The correct answer is E.
The patient has symptoms consistent with carcinoid syndrome. Elevated levels of 5-HIAA in the urine confirms this diagnosis. A cardiac echo is helpful in evaluating the tricuspid insufficiency or pulmonic valve stenosis (TIPS) associated with this syndrome. Furthermore, a chest/abdominal CT or liver ultrasound may identify either a bronchus or liver tumor metastasis responsible for this syndrome’s manifestations. Keep in mind that neuroendocrine tumors elsewhere may secrete vasoactive substances. Carcinoid syndrome only becomes clinically manifest when these hormones bypass or overwhelm the liver (escaping hepatic degradation.)
