At 4 months old, babies are supposed to be happy and healthy. They are starting to roll over, hold their head up, grasp things and put them in their mouth and more. My sister just sent me a picture of my niece who turned 4 months last week (on R) and she is doing all of these things, but, unfortunately, not all 4 month olds are this healthy.
This little guy was brought in by his mom and concerned family over swelling in his side. He was a happy kid, smiling and active and never cried, but on exam, I found a hard mass throughout his abdomen. An ultrasound showed that the mass was coming from his kidney, making the diagnosis of Wilm’s tumor the most likely.
