I have a question. My 4 year old son was presented to the emergency room last Monday with a 104 fever, headache, and stomache. After a CT scan was performed, it was revealed that his appendix was enlarged 3 times the normal size, and he had fluid in his pelvic cavity. They sent him home at midnight because they said the appendix wasn't blocked, so they wanted us to observe him to see if got any worse. He had a follow-up CT scan on Wednesday and his appendix went back to normal size and the fluid had disappeared. My question is this: has anyone ever experiened or heard of something like this before? From what I can find researching the subject, most people that have episodes like this have a return episode, which I do not want to have happen with my child. Any information someone can share with me would be greatly appreciated!
