulmonary fibrosis.
