Background:
Incontinentia pigmenti is a rare X-linked neurocutaneous disorder that can present in the neonatal period with seizures and encephalopathy. Brain magnetic resonance imaging and magnetic resonance angiography may reveal cerebral infarction and arteriopathy.
Patient Description:
We describe a neonate with the typical rash of incontinentia pigmenti along with seizures and brain magnetic resonance imaging abnormalities.
Results:
Brain magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance spectroscopy at age one week revealed chronic and acute brain injury, arteriopathy of the small and medium-sized cerebral vessels, and elevation of a lactate metabolite peak. By age six months, her magnetic resonance angiogram had normalized. At age 2.5 years, she has well-controlled complex partial seizures, global developmental delay, and residual hemiplegia.
Conclusion:
Despite extensive cerebral arteriopathy in association with incontinentia pigmenti, this girl had a relatively stable early clinical course, steady developmental progress over time, and seizures that have been well controlled. Later brain imaging revealed resolution of the arteriopathy.
