The patient had a mass in her right upper quadrant that was palpable below the liver; this was the gallbladder.
In healthy individuals, the gallbladder is not palpable. An expanded gallbladder indicates obstruction either within the cystic duct or below the level of the cystic duct insertion (i.e., the bile duct).
The patient’s vomiting was related to the position of the tumor.
