Nontraumatic cerebral hemorrhage in the young: A study of 107 cases.

Background: Reports on intracerebral hemorrhage (ICH) in the young are rare, and information on the cause and prognosis of ICH in this age-group is sparse. Methods: All cases of ICH admitted to three major hospitals in Saudi Arabia over a 15-year period were retrospectively reviewed. Patients aged between 6 months and 45 years at stroke onset were studied. Pooling of our data with those published from other centers was used for final analysis. Results: One hundred seven cases (69 male, 38 female), including 12 children younger than 10, were analyzed. The causes of hemorrhage were as follows: arteriovenous malformations (AVMs), 23%; systemic hypertension, 20%; blood dyscrasias, 16%; berry aneurysms, 8%; other causes, 7%. No cause was found in 26%. Sixty-two percent of the ICHs were lobar and 3% multiple. Early death rate was high (27%). Twelve percent of the patients were lost to follow-up, and only 26% returned to a state of complete autonomy. Conclusion: The pooling of the causative data from our cases and the 253 others reported in the literature showed that even before 45 years of age systemic hypertension is the leading cause of ICH. It accounts for approximately 30% of the cases, with AVMs (20%) being next. The pooled overall early mortality rate is approximately 20%, and only one third of the patients return to independent living.
