Hepatocellular carcinoma presenting as nervous system involvement.
To analyze the clinical features of hepatocellular carcinoma (HCC) in patients with signs and symptoms of nervous system involvement as the initial presentation. Over a period of 11 years (January 1993 to December 2003), 15,008 HCC patients were identified at the Chang Gung Memorial Hospital in Kaohsiung, Taiwan. Amongst them, 42 cases had nervous system involvement, of which six had nervous system involvement as their initial presentation. These six cases were enrolled in this study and their clinical and laboratory data were analyzed. The clinical features of the other 36 HCC cases with nervous system involvement were also analyzed for comparison. The six cases were all males, aged 36-68 years old. The involved parts of the nervous system were the cerebellar hemisphere (one), the frontal lobe (one), the sphenoid sinus, sellar turcica, and cavernous sinus (one), the cervical spine (one), and the thoracic spine (two). Their corresponding neurologic presentations were back pain, headache, consciousness disturbance, visual disturbance, and limb weakness. Whilst three out of six patients presenting with nervous system manifestations were found to have concurrent systemic metastases in other expected sites (lung, bone), three had isolated nervous system involvement even after extensive work up. The associated medical conditions of the six cases included hepatitis B (three), hepatitis C (one), liver cirrhosis (two), portal vein thrombosis (three), and diabetes mellitus (two). All the six died within 9 months after the detection of nervous system involvement. The prevalence of nervous system involvement in HCC patients is 0.28% (42/15,088), with 0.04% (6/15,088) having this as their initial presentation. The prognosis of HCC with nervous system involvement is grave. Their clinical and laboratory data are not unique but the diagnosis could only be confirmed by hepatic and nervous system imaging studies, histopathologic examination, and serum alpha-fetoprotein detection. This consideration should be emphasized especially in areas that are hyperendemic for HCC and if the original focus of metastatic lesion is obscure.
