It is true that cerebral biopsy has established a sure diagnosis in about 1/3 of cases, but it is also true that only 2 patients have had a benefit from that procedure, apart from the risks linked to the procedure. Cerebral biopsy remains a procedure to be used only in particular cases and with all possible precautions: it cannot certainly become a routine procedure. A little note: vasculitis, diagnosed in about half of the patients, has been confirmed in no cases by biopsy: a mistaken diagnosis? An overestimation of a little frequent disease?
