AMARAL, Horacio et al. Detection of neuroendocrine tumors by positron emission tomography-computed tomography with 68Ga-DOTATATE: Report of one case. Rev. méd. Chile [online]. 2009, vol.137, n.4, pp.537-541. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872009000400012.

We report a 74-year-old maie with liver metastases from a neuroendocrine tumor (NET) of unknown origin. Conventionai imaging studies with ultrasound, computed tomography coionoscopy and Positron emission tomography-computed tomography (PET/CT) with 18Flúor odeoxyglucose did not identify the site of orígin of the primary tumor. The patient was submitted for a PET/CT sean with a new radiopharmaceuticai, the somatostatin anaiogue 68Ga-DOTATATE. This new technique demostrated increased focal uptake at the ileocecal valve. This lesión and other two liver metastases were surgically removed. The histopathology and immunohistochemistry analysis confirmed the diagnosis of NET (carcinoid). This case illustrates the advantages of the PET/CT sean with 68Ga-DOTATATE.

Palavras-chave : 6SGa-DOTATATE; Neuroendocrine tumors; Tomography emission computed.
