We reviewed the clinical and radiological features of ten patients with small arteriovenous malformations that caused intracerebral hematomas.In six patients,angiography showed a small nidus(less than 1 cm in diameter) with a shunt at the site of the hematoma,and in four only an early-filling vein was evident.Six patients had only delayed angiography(4 weeks or more after the ictus).In three,angiography within 2 days of the ictus failed to reveal the cause of the bleed,but repeat angiography showed an early- filling vein in two,and a nidus with shunting in one.In only one patient did early angiography reveal the malformation.MRI was obtained in eight patients,and in two prominent vessels were evident in the wall of the hematoma cavity.In investigation of an unexplained intracerebral hematoma, MRI may be useful to exclude a neoplasm or cavernoma,although the latter may not be evident in the presence of a recent hematoma.We suggest early MRI and angiography for investigation of an unexplained,nonhypertensive infracerebral bleed,with follow-up MRI and delayed angiography if the initial studies fail to reveal the cause. |
