Liver Steatosis Secondary to PRRT With 177Lu-DOTATATE: An Unknown Adverse Effect

PRRT (peptide receptor radionuclide therapy) with Lu-DOTATATE for neuroendocrine tumor has some well-known adverse effects, concerning specially the bone marrow and kidneys. Hepatotoxicity has been rarely reported, and there are no data regarding hepatic steatosis secondary to PRRT. We reviewed upper abdomen CT and MRI and applied radiologic criteria for the diagnosis of hepatic steatosis on 62 patients treated between the years of 2010 and 2017. Two patients already showed radiologic signs of steatosis in the middle of the treatment and through follow-up all patients showed improvement of the steatosis.
