Presentación sincrónica de tumor epidermoides intracraneal y absceso cerebral. Reporte de un caso

Abstract

Introduction: A patient with intracranial extradural epidermoid tumor with synchronous presentation with brain abscess and no history of penetrating head trauma, has not been previously reported in the revision of the subject made by the authors. A case with these characteristics is presented and also considerations about diagnosis and treatment. Case report: A 48-yearold female patient, with a history of chronic headache and cranial palpable tumor in left frontal region. Humoral studies were normal. Cranial MRI showed two juxtaposed, extra and intraaxial ring images. At surgery an extradural pearly tumor without evidence of intradural tumor on inspection was found, biopsy showed an epidermoid tumor. Persistence of intraaxial ring lesion in left frontal lobe was showed in postoperative imaging controls. A second surgery discovered a subcortical brain abscess and radical resection was done. Patient outcome has been without sequelae after four months of follow-up. Conclusions: An uncommon case where reported with extradural left frontal epidermoid tumor and ipsilateral frontal brain abscess synchronously presented, neither continuity nor fistulous communication were demonstrated on neuroimaging or surgical exploration.
