Abstract
Hepatocellular carcinoma (HCC) is one of the most common primary liver tumors in the world. In the United States, it is very uncommon for the liver mass to spontaneously rupture, especially if it has already been treated with embolization. Prompt diagnosis and treatment are necessary to improve the overall prognosis. Unfortunately, even with treatment, the patient can still rapidly decline. We present a case of a patient who was diagnosed with HCC and received treatment with transarterial radioembolization (TARE) with yttrium-90 (Y90). Despite this, the patient's liver mass grew and spontaneously ruptured. Although the patient received additional embolizations for his mass, he still deteriorated and eventually expired.
