15-year-old male with history of hepatoblastoma. Mass seen on recent liver ultrasound. Postsurgical changes in the liver related to what appears to be a right hepatic lobe resection with compensatory hypertrophy of the remaining left hepatic lobe which demonstrates cirrhotic liver morphology with sequela of portal hypertension including portosystemic varices and splenomegaly. Along the inferior aspect of the left hepatic lobe there is a round lesion measuring 2.8 cm x 2.4 cm (series 7, image 40) which contains a central scar and demonstrates heterogeneous T2 hyperintense signal with restricted diffusion as well as enhancement which persists on the delayed 3 minute phase sequences. No additional hepatic lesions are evident.Splenomegaly as above measuring 20 cm. No splenic masses.The right kidney is located in the right upper quadrant beneath the diaphragm. Otherwise the kidneys appear normal with no hydronephrosis or intrarenal solid masses. There are bilateral multiple focal subcentimeter intrarenal T2 hyperintense foci most compatible with benign cysts.The imaged bowel is normal. No lymphadenopathy.
1. Postsurgical changes in the liver with cirrhotic liver morphology and sequela of portal hypertension.2. Lesion in the remnant left hepatic lobe demonstrates imaging features suggestive of focal nodular hyperplasia. If further evaluation is warranted, the patient may return for a hepatocyte specific phase post contrast MRI free of charge for further evaluation. 3. Findings most compatible with benign subcentimeter renal cysts.
