When You Hear Hoofbeats, Think of Zebras: An Autobiographical Case Report of Superior Mesenteric Artery Syndrome.

Superior mesenteric artery syndrome (SMAS) is a rare, potentially fatal condition that presents with nonspecific gastrointestinal symptoms. Patients often improve clinically following treatment, but complete symptom resolution is challenging to attain. This case report describes the author's 10-year experience with SMAS following the onset of symptoms at the age of 16 years, as well as sequential diagnoses related to her course of SMAS. Treatment outcomes in the literature, as well as the author's experience with diagnosis and treatment, will be discussed.
