CTICasesBenign Subsolid Nodule from Lymphoid Hyperplasia and Fibrosis
Imaging findings
CT chest shows a stable subsolid pulmonary nodule measuring over 5 mm. Pathology of the resected nodule shows a benign combination of lymphoid hyperplasia and focal interstitial fibrosis.
Key takeaways
Although subsolid nodules are highly suspicious for adenocarcinoma spectrum, a minority can represent benign inflammatory or reactive processes. Prior CT scans confirming long-term stability are helpful to avoid unnecessary surgical resections of benign lesions.
