masses and insufficiently expressed coagulation of the outflowing blood due to the presence of a low content of fibrinogen in it or an admixture of cerebrospinal noisy liquid.

In chronic pachymeningitis, fibrosis of the hard shell develops ki of the brain and spinal cord, it fuses with the surrounding fabrics. Propagation of the process along the hard shell spinal cord contributes to the formation of a muff-like thickening with subsequent compression of the roots of the spinal nerves and their atrophy.

Hemorrhagic internal and intradural pachymeningitis is varied. Small hemorrhages in the dura mater the shell does not give any symptoms. With extensive hemorrhageheadache that occurs in the acute period, gradually taking it is diffuse, accompanied by vomiting and sometimes loss of consciousness niya. There is often a decrease in memory, apathy, sometimes, on the contrary, psychomotor agitation. Focal neurological symptoms depend sit from the localization of hemorrhage. Weakly expressed meninges are revealed.

It sometimes notes an increase increased protein content, slight pleocytosis, mild xanthochromia. In a number cases of hemorrhagic cerebral pachymeningitis is complicated by edema lump of the brain.

Treatment in most cases is surgical. With external pus-

For pachymeningitis, large doses of antibiotics are administered simultaneously. With internal purulent cerebral pachymeningitis, treatment, as a rule, forcibly, conservative; it is aimed at the underlying disease and combines it is combined with anti-inflammatory and dehydration therapy. In the presence of subdural abscess requires surgery, as well as

with extradural abscess. The prognosis with timely treatment, as generally favorable.

3.5. Tumors of the meninges

The meninges can be affected by benign and malignant natural tumors. In the dura mater or its processes, less often in the soft shell, there are arachnoid endotheliomas (meningiowe), which grow towards the brain, pushing and squeezing it. Macropically, meningioma is usually a well-demarcated dense round knot of various sizes. Clinical course slow, the duration of the disease is often calculated by many for years. Symptoms vary; usually observed
