Formas clinicas de presentacion en tumores cerebrales

Central nervous system neoplasias may be located at the skull, meninges, vascular structures, pituitary gland, cranial nerves, choroid plexus, and the brain parenchyma. In infants and children, most of these tumors are located in the posterior fossa and their malignancy rate is high. In contrast, most intracranial tumors in adults are located at the supratentorial comparment. Intraaxial tumors tend to diffusely spread within the brain parenchyma while extraaxial tumors most often cause symptoms due compression of neighbouring structures. Most intracranial tumors show a slowly growing pattern, and its grow cause reduction in the size of other structures of the cranial vault (brain parenchyma, CSF spaces, and so on). Neurological signs as well as signs and symptoms related to intracranial tumors apper when the normal relationship between the volume occupant by theses structures is lost. Clinical manifestations include focal neurological signs as well as signs and of increased incranial pressure. Tumors most frequently causing specific clinical symptoms include: craniopharyngioma, acustic nerve neurinomas, pituitary adenomas, brainstem gliomas, and pineal germinomas. In this review, we describe the clinical syndromes caused by the most common neoplasms of the central nervous system.
