My niece is 15 yrs. old and has been receiving treatment for Crohns for 6 years. Her disease is getting worse. We took her for a second opinion and have been told that she may not have Crohns after all. Today we found out she has a cyst in her kidney and liver and needs an MRI. She is very anemic and suffers bouts of severe abdominal pain. Any ideas of what this could be?
