Abstract
Two cases of unilateral subependymal germinal matrix haemorrhage associated with homolateral periventricular haemorrhagic infarction (PVHI) are reported in two premature newborns. This association is rather rare. Indeed, PVHI occurs generally with large intraventricular haemorrhage. Diagnosis is made by brain imaging (ultrasound, MRI) scans and single photon emission computed tomography. PVHI is probably caused by obstruction of periventricular venous drainage by large intraventricular haemorrhage leading to a haemorrhagic venous infarction. From our cases, we conclude that extraventricular haemorrhage leading to a large subependymal haematoma can result in obstruction of periventricular venous drainage, subsequent PVHI and abnormal neuromotor development.
