Intraparenchymal Hemorrhage due to Brain Metastasis of Hepatocellular Carcinoma
Although extrahepatic metastases from hepatocellular carcinoma (HCC) are present in only 5-15% of cases, they are certainly factors associated with poor prognosis. The main sites include lung, lymph nodes, bones, and adrenal glands, in descending order. Metastasis in the central nervous system is extremely rare, and the incidences vary from 0.6 to 1.7%. We report a case of a 54-year-old man pre...
متن کاملMetastasis and Circulating Tumor Cells
Cancer is a prominent cause of death worldwide. In most cases, it is not the primary tumor which causes death, but the metastases. Metastatic tumors are spread over the entire human body and are more difficult to remove or treat than the primary tumor. In a patient with metastatic disease, circulating tumor cells (CTCs) can be found in venous blood. These circulating tumor cells are part of the...
متن کاملDNA methylation of tumor suppressor and metastasis suppressor genes in circulating tumor cells.
BACKGROUND Circulating tumor cells (CTCs) are associated with prognosis in a variety of human cancers and have been proposed as a liquid biopsy for follow-up examinations. We show that tumor suppressor and metastasis suppressor genes are epigenetically silenced in CTCs isolated from peripheral blood of breast cancer patients. METHODS We obtained peripheral blood from 56 patients with operable...
متن کاملHemifacial spasm associated with intraparenchymal brain stem tumor.
Hemifacial spasm (HFS) is characterized by paroxysmal bursts of involuntary clonic and tonic activity in muscles innervated by the facial nerve. Idiopathic HFS is hypothesized to be a result of microvascular compression of the facial nerve at its root exit zone in the brain stem. Symptomatic (secondary) HFS is usually caused by compression of the facial nerve’s root exit zone. Whether HFS can a...
متن کاملNavigation-guided endoscopic biopsy for intraparenchymal brain tumor.
To evaluate the efficacy of intraparenchymal brain tumor biopsy using endoscopy and a navigation system (navigation-guided endoscopic biopsy) as a diagnostic tool, a case series of intraparenchymal tumor biopsies was reviewed. Navigation-guided endoscopic biopsy was applied in 9 cases, stereotactic needle biopsy in 16 cases, and open biopsy with or without navigation system in 34 cases. In all ...
