Clinical Presentation and Management of Brain Metastasis in a Sample of Iraqi Patients | Biomedgrid

Brain metastases are neoplasms that originate in tissues outside the brain and spread secondarily to involve the brain [1] This may result either from direct local extension of the primary growth, or from blood born metastases [2]. The intracranial compartment is a common site of metastatic cancer. Between 20 and 40% of patients with systemic cancer developed brain metastasis. Such metastasis can be extra axial in nature (e.g. involving the dura and subdural space, or leptomeninges and subarchnoid space), but most commonly they occur within the brain parenchyma [3]. However, the importance of intracranial metastases is not primarily due to its frequent occurrence, but to the fact that manifestations of metastases affecting the brain are usually more overt and disabling and if untreated tend to be rapidly lethal if compared to metastases to other organs such as lung and liver (in which the incidence of metastases is even higher).
