Four patients with malignant fibrous histiocytoma of bone (MFH-B) metastasizing to brain are reported. In two cases, signs of cerebral involvement developed between 4 and 28 months after diagnosis. Both patients had known pulmonary or bony metastases. As a consequence of this experience, two further patients were subsequently identified, one with a definite cerebral metastasis and one who had a...

Brain metastasis is one of the most deadly types of metastasis, frequently seen as a result of cancer spread from lung cancer, breast cancer and malignant melanoma. A key cellular structure in controlling brain metastasis is the blood-brain barrier (BBB). The BBB is known to protect metastatic tumour cells from chemotherapy and antitumor immunity. On the other hand, the BBB is also a key cellul...

Thyroid cancer is not a common primary cancer causing intracranial metastasis. Here we report a 74-year-old woman with magnetic resonance imaging (MRI) demonstrating a 4 cm round, heterogeneously enhancing mass in the trigone of the right lateral ventricle. Systemic screening by computed tomography (CT) examination detected a 20 mm nodule with calcification in the thyroid, multiple well circums...

Cerebral venous sinus thrombosis (CVST) is an infrequent disease (representing around 1% of all strokes) manifested by clotting of blood in cerebral venous or dural sinuses as well as cortical veins. Herein, we describe an unusual case of malignant melanoma presenting with CVST in whom the diagnosis of CVST was suspected on the basis of clinical findings along with brain CT scan, and finally wa...

Brain metastasis of differentiated thyroid cancer (DTC) often is detected during treatment of other remote lesions. We examined the prevalence, risk factors and treatment outcome of this disease encountered during nuclear medicine practice. Of the 167 patients with metastasis to lung or bone treated 1-14 times with radioactive iodine (RAI), 9 (5.4%) also had lesions in the brain. Five were male...

INTRODUCTION Homonymous quadrantanopsia results from retrochiasmal lesions in the visual pathway. Invasive mole is a benign tumor that arises from myometrial invasion of a hydatidiform mole via direct extension through tissue or venous channels. Cerebral metastasis of invasive mole is rare and there has been no report demonstrating homonymous quadrantanopsia as the first manifestation of metast...

PURPOSE Patients with central nervous system (CNS) metastases were excluded from bevacizumab trials following a case of fatal cerebral hemorrhage in a patient with hepatocellular carcinoma in 1997. Safety information for bevacizumab-treated patients with CNS metastases was reviewed to determine whether general exclusion of these patients from bevacizumab treatment is still justified. EXPERIME...
