I recently had an Ultrasound. These were the findings:

Visualized portions of the pancreas are unremarkable. Negative
sonographic Murphy's sign. Thin wall nondistended gallbladder
without filling defects. Patent IVC, portal vein and hepatic
veins with normal directional flow and spectral waveforms. Common
bile duct is nondilated. Liver demonstrates a smooth contour with
diffusely increased hepatic echogenicity. Relatively
well-circumscribed 3 cm capsular left hepatic lobe lesion without
demonstrable internal vascularity. There is a large portions of
the right kidney are unremarkable. No ascites or adenopathy.

I had an occasional scratching feeling primarily on my arms, chest and scalp.
