Abstract
Description
El absceso encefálico es una infección focal localizada que puede afectar cualquier parte del sistema nervioso central, se caracteriza histopatológicamente por presentar un centro necrótico y un área perilesional de infiltrado inflamatorio mixto de linfocitos y polimorfonucleares en su etapa tardía. Entre los múltiples mecanismos etiopatogénicos se consideran como más importantes la diseminación por continuidad, por vía hematógena y la inoculación directa por trauma o por procedimientos quirúrgicos. Su sintomatología es inespecífica y depende de la localización, tamaño, número de lesiones, relación entre la virulencia del germen y el estado inmunológico del paciente, edema y grado de hipertensión asociado en dicha patología. El diagnóstico de absceso encefálico que se realiza mediante imágenes radiológicas como la tomografía axial computarizada o la resonancia magnética no resulta fácil debido a que puede confundirse con cualquier otra lesión ocupante de espacio, como por ejemplo un tumor cerebral. Se presenta un caso de absceso encefálico en un paciente masculino adulto mayor en el Hospital Universitario de Santander, Bucaramanga y se realiza correlación entre las manifestaciones clínicas y los hallazgos patológicos y radiológicos.

Brain abscess is a localized focal infection that can affect any part of the central nervous system, is characterized histopathologically by presenting a necrotic center and an area of perilesional inflammatory infiltrate of lymphocytes and polymorphonuclear late stage. Among the multiple pathogenetic mechanisms are considered most important for continuity spread by hematogenous and direct inoculation by trauma or surgical procedures. Its symptoms are nonspecific and depends on the location, size, number of lesions, relation between the virulence of the organism and the patient’s immune status, edema and hypertension associated degree in this pathology. The diagnosis of brain abscess is performed by radiological imaging such as computerized tomography scan or magnetic resonance imaging is not easy because it can be confused with any other space-occupying lesion such as a brain tumor. We report a case of brain abscess in an elderly male patient at the Hospital Universitario de Santander, Bucaramanga and performs correlation between the clinical and pathological and radiological findings.
