A 45-year-old woman presented to the emergency department with acute worsening of prolonged unexplained nausea, nonbilious vomiting, and mild upper abdominal pain of 4 years duration. Her bowel habits were regular, and there was no history of diarrhea or fresh or altered blood in her stool. On further inquiry, there was no history of facial flushing, excessive diaphoresis, or asthmalike symptoms. Her history was unrevealing; in particular, there was no history of known malignancy. On clinical examination, her vital signs were stable. The abdomen was soft, with no focal tenderness or palpable mass. Routine blood investigations, including complete blood counts, and liver, kidney, and thyroid function tests yielded results that were within normal limits. Her 5-hydroxyindoleacetic acid and chromogranin A levels were not elevated. Initial evaluation with contrast-enhanced CT of the abdomen and pelvis was performed. Subsequently, an indium 111 octreotide scan was performed at the recommendation of the radiologist 1 month after CT (Figs 1, 2).
