The cavernous angioma, although a common cause of non-hypertensive intracerebral hemorrhage, is angiographically silent. No example of the angiographic visualization of an intracranial cavernoma has been reported to date. Telangiectases rarely produce intracerebral hemorrhage but may be observed in angiography and may be associated with cavernous angiomas. A case with telangiectases, a cavernous angioma and hematoma of the brainstem, and a unique angiographic picture is presented with a review of the clinical, angiographic and pathological features of the uncommon vascular malformations. © 1974 Springer-Verlag.
