Summary
Nervous system metastasis is a common initial sign of hepatocellular carcinoma (HCC). Brain and spinal metastases present with diverse neurological symptoms, often unresponsive to radiation therapy.
Area of Science:
- Neurology
- Oncology
- Radiology
Background:
- Hepatocellular carcinoma (HCC) can metastasize to the nervous system.
- Nervous system involvement is often the initial presentation of HCC.
- Understanding these metastases is crucial for diagnosis and management.
Purpose of the Study:
- To retrospectively evaluate nervous system metastasis in hepatocellular carcinoma patients.
- To characterize the clinical presentation and imaging findings of neurological involvement in HCC.
- To assess the efficacy of radiation therapy for these metastases.
Main Methods:
- Retrospective analysis of 19 patients with nervous system metastasis of HCC.
- Review of clinical presentations, including initial symptoms and neurological deficits.
- Analysis of imaging findings from CT and MRI scans.
Main Results:
- Nervous system metastasis was the initial presentation in 7 of 19 patients.
- Brain metastases occurred in 7 patients, 4 with stroke-like presentations (intracerebral hematomas).
- Spinal epidural metastases (11 patients) caused myelopathy (7) or radiculopathy (4); one patient had clival metastasis with sixth nerve palsy.
Conclusions:
- Nervous system metastasis is a significant and often early manifestation of HCC.
- Imaging features can help differentiate HCC metastases from other causes of neurological deficits.
- Radiation therapy demonstrated limited efficacy in controlling the clinical course of nervous system HCC metastasis.
