Abstract
A constellation of plain film findings which can assist in the diagnosis of large intracranial arteriovenous malformations in the newborn is presented. Alone, none of these findings is specific but in combination they become highly suggestive of the diagnosis. They consist of: 1. cardiomegaly with right chamber preponderance and superior mediastinal widening, 2. retrosternal fullness and posterior displacement of the trachea, and 3. retropharyngeal soft tissue thickening.
