Patient Data

Ultrasound of the right lower quadrant shows a non-compressible, dilated blind-ended tubular structure measuring 9mm in diameter with surrounding inflammation. The target-like appearance of this structure is supportive of the diagnosis of appendicitis, which was confirmed via laparoscopic appendectomy.
