Case in brief
A patient with rapidly progressive meningoencephalitis due to hypervirulent Klebsiella pneumoniae developed cerebral infarction and subsequent brain abscess formation during treatment. Initial MRI showed infarction linked to vasospasm, and follow-up imaging revealed abscess development within the infarcted area. Despite prolonged antimicrobial therapy, the patient experienced neurological impairment, although imaging showed significant resolution of the abscess by day 72.
What made this case unusual
The case is notable for the development of a brain abscess from a cerebral infarction during treatment for hvKp meningoencephalitis, without a typical remote infection focus.
Diagnostic / clinical pearl
Clinicians should be aware that severe hvKp meningoencephalitis can lead to complications such as cerebral vasospasm and brain abscess, necessitating careful monitoring through serial neuroimaging.
Why it matters
This case underscores the importance of recognizing potential complications in patients with hvKp infections, which may not present with typical infection foci, highlighting the need for vigilant imaging follow-up.
