Her temperature is 37C 98.6F , respirations are 16min, pulse is 78min, and blood pressure is 12298 mm Hg. Physical examination is normal, and she says that her pain has subsided. The urgent care provider suspects she has cholecystitis, so she undergoes a limited abdominal ultrasound to confirm it. However, no evidence of cholecystitis is seen with ultrasound, but adenomyomatosis of the gallbladder is incidentally noted. The patient has no clinical features suspicious for malignancy.

Given the benign nature of this incidental finding and resolution of symptoms, no further evaluation or treatment is required at this time. The next best step is option E.E: No further treatment required
