title: Neuroendocrine tumor of the gallbladder with spectral CT.
abstract: Neuroendocrine tumors (NETs) are neoplasms that arise from neural crest argyrophil cells, and often occur to the elderly, female and patients with cholelithiasis. In this case, the female patient was 38 years old and admitted into the hospital for interrupted right upward abdominal pain for 2 years plus aggravated with nausea and anorexia for 1 week. Ultrasound showed gallbladder space-occupying lesions and spectral computed tomography (CT) suggested of retroperitoneal lymph node metastasis. The patient was diagnosed with gallbladder neuroendocrine carcinoma after the surgery.
