Neuroimaging in inborn errors of immunity: More than infections

Neurological involvement in IEIs is not uncommon and may be radiologically detectable, making imaging an important ancillary tool in their evaluation. Systematic recognition of primary and secondary neuroimaging features by neuroradiologists can raise suspicion for an underlying IEI, prompting appropriate immunologic and genetic work-up. Earlier diagnosis is crucial to enable timely implementation of preventive or targeted therapies, with the potential to improve long-term outcomes.
