A female patient presents with right lower quadrant pain and vomiting. What condition would a pelvic ultrasound be least likely to rule out?

• A. Appendicitis
• B. Pancreatitis
• C. Ovarian torsion
• D. Tubo-ovarian abscess

Answer: (B)

A pelvic ultrasound is primarily focused on the structures within the pelvic cavity, which includes the uterus, ovaries, and surrounding pelvic organs. In cases of right lower quadrant pain and vomiting, it is useful for evaluating conditions such as appendicitis, ovarian torsion, and tubo-ovarian abscess, as these conditions directly involve the pelvic anatomy and can be visualized on an ultrasound. Pancreatitis, on the other hand, is a condition that primarily affects the pancreas, which is located in the upper abdomen, not the pelvic region. While an ultrasound might provide some information about complications of pancreatitis (like fluid collections), it is not specifically designed to diagnose pancreatitis itself or to rule it out effectively. Therefore, in the scenario provided, it is least likely that a pelvic ultrasound would rule out pancreatitis compared to the other conditions listed.
