Web-like malformation of the carotid artery and multicystic encephalomalacia.
Multicystic encephalomalacia and hydranencephaly lie within a spectrum of brain lesions linked to ischemic cerebral damage. Causes include vascular malformation, thrombosis, embolism, infection, and toxins. We describe an infant with multicystic encephalomalacia associated with a peculiar web-like malformation of the right common carotid and left subclavian arteries. We postulate that this luminal bridging is a congenital malformation resulting from defective canalization of the medium-sized blood vessels but could represent organized and recanalized thrombi, the etiology of which remains unknown.
