Table 1 Data of nodules
From: FNH-like nodules: Possible precursor lesions in patients with focal nodular hyperplasia (FNH)
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 |
