Background Acanthamoeba sp. are known to cause fatal granulomatous Acanthamoeba encephalitis (GAE) in immunocompromised patients.
Methods The case of a 17 year old immunocompetent patient with acute purulent meningoencephalitis is reported.
Results After substantial improvement of cerebrospinal fluid under conventional antimicrobial treatment the patient was suffering several relapses. The causative agent was identified as Acanthamoeba lenticulata T5 which entered the CNS through a bone dehiscence of ethmoidal cells. Due to severe vasospasm the patient developed multiple strokes, which led to marked neurologic sequels.
Conclusions This case report demonstrates successful treatment of usually lethal GAE in an immunocompetent patient with high dose meropenem, linezolid, moxifloxacin and fluconazole followed by a partially adapted antimicrobial combination therapy.
