title: Brain abscess from a peritonsillar abscess in an immunocompetent child: a case report and review of the literature.
abstract: A brain abscess is uncommon but potentially lethal. Common predisposing risk factors include congenital cyanotic heart disease, immunocompromised status, and the presence of septic foci. We describe a left frontal brain abscess accompanied by fever, headache, and weight loss for a 3-month period. The presumptive source of the brain abscess involved a left peritonsillar abscess. To the best of our knowledge, one similar case was reported in the literature in 1929. The specific signs of peritonsillar abscess in our patient included trismus, decreased phonation, and a muffled voice. The peritonsillar abscess was not clinically diagnosed, but incidentally detected on lower axial sections of cranial magnetic resonance imaging. Fever and trismus improved after surgical drainage of the peritonsillar abscess. The cerebral abscess was conservatively treated with intravenous antibiotics. The patient developed hydrocephalus as a sequela to the involvement of the basal meninges.
