Insights into the pathogenesis of cerebral lesions in incontinentia pigmenti.
We report the case of a neonate with incontinentia pigmenti and seizures on day 4 of life who underwent magnetic resonance imaging and angiography scanning at 8, 13, and 21 days of age. The serial magnetic resonance images demonstrated the evolution of acute microvascular hemorrhagic infarcts in the periventricular white matter in the first week of life. The associated magnetic resonance angiogram findings consisted of decreased branching and poor filling of intracerebral vessels. This report adds important insights into the nature and timing of cerebral lesions in incontinentia pigmenti.
