Incontinentia pigmenti is an X-linked dominant disorder resulting from a mutation of IKBKG. This disorder has a classic dermatologic presentation, but neurologic involvement, with seizures and cortical infarction, can arise shortly after birth. There are no specific therapies available for the manifestations of incontinentia pigmenti. Here, we describe the clinical, electrographic, and neuroradiologic effect of systemic glucocorticoid therapy in a neonate with incontinentia pigmenti manifesting an epileptic encephalopathy. Treatment with dexamethasone led to a dramatic reduction in seizure activity and improvement in bullous lesions. A novel mutation in IKBKG is also reported.

Incontinentia pigmenti (IP) is a rare X-linked multisystem disease caused because of mutation in the IKBKG (inhibitor of kappa-B kinase gamma, previously NEMO) gene. Involvement of central nervous system is seen in approximately one-third of these patients. Ischemic strokes, symptomatic seizures, and encephalopathy can be seen during neonatal or early infancy age group. Typically, early bilateral brain involvement is seen with periventricular white matter injury, hemorrhagic infarction, and multifocal cortical injury. We reported a patient who did not have early encephalopathic presentation, but presented with right hemiparesis and intellectual impairment. Magnetic resonance imaging of the brain revealed extensive left cerebral white matter volume loss and encephalomalacia with Wallerian degeneration of the left cortical spinal tract. This case highlights a rare presentation of unilateral cerebral atrophy with no definite episode of acute encephalopathy during infancy to suggest pure intrauterine injury. Microvascular occlusion, inflammatory cerebral vasculopathy, and recurrent silent strokes possibly produced this extensive neurologic manifestation antenatally. We also reviewed the complex pathogenic mechanisms involved in IP.
