“…[2,9] An alternate hypothesis is that ceftriaxone causes the release of inflammatory cytokines like tumor necrosis factor-alpha which triggers neurotoxicity. [14] Renal impairment [1,3,5,7,9,10,11,13,15] and old age [1,3,5,7,9,10,13,15] are the main predisposing factors observed in most patients diagnosed with CIE in the literature. Hepatic dysfunction, [5] impaired biliary excretion, [3] administration of high-dose ceftriaxone, [8] and preexisting neurological conditions [1,12] are the other risk factors associated with CIE. Cerebrovascular disease, [10,14] meningitis, [8] and cerebral contusion [15] are the neurological conditions that have been reported to predispose to CIE. e risk factors in the case we present are old age and the presence of a multicentric glioma.…”
