While tumor lysis syndrome is a relatively common oncologic emergency that may occur spontaneously or resulting from cancer directed therapy, it is relatively unusual occurrence in solid tumors, especially neuroendocrine tumors. It is also particularly rare after hepatic trans-arterial embolization. We report a case of a 60-year-old man who had hepatic trans-arterial embolization for metastatic neuroendocrine tumor of the liver of unknown primary, who developed tumor lysis along with post-embolization syndrome. He received aggressive intravenous fluid resuscitation, allopurinol and rasburicase for his tumor lysis syndrome but subsequently had acute renal failure for which he underwent renal replacement therapy. The patient responded well to treatment with complete resolution of his post-embolization syndrome, tumor lysis syndrome and acute renal failure. Our case report highlights the need to consider tumor lysis syndrome in solid tumors. It should be readily recognized and treated given the associated high risk of morbidity and mortality.
