There are small nodules/cysts seen at the right uppermost lobe measures 9.6 mm x 7.5 mm 6.7 mm and small mass 31.7 mm x 21.3 mm then at the left uppermost lobe small nodules/cysts are seen measures 21.3 mm x 15.4 mm and 15.8 mm x 15.8 mm. The right upper lobe has small nodules measures 11.7 mm, 7.1 mm, 6.7 mm while at the right middle has small nodules measures 5.0 mm, 6.7 mm, 7.1 mm, 2.9 mm and 7.9 mm.

IMPRESSION: Enlarged right and left lobes - THYROMEGALY Normal isthmus Right uppermost has small mass and small nodules/cysts. Right upper, right middle, right lower lobes has small nodules/cysts. Right upper middle and lower middle lobes- small nodules/ cysts and small mass. Left uppermost has small nodules/cysts. Left upper, left middle, left lower lobes has small nodules/cysts. What does the impression mean? Your answer will be of great help. Thanks
