Abstract

We report the case of an immunocompromised patient with previously unrecognized Mendelian susceptibility to mycobacterial disease due to interleukin-12Rβ1 deficit, who developed fatal disseminated Mycobacterium tilburgii infection. Mycobacterial invasion caused severe neurologic complications, including refractory status epilepticus, leading to death, despite therapies, including surgical interventions.
