Vascular lesions in neurofibromatosis 1 (NF1) are infrequently recognised a
s manifestations of the disease, yet they can produce serious complications
, Most individuals with NF1 vasculopathy are asymptomatic, which may contri
bute to underestimation of its frequency. A recent study indicates that vas
cular changes in individuals with NF1 contribute to mortality at younger ag
es, We report the sudden death of a young man with NF1. On autopsy examinat
ion there was evidence of an intramyocardial vasculopathy characteristic of
the vascular pathology previously described in NF1, Other cardiac findings
included non-specific cardiomyopathic changes, myocardial fibrosis, and a
"floppy" mitral valve, (C) 2001 Wiley-Liss, Inc.
