RESUMEN
Objetivo: estandarizar la metodología diagnóstica diferencial de lesiones pseudotumorales. Analizar a partir de este caso la aparición de esta entidad poco habitual en la población adulta. Material y métodos: se realiza historia epidemiológica de un paciente masculino de 51 años de edad que concurre a través de consultorios externos presentando inestabilidad en la marcha y diparesia braquial de 7 días de evolución. Como antecedentes refiere episodio febril de origen desconocido y resolución espontánea 20 días previos. Resultados: se realizaron estudios de tomografía axial computada y resonancia magnética nuclear de encéfalo evidenciando lesiones bilaterales. Se completa estudios con screening oncológico negativo. Líquido cefalorraquídeo: bandas oligoclonales negativas, proteinorraquia, PCR + para VEB. PESS, PEV, PEA: negativos. Se somete a tratamiento médico con metilprednisolona 1 gramo diario durante 3 días. Conclusiones: el ADEM (Encefalopatía Desmielinizante Aguda) es una entidad inflamatoria inmunomediada de diversas formas de presentación. Cumple un rol importante en el diagnóstico, la correlación de antecedentes epidemiológicos del paciente como así también la evolución progresiva del cuadro clínico y estudios complementarios.
ABSTRACT
Objective: To standardize the differential diagnosis method of pseudotumoral lesions. To analyze from this case the occurrence of this unusual condition in adults. Material and methods: An epidemilogical history is conducted in a 51 year old male patient who comes to the out-patient offices showing walking instability and brachial cliparesis during 7 days. The patient reports a febrile state with spontaneous resolution 20 days before the consultation as background. Results: A computerized axial tomography and an encephalic nuclear magnetic resonance were performed showing bilateral lesions. The studies were complete with an oncologic screening of negative results. Cephalorachidian liquid: negative oligocional bands, proteinorachia, detection of EBV (Epstein-Barr Birus) by PCR (Polymerase Chain Reaction). SEPs (Somatosensitive Evoked Potentials), VEP (Visual Evoked Potentials), PEA (Auditory Evoked Potentials): NEGATIVE. The patient receives medical treatment with 1 gram daily methylprednisolone for 3 days. Conclusions: ADEM (Acute Disseminated Encephalomyelitis) is an immune mediated inflammatory condition that can appear in several ways. The patient's epidemiological background correlation, as well as the progressive evolution of the medical condition and complementary analyses play an important role in diagnosis.
