Data of nodules

Cases	Imaging techniques (results)	Total number of nodules (imaging + slicing): size / aspect	Histological diagnosis
1	a: 2.5 cm nodule (LL), FNH b: 1.5 cm adjacent triangular lesion c: not detected d: not detected	a: 2.5 cm, aspect of FNH b: 1.5 cm / yellow c: 5 mm / yellow d: 2 mm / yellow	a: FNH (typical) b: steatotic nodule (type 1–2 lesion) c: steatotic nodule (type 2–3 lesion) d: steatotic nodule (type 2–3 lesion)
2	a: 2.5 cm nodule (LL) probable adenoma	a: nodule difficult to identify from the surrounding tissue	a: partly type 2–3 lesion, partly subtle FNH (type 4 lesion)
3	a: 6 cm nodule (RL), FNH or adenoma b: not detected	a: 6 cm, aspect of FNH b: 5 mm whitish nodule	a: FNH (typical) b: dilatation of thin wall vessels (type 1 lesion)
4	a: 4 cm nodule (LL), probable adenoma b: not detected	a: 4 cm, aspect of FNH b: 1 × 2 cm whitish nodule	a: FNH (typical and telangiectatic type) b: type 2, 3, 4 lesions
5	a: 3.5 cm nodule (III and IV), adenoma or HCC b: not detected c: not detected d: not detected	a: 3.5 cm, aspect of FNH b: 1.5 cm c: 3 mm yellow d: 2 mm hemorrhagic	a: FNH (typical but steatotic) b: FNH (typical but steatotic) c: type 3 lesions d: dilatation of thin wall vessels (type 1 lesion)
6	a: 3 cm nodule (VIII), adenoma or FNH	a: 3 cm, aspect of FNH	a: typical FNH with type 2–3 lesion at the periphery
7	a: 7 cm nodule (V, VI), FNH b: not detected	a: 7 cm, aspect of FNH b: 1.1 × 1.8 cm pale	a: FNH (typical) b: steatotic (type 3 lesion)
8	a: 2 cm nodule (V, VI), suspicion of HCC	a: 2 cm, aspect of FNH	a: subtle FNH (type 4 lesion) with type 2–3 lesion at the periphery

Cases 1 to 7 are women. Letters a, b, c, d identify different nodules for a same case. Roman numbers indicate the segments of the liver. LL: left lobe; RL: right lobe.
