Brain Abscess Following Intracerebral Hemorrhage in a Patient With Pneumonia

Brain abscess is a rare but potentially lethal infection of brain parenchyma, requiring prompt surgical intervention and high-dose antibiotic therapy. Brain abscess is a known complication of surgically treated intracerebral hemorrhage (ICH), but it is exceptionally rare that it occurs at the same site of a nonoperated ICH. Such cases may result from hematogenous spread from distant foci (pneumonia, infectious endocarditis) or contiguous sites. Herein, the authors report a case of 75-year-old woman presenting with a brain abscess 6 weeks after a nonoperated ICH. As the patient suffered from pneumonia during the course of ICH, the authors suspected that the brain abscess might originate from the pneumonia via hematogenous spread. The awareness of brain abscess formation at the site of ICH is of great importance for early diagnosis and prompt treatment.
