Abdominal pain is a very common presentation in the emergency department (ED). The pain is often well-characterized and leads to the diagnosis, but often, the presentation is vague and nonspecific. Superior mesenteric artery (SMA) dissection is a rare cause of abdominal pain that presents with nonspecific epigastric pain and is common in males, middle age, and patients of Asian descent. A high index of suspicion is usually helpful with imaging modalities such as computer tomography (CT) scan and ultrasonography in experienced hands. A prompt diagnosis is vital to managing this disease which may range from non-surgical intervention with supportive therapy to invasive endovascular procedures and surgery. Here, we report a case of an isolated SMA dissection presenting with vague abdominal symptoms and highlight the need to explore the vascular etiology of abdominal pain as their diagnosis is often difficult and may result in irreversible bowel injury when missed.
