A disappearing abdominal mass in a teenage female

Abstract

We present a case of a 17-year-old female who presented to an urgent care for evaluation of a right-sided abdominal mass. Prior to her evaluation, she had undergone advanced imaging and exploratory laparotomy that did not reveal a diagnosis for her symptoms. Our case emphasizes the importance of listening to the patient who persists in describing a particular clinical symptom and highlights the forgotten, yet historically well-known, diagnosis of nephroptosis.
