Patient Data

Age: 55 years
Gender: Male

A well defined solitary pulmonary nodule of soft tissue density is visible in the right lower lobe. Prior examinations confirmed it as a hamartomatous mass. 

Smaller, symmetrical, ill-defined nodular shadows are visible on both sides between the anterior aspect of the 5th and 6th ribs. Unlike the SPN these shadows have an ill-defined medial border, while the lateral border is sharp.
