Pulmonary Arterial Hypertension as a Fatal Complication of Neurofibromatosis Type 1 in a Neonate: A Diagnostic Dilemma.

Neurofibromatosis type 1 (NF1), or von Recklinghausen disease, is a genetically transmitted autosomal dominant disease, with a prevalence of one per 4000 live births. Pulmonary arterial hypertension (PAH) is a rare but potentially life-threatening complication of NF1. There are no confirmatory data about the congenital association between PAH and NF1. However, in most cases, PAH is observed in late childhood or adulthood. Herein, we present a preterm baby with genetically confirmed NF1 who presented with PAH.
