A 25-year-old female arrives at the Emergency Department complaining of sudden onset abdominal pain. The pain is intermittent, concentrated in the right iliac fossa, and is rated at a 7/10 intensity. The patient is experiencing nausea and has vomited twice. She reports her last menstrual cycle was 4 weeks ago. An ultrasound of the abdomen shows a whirlpool pattern in the right iliac fossa. What is the probable diagnosis?
