title: Cerebral vasculopathy in divers.
abstract: Brains from 12 amateur and 13 professional divers, all but one of whom died accidentally, were examined neuropathologically. Grossly distended, empty vessels (presumably caused by gas bubbles) were found in the brains of 15 out of 22 divers who died from diving accidents. Perivascular lacuna formation was found in cerebral and/or cerebellar white matter in three amateurs and in five professionals. In addition to lacuna formation, hyalinization of vessel walls was present in the brains of three amateurs and five professionals. Necrotic foci in grey matter occurred in seven cases and perivascular vacuolation of white matter occurred in seven cases. The vascular changes probably arose from intravascular gas bubble formation. In one professional diver, there was also unilateral necrosis of the head of the caudate nucleus.
