Brain parenchymal metastases are brain tumors associated with the extracranial primary systemic tumor. The most common tumors metastasizing to the CNS are tumors of the lung, breast, kidney, and malignant melanoma.
Metastases are most widespread in a hematogenous manner and predilectively affect the white-gray matter interface. The clinical picture and symptoms of these tumors can vary greatly.
A large proportion of patients have asymptomatic and intracerebral metastases (metastases) are found during regular re-staging of the primary tumor. Other clinical presentations may be symptoms of increased intracranial pressure (headache, nausea, vomiting), focal neurological deficit, or new onset of convulsive activity.
Surgery in the area of the posterior pit of the skull requires careful closure of the dura mater to prevent postoperative complications. When caring for patients with brain metastases, not only a good result is important, but also a quick recovery with the possibility of an early return to normal activities of daily living.
