Clozapine-induced myocarditis in an adolescent male with DiGeorge Syndrome.

DiGeorge Syndrome (22q11.2 deletion syndrome) is a chromosomal disorder associated with both congenital heart malformations and schizophrenia, which is often treatment-resistant and may warrant treatment with clozapine. Clozapine-induced myocarditis (CIM) is a rare complication of clozapine therapy, with a reported incidence ranging from 0.015% to 3%. Fulminant CIM has a nonspecific presentation in both adult and pediatric populations and a mortality rate approaching 50%. Few cases of pediatric CIM have been documented in the literature. This report highlights a case of CIM in an adolescent male with DiGeorge Syndrome whose clinical course was characterized by a subtle, nonspecific presentation and resolution with supportive care.
