A rare clinical report of giant hemangiopericytoma.

Authors show an example of a successful treatment of a patient with a giant intracranial hemangiopericytoma. Hemangiopericytoma are aggressive tumors with a high rate of recurrence and metastasis. Despite the malignant nature of these tumors often reach a large size with minor clinical signs.

[Cerebrospinal fluid sorption in the system of complex treatment of chronic cerebral ischemia].

The cerebrospinal fluid was investigated in 16 patients with chronic cerebral ischemia. Reactions of the local immune system of the liquor was shown to change by the autoimmune type. Medical efficiency of cerebrospinal fluid sorption was proved and it can be considered a method of detoxication aimed at breaking the pathogenetic chain: formation of abundance of the autoantibodies--increased amount of the circulating immunocomplexes--damage of the cell membranes--discharge of deep antigens--appearance of a new generation of autoantibodies.
