[Rendu-Osler-Weber disease with cerebral hemorrhage due to a capillary telangiectasia: a case report]

We encountered a case of acute cerebral hemorrhage secondary to capillary telangiectasia in a 10-year-old female. She was diagnosed as having Rendu-Osler-Weber disease (ROW). In this case, the cerebral hematoma did not result in neurologic damage and the final outcome was excellent. ROW is an autosomal dominant disorder characterized by the presence of vascular malformations of varying types in several tissues, including the brain, nasal mucosa, lungs, gastrointestinal tract, and liver. Neurological complications occur in 8 to 12 percent of patients with ROW. The pons is the most common site of capillary telangiectasia, but most of the malformations caused are clinically silent. Massive cerebral hematoma due to capillary telangiectasia is rare. Cerebral hematoma due to hypertension in a child is less than that found in an adult. So in a child it is important to investigate the origin of cerebral hematoma.
