55yr 5 5 140 Reason for Exam: Z72.0 TOBACCO ABUSE CT LUNG SCREENING PROCEDURE: Thoracic CT was performed without IV contrast. INDICATION: 40 pack years of smoking. TECHNIQUE: CT scan done according to ALARA (As Low as Reasonably Achievable). FINDINGS: There is linear density seen abutting the right apical pleural surface extending to the right upper lobe where there is a nodular density associated measuring 9 x 6 mm. The remaining lung fields are clear. The heart, vascular and mediastinal structures are normal. The osseous and soft tissue structures are normal. Calcified granuloma is seen in the right lower lobe measuring 4 mm, which is benign. The osseous and soft tissue structures are normal. IMPRESSION: Pleural parenchymal nodular density right upper lobe. Statistically this most likely represents right apical pleural-parenchymal scarring. Is this something to be concerned about?
