[|Human|] My 14 year old son woke up yesterday throwing up and fever. He had fever most of the day. I took him to the dr today and he had a ct scan to rule out appendicitis. The ct scan states appendix not seen but he has swollen lymph nodes and free fluid in his pelvis... Radiologist told us to not let him eat anything for the rest of the day and see dr again tomorrow.. Should I be concerned
[|AI|]  Hi, thank you for choosing Chat Doctor. Sometimes the appendix will not be visualized by USG or CT, it is mostly a clinical diagnosis and as he has lymph nodes and free fluid it can also be mesenteric lymphadenitis. In such cases we keep the patient nil by mouth, start Iv antibiotics and observe periodically, most of them respond conservatively, in case the patient doesn't respond or shows signs of perforation surgical management is required. Hope this has been helpful to you, kindly feel free to contact again for any queries. Kindly rate the answer if so. Take care.  Chat Doctor.
