malignant conditions ( BRAIN TUMOURS)
DEFINITION
brain tumours are space occupying lesions within cranial cavity, taking up space that should be occupied by normal cranial contents and raise intracranial pressure
CLASSIFICATIONS OF BRAIN TUMOURS
oligodendromas arise from the oligodendrocytes.
meningiomas arise from the meninges
cranial nerve tumours are found in cranial cavity
metastatic tumours spread to the brain from tumours elsewhere in the body
glandular tumours include pituitary adenomas and pineal tumours
blood vessel tumours include haemomangiomablastomas and angiomas
congenital tumours include cysts and cranio pharyngioma
CLINICAL MANIFESTATIONS
headache
dizziness
fatigue
inability to speak or understand language
blurred vision
seizures
PATHOPHYSIOLOGY
Brain tumor can form in the brain cells or it can begin elsewhere and spread in the brain. as the tumor grows, it creates pressure on and changes the functiuon of surrounding brain tissue.
DIAGNOSTIC TESTS
The diagnosis of brain tumour is made on the clinical picture as well as on the results of CAT scanning
A stereoctic biopsy may be done to obtain tissue samples
Other studies such as cerebral angiography and MRI scanning may be done to pinpoint the exact position and nature of the tumour
MANEGEMENT
Surgical removal of the tumour is done via a cranitomy. Prophylactic anti-convulsants are prescribed postoperatively
Chemotherapy- cancer chemotherapy may be used on its own or in combination with surgery or radiation
Surgical removal- removal of the tumour is done via a craniotomy
NURSING MANAGEMENT
Close monitoring of neurological status for any sudden increase in intracranial pressure
appropriate supportive care and prevention of the complications of immobility
appropriate care with regard to surgery, radiation therapy or chemotherapy
approprate support for both patient and family
