Clinical features of intracranial metastasis of primary hepatocellular carcinoma with burst diplopia as the first manifestation: a case report

Abstract

Intracranial metastasis of liver cancer is rare, and diplopia as the first manifestation is even more rare. This article aims to introduce a patient with sudden diplopia in a middle-aged man. Physical examination revealed left abductor nerve palsy, craniocerebral magnetic resonance imaging (MRI) showed intracranial metastatic tumor, and positron emission tomography-computer tomography (PET-CT) tracing of the original lesion detected the primary liver cancer. This paper provides clinical data for intracranial metastasis of primary liver cancer and the possible pathogenesis and mechanism of sudden diplopia.
