ABSTRACT
A 14-year-old female, presenting sudden and progressive holocraneal headache along with incoercible vomiting arrived to emergency room. Acute confusional state and meningoencephalitis syndrome where identified. Brain computed tomography-scan with normal results was performed. Lumbar puncture with crystal-clear cerebrospinal fluid was obtained: low glucose, elevated proteins and cell-count of 15/mm. China-Ink and Criptococcus neoformans culture both positive. Viral, lupus-anticoagulant, and HIV tests negative. Fluconazole 200 mg/kg/day, amphotericin-B 0.7 mg/kg/day, dexamethasone 1 mg/kg/day were prescribed. 48-h later evolved to cerebral edema, multiple-organ-failure and death. Hereby we present a Cryptococcus spp. infection case report, addressing the public health challenge and vulnerability of immunocompromised patients in Mexico.
