title: Factor XI deficiency-related spontaneous primary intraventricular hemorrhage.
abstract: Factor XI deficiency (plasma thromboplastin antecedent deficiency) is a rare autosomal-dominant disorder. Neurologic complications in factor XI deficiency are even rarer. We propose that the factor XI deficiency in our patient contributed to a primary intraventricular hemorrhage.
