Hyperehancing nodule on right side of liver 4 mm in diameter?

Need MD to interpret. This is a very small lesion but your doctor needs to put this in context to your overall medical condition.
Too small to say. Lesions that are <1cm are difficult to diagnose definitively. In these situations, we typically recommend a repeat imaging test (ct or mri) in 4-6 months. If the nodule is unchanged, it is unlikely to be cancer. If the nodule does grow, then it's appearance can be evaluated and treatment plans made accordingly.
