Ans:D. Lumbar puncture
Condition is Brain Tumour
- Computerised tomography (CT) scan – this produces a detailed picture of your brain using a series of X-rays
- Magnetic resonance imaging (MRI) scan – this produces a detailed picture of your brain using a strong magnetic field and radio waves
- Electroencephalogram (EEG) – where electrodes attached to your scalp record your brain activity to look for any abnormalities
- Biopsy: If a tumour is suspected, a biopsy may be taken to establish the type of tumour and the most effective treatment.
Lumbar puncture should be performed for the following indications:
- Suspicion of subarachnoid hemorrhage (SAH)
- Suspicion of central nervous system (CNS) diseases such as Guillain-Barré syndrome and carcinomatous meningitis
- Therapeutic relief of pseudotumor cerebri
