Utilidad del PET/CT con análogos de somatostatina marcados con Ga68 en el diagnóstico de síndrome de Cushing secundario a tumor neuroendocrino pancreático / Pancreatic neuroendocrine tumor diagnosed with positron emission tomography/ct scan (PET/CT): report of one case

ABSTRACT

We report a 28 years old woman consulting for weight gain, progressive muscle weakness and appearance of facial plethora. Laboratory showed high cortisol and ACTH levels. Magnetic resonance of sella turcica was normal and an abdominal magnetic resonance showed a pancreatic mass, suggestive of a neuroendocrine tumor. A PET/CT with somatostatin analogues demonstrated an intense over-expression of somatostatin receptors in the tumor. The patient was subjected to a pancreatectomy and the day after surgery, ACTH levels decreased to less than 5 pg/ml. The patological study of the surgical piece showed a neuroendocrine carcinoma. The patient had a good postoperative evolution.
