Brain

On this T2 TSE Axial Image the brain tissues, fluid and ventricles return normal signal. The orbits are clearly demonstrated. The brain appears structurally normal.

Meningiomas are a tumour of the meninges (the protective membrane surrounding the brain and spinal cord). They are usually benign (meaning that the cells do not spread). Malignancy is extremely rare and they are slow growing. Symptoms differ according to the site of the Meningioma. In this case eyesight is affected.

Symptoms:
Progressive Visual Loss

MRI
Shows bilateral lesions on the optic nerves.

Multiple sclerosis is a fairly common inflammatory condition which affects the brain and spinal cord. It normally starts in the early adult years of life. Symptons may come and go but sometimes they are persistent.

Symptons:
These are very variable depending on which part of the brain or spinal cord is affected but include dizziness, unsteadiness, muscle weakness or sensory changes like tingling or numbness.

MRI:
Shows several discrete bright areas in the white matter of the brain

Anerysms are swellings or outpouchings in the wall of an artery. They occur at many sites in the body not just the brain. Their importance relates to the small chance of aneurysm rupture. Suitable cases can be treated by filling the aneurysm with metal coils from within the blood vessel/ artery, this causes it to clot or thrombose. Surgery is an alternative means of treatment.

Symptons:
Aneurysms are often asymptomatic unless they are large and pressing on important structures. Sudden severe headache and neck stiffness accompanies aneurysm rupture.

MRI:
Shows an aneurysm in one of the arteries supplying the brain.
