The frequency of vomiting has been increasing progressively over 2 weeks. The vital signs are within normal limits. The examination of the abdomen reveals the presence of a firm mass of approx. 2 cm in length, above and to the right of the umbilicus. The mass is movable, olive-shaped, and hard on palpation.
