Imaging features of myelomatous nodular involvement of the liver
| Publication | Ultrasound | CT | MRI |
|---|---|---|---|
| Mathieu et al5 | Hypodense, enhancing from the periphery to the centre | ||
| Nguyen et al6 | “Target” appearance | Hypodense |
T1 weighted: hypointense outer layer, hyperintense rim, isointense core T2 weighted: hyperintense outer layer, hypointense rim, hyperintense core |
| Kelekis et al7 | “Target” appearance | Enlarged liver without discrete nodules in unenhanced phase |
T1 and T2 weighted: hyperintense Moderate enhancement |
| Ng et al8 | “Target” appearance | Slightly hypodense, mild enhancement |
T1 weighted: slightly hypointense T2 weighted: hyperintense Minimal enhancement |
| Patlas et al9 | Hypoechoic/mixed echogenicity | Hypodense on unenhanced and post-contrast phases | |
| Monill et al10 | Non-enhancing nodules | ||
| Tan et al11 | Arterial enhancement Isodense/mildly hypodense on delayed phase |
||
| Present case | Hypoechoic | Arterial enhancement Isodense on portal venous and delayed phase |
T1 weighted: slightly hypointense T2 weighted: hyperintense Arterial enhancement with contrast washout and capsule appearance on portal venous phase Diffusion-weighted imaging: restricted diffusion |
“Target” appearance: hypoechoic halo surrounding the echogenic/isoechoic core.
