Clinico-anatomical characteristics of 9 intracranial cavernous haemangiomas (CH) are given, 7 of them being found in the brain and 2 in the arachnoid membrane. The average age of patients with clinical manifestations of CH was 23.5 years. The emphasis is made on the appearance of the first CH symptoms in the females during the gestation, delivery or on the oestrogen treatment. The blood supply of CH is shown to be brought about from the small vessels on their periphery. The role of concomitant intracerebral cysts as an additional symptom is underlined. 6 clinical variants and 2 histologic types (typical and atypical) are distinguished. The suggestion about general embryogenetic roots of all intracranial angiomatous vascular malformations is put forward. CH, in spite of difficulties in their clinical diagnosis, are, as distinct from other vascular malformations, favourable object for the radical surgical treatment.
