UNLABELLED: A number of frequently unrecognised vascular manifestations have been described in patients with neurofibromatosis type 1 (NF1), including involvement of the great vessels, cerebral, visceral and renal arteries. Rarely, changes in the coronary arteries have been reported in adults with NF1. We report on a 16-year-old boy affected by NF1 with dysmorphic features and three aneurysms in the mid-portion of the left descending coronary artery disclosed by chance during investigation for a malignant peripheral nerve sheath tumour. Molecular analysis detected a gross de novo deletion in the NF1 gene. The boy had had no previous cardiac symptoms but died suddenly after developing signs and symptoms suggestive of myocardial infarction. CONCLUSION: To the best of our knowledge, this represents the first report of multiple lesions in the coronary arteries in a child affected by neurofibromatosis type 1 with a known deletion of the neurofibromatosis type 1 gene.
