An 11-yr-old child presented with acute mental status changes and spastic quadriplegia after orthotopic liver transplantation. Magnetic resonance (MR) imaging findings were consistent with central pontine and EPM. Initial immunosuppression included tacrolimus, mycophenolate mofetil, and corticosteroids. Given that neurotoxicity is a well-established side effect of CNI, the patient was converted to rapamycin and subsequently experienced significant neurologic recovery. The temporal resolution of the patient's symptoms suggests that prompt recognition of central pontine and EPM and conversion from tacrolimus to rapamycin during the early post-operative course may have therapeutic benefits for patients undergoing pediatric transplant with CNI-related neurotoxicity.
Congenital central nervous system (CNS) infections are a cause of significant morbidity and mortality. The recent Zika virus outbreak raised awareness of congenital CNS infections. Imaging can be effective in diagnosing the presence and severity of infection. In this paper we review the clinical presentations and imaging characteristics of several common and less common congenital CNS infections.
Optic nerve tortuosity at baseline is associated with OPG development among patients with NF-1, but does not predispose to aggressive OPG with associated vision loss. Neither nerve nor sheath thickening at baseline is associated with OPG development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
