Tiny (presumably fat-containing) umbilical hernia which is so common that half the time we don't mention it.Can't conclude anything about the renal lesion without the full description. If it's one complete thing that has decreased in size, then yes it's benign. If there was a 3.6 cm cystic lesion that has gotten smaller but now has suspicious features, that's a different story.
MRI Renal ResultsAbdominal Wall: Umbilical defect approximately 9mm TRVCan someone explain this to me? Is this a hernia, if so how is this possible?Also originally I received the mri for a renal mass that was first discovered in 2017 of 3.6 cm and on my recent MRI exam is now 1.1 cm? Does this mean it could still be cancerous or most likely benign?
