In rare instances, stroke may precede a diagnosis of cancer and be the first clinical evidence of an underlying malignancy.Cerebral infarction mostly complicates lymphomas, carcinomas, and solid tumors. Malignancy-related thromboembolism can present as acute cerebral infarction, nonbacterial thrombotic endocarditis and migratory thrombophlebitis. It is(More)
An intracranial aneurysm with a diameter larger than 25 mm is considered a giant aneurysm (GA), and represent about 3-5% of all aneurysms. They are divided into two forms, specifically saccular and fusiform. Fusiform aneurysms are rare, making up only 1% of all intracranial aneurysms. They frequently involve the internal carotid artery (ICA) or the basilar(More)
BACKGROUND Anaplastic astrocytoma (AA; WHO grade-III) patients determination of prognostic factors helps generating multimodal therapy protocols. For this purpose, in the Baskent University, Adana Medical Research Center, specific characteristics of AA patients who have surgery were retrospectively investigated and factors which affect prognosis has been(More)
