We appreciate the additional information provided by Hill and Silver and their interest in our study. Using a retrospective design, the authors studied the recurrence rate of intracerebral hemorrhage.1 They found multiple simultaneous lobar-type hemorrhages in 7 patients with no history of arterial hypertension. In 2 of them, biopsy results proved amyloid angiopathy. In contrast, all of our patients had uncontrolled hypertension and subcortical or cerebellar location.2 We agree that these results may be limited because of the design (ie, small number of cases, prevalence of risk factors, and ethnic differences).
