Spontaneous Escherichia Coli Meningitis in an Adult

Escherichia coli meningitis has been reported rarely in adult patients. Moreover, it is very rare in an adult patient without diabetes mellitus or neurosurgical shunts. Even with treatment, it carries a high mortality ranging from 27% to 90%, and mortality without treatment is 100% [1-3].
We describe a rare case of an adult patient, without known predisposing factors such as diabetes mellitus or neurosurgical shunts, who presented with E. coli meningitis.
