The Teaching Point

Balamuthia mandrillaris has recently emerged as an increasing relevant pathogen capable of producing a highly lethal granulomatous amebic encephalitis in both immunocompromised as well as healthy host. The consistent pattern of poorly defined ring enhancement and adjacent leptomeningeal enhancement with focus of central hemorrhage on radiological imaging should be especially viewed with caution as this may suggest fulminant angioinvasive GAE, particularly in the setting of recent solid organ transplantation.

Abstract
We report the first identified transmission of Balamuthia mandrillaris through solid organ transplantation. Kidneys were transplanted from a donor with presumptive diagnosis of autoimmune encephalitis. Shortly after, the recipients developed neurologic symptoms. Magnetic Resonance Imaging of the brain from the donor and both kidney recipients demonstrated multiple ring enhancing lesions with surrounding edema and adjacent leptomeningeal extension. In addition most of the lesions demonstrated signal changes suggesting central hemorrhagic foci. Specimens were tested locally and at the Centers for Disease Control and Prevention. Histopathology revealed B. mandrillaris in either brain tissue and/or cerebral spinal fluid in the donor and recipients.
