Intraparenchymal brain hemorrhage and remote soft tissue arteriovenous malformation in a newborn infant.

Congenital arteriovenous malformations (AVMs) often present with congestive heart failure. Such pathologic vascular structures typically occur in cranial, hepatic, or pulmonary locations and are usually associated with overlying external visible, tactile, or audible abnormalities. These vascular anomalies may also be associated with such complications as thromboembolic events, coagulopathy, and localized hemorrhage. We present a newborn infant with an occult but hemodynamically significant parascapular AVM who presented with an intraparenchymal brain hemorrhage, which we suspect to be a remote complication of the AVM.
