Infectious and inflammatory diseases of the brain can be caused by bacteria, viruses, fungi and parasites. Among bacterial lesions, meningitis, abscess and empyema are distinguished.
The consequences of the inflammatory process can be the phenomena of brain tissue atrophy, bias toward the brain structures, displacement and expansion of the cerebral ventricles. Sometimes enlarged subarachnoid spaces (cystic arachnoiditis) of the deposit of calcareous salts in old foci of inflammation (especially in tuberculosis) are sometimes found on the tomograms.
With parasitic infections (the most frequent of them are cysticercosis, echinococcosis and toxoplasmosis) on CT and MRI reveal multiple cysts. Often in the affected areas visible lime blotches. The latter are often quite clearly identified on the survey images of the skull, which forces the physician to perform a full clinical and radiation examination.
Hypertensive syndrome
This is a syndrome of increased intracranial pressure. It develops at volume formations in the cranial cavity, especially often with tumors, and violation of the outflow of cerebrospinal fluid from the ventricles of the brain, i.e. With the so-called occlusive hydrocephalus. As is known, there are two types of hydrocephalus - open and closed. At the first there is no occlusion of the cerebrospinal fluidways and the hypertensive syndrome does not develop, therefore the radial manifestations of these two forms are different.
With the advent of CT and MRI, the diagnosis of hydrocephalus has become easier. Tomograms determine the position, shape, size of the ventricles and other liquor spaces. At the same time, pathological conditions are revealed, which are the cause of the development of hypertensive syndrome (malformations of the brain, tumors, etc.).
