Hydrocephalus may occur as the result of a range of infectious or inﬂammatory processes. The effects of chronic inﬂammation – organiza- tion of the inﬂammatory exudate with scarring or gliosis – can produce obstruction to CSF ﬂow, both within the ventricular system and in the basal cisterns and cortical subarachnoid […]
Raised intracranial pressure is due to the tumour mass, surrounding cerebral oedema and hydrocephalus due to blockage of the CSF pathways. The features of raised intracranial pressure are described in detail in Chapter 3. The major symptoms are headache, nausea and vomiting, and drowsiness. Headache is the most common symptom in patients with cerebral astrocytoma […]
The treatment of AVMs is primarily intended to eradicate the risk of potential hemorrhage. The indications and method of invasive treatment of AVMs require a thorough knowledge of AVM natural history and treatment risk. Treatment risk, particularly surgical risk, is defined by a variety of grading systems, the most popular of […]
The presenting features can be classiﬁed under: • Raised intracranial pressure • Focal neurological signs • Epilepsy. The duration of the symptoms and the progression and evolution of the clinical presentation will depend on the grade of the tumour—that is, its rate of growth. A patient presenting with a low-grade astrocytoma (Grade […]
