Abstract
In the setting of HIV, cerebral lesions are usually secondary to lymphoma and opportunistic infections; however, in patients with CD4 counts above 200 cells/uL, other pathologies such as pyogenic brain abscess could gain importance. The microbiology of pyogenic brain abscess has
and
as the leading etiologic pathogens in immunocompetent individuals.
is also recognized as a common cause of brain abscess in this patient population. In HIV-infected individuals, there have been sporadic reports of
infections but none of brain abscess. We describe the case of a 43-years-old HIV-infected patient with a CD4 count of 350 cells/uL that developed a
brain abscess presumably from hematogenous spread of an odontogenic source. Treatment with stereotactic needle aspiration in two opportunities and four weeks of intravenous antibiotics led to a complete resolution of this infection. This case highlights the importance of a multidisciplinary approach for an effective treatment of pyogenic brain abscess in HIV-1 patients.
