CTICasesPulmonary Adenocarcinoma Mimicking Lymph Node
Imaging findings
Initially appeared as a rectangular, nodular opacity on axial imaging, potentially mistaken for an intrapulmonary lymph node. Subsequent follow-up scans showed interval growth, irregular margins, and spiculation.
Key takeaways
Be cautious about overcalling small, flat, or disc-shaped opacities as intrapulmonary lymph nodes. Utilize multiplanar imaging (sagittal/coronal) to assess true nodularity and shape.
