What is Intracranial Infection?

Urgent infection of the meninges might be bacterial or viral in origin. Tuberculosis and rarer pathogens may lead to meningitis as well, for instance, protozoa and fungi. A sterile meningitis can lead to leukaemic cell infiltration.

Purulent meningitis is quite common among preschool years and in childhood. About thirty-five per cent of childhood examples happens in the first, and eighty per cent before five years of age. One in five hundred children suffer from purulent meningitis from one month the age of ten years in the UK. It is necessary to make an early diagnosis as delay increases the danger of neurological complications, even death.

Those young infants have the tendency to appear with poor feeding, drowsiness, vomiting, and a fever. On this age, many group have a convulsion as the first feature of illness. Due to the hard of excluding meningitis on clinical grounds in this age group, an infant, who has a fever with convulsion almost invariably warrants a  lumbar puncture.

The reason why a child with an otitis media or other upper respiratory tract infection fails to respond to an antibiotic and gets increasingly drowsy is that the development of complicating meningitis .What is more, associated with an upper respiratory tract infection, pneumonia or cervical lymphadenitis, those children might indicate meningismus. In other word, in the absence of intracranial disease, they have the features of meningeal irritation.

Nevertheless, lumbar puncture is not without risk in the child with meningitis. As a fact, it is thought to be very risky in some instances. Further more, after blood cultures have been taken, treatment is began.
