General Inspection
During the general inspection of the cranial nerves, we should look for whether the patient has any ptosis, abnormal eye movements and facial asymmetry. We should also inspect for whether there are any neuro-cutaneous features (for example in patients with tuberous sclerosis and neuro-fibromatosis), syndromal features etc.

A. Clinical manifestations The clinical features of CSF shunt infection can be quite variable and depend on the pathogenesis of the infection, organism virulence and type of shunt. The most frequent symptoms are headache, nausea, lethargy, fever and change in mental status. Pain, often related to infection at the peritoneal or pleural endings of the…

Measuring the visual acuity of each eye is the first step of the neuro-ophthalmic examination. It should be carried out on every patient presenting with an ocular symptom. Distant visual acuity (at 6…
This patient did not have any recent ocular symptoms but was noted to have significant right eye ophthalmoplegia during examination, whilst the left eye movements were completely normal. There was no double vision upon testing. Whilst one would need to consider a combined third, fourth and sixth nerve palsy in a patient with unilateral opthalmoplegia,…
A. Clinical Manifestations The classic triad of fever, headache and meningeal irritation (neck stiffness) sometimes do not occur altogether. Occasionally, patients may also have altered sensorium. Meningitis can be classified into acute, subacute, and chronic meningitis. Acute meningitis is characterized by onset of symptoms over the course of hours to up to several days. Subacute…
A middle-aged woman was admitted with drowsiness, weakness of all four limbs and visual impairment. Physical examination revealed that the patient had bilateral complete ophthalmoplegia, generalized weakness and spasticity,with brisk reflexes and bilateral upgoing plantar reflexes. A hyper-intense lesion at the level of the midbrain was noted on cerebral MRI (Figure 1). Cerebro-spinal fluid examination…
This is a collection of curated and illustrated 5-minute videos demonstrating common neurosurgical procedures performed by the Division of Neurosurgery. The aim is to stimulate interest, share the knowledge, and provide an opportunity for undergraduate medical students to have a taste of Neurosurgery in Action. We will include general and basic procedures in the beginning,…
