Embolization of metastatic neuroendocrine tumor resulting in clinical manifestations of syndrome of inappropriate secretion of antidiuretic hormone (SIADH)

摘要

Complications after hepatic artery embolization are usually minor and transient. We report a patient with pancreatic neuroendocrine tumor with hepatic metastases that repeatedly developed clinical findings of syndrome of inappropriate secretion of antidiuretic hormone (SIADH) with hyponatremia (sodium less than 130 mEq/L), low plasma osmolarity (lower than 275 mOsm/kg) and high urine osmolarity (above 500 mOsm/kg) after every session of hepatic artery embolization.
