A Case of Transverse Myelitis Following Treatment with Atezolizumab for Advanced Hepatocellular Carcinoma.

The results of the IMbrave150 study have led to widespread use of the combination therapy of atezolizumab and bevacizumab as a first-line treatment for unresectable or metastatic hepatocellular carcinoma (HCC). Compared to traditional cytotoxic chemotherapy agents, immune checkpoint inhibitors show a spectrum of side effects ranging from mild side effects such as skin rash to potentially severe systemic effects such as myocarditis. We present a case of transverse myelitis diagnosed during the treatment of HCC with atezolizumab and bevacizumab combination therapy.
