Resumen

Los xantogranulomas del ventrículo lateral son lesiones diagnosticadas infrecuentemente en la práctica clínica, ya que en la mayoría de los casos se comportan como masas asintomáticas que no provocan síntomas irritativos ni deficitarios. Se presenta el caso de una paciente de 30 años que debutó clínicamente con síntomas de hipertensión intracraneal y trastornos del campo visual, y que en el estudio de Resonancia Magnética (RM) presentaba una lesión temporal derecha intra y paraventricular isointensa en TI, con disminución de la intensidad de señal en T2 y con marcada captación de gadolinio en las imágenes potenciadas en TI. Fue intervenida mediante abordaje transtemporal con resección completa, siendo el diagnóstico histopatológico compatible con xantogranuloma. Se revisa la literatura y se discuten los hallazgos radiológicos.

Summary

Xanthogranulomas of the choroid plexus in the lateral ventricle are usually asymptomatic lesions found incidentally at autopsy. Symptomatic cases are rare. We present the case of a 30-year-old woman with a xanthogranuloma of the right lateral ventricle who showed intracranial hypertension and visual disturbance. Plain Tl-weighted magnetic resonance images disclosed a isointense right temporal lesion in the ventricular horn which showed decreased signal intensity on T2-weigted images and massive enhancement on Tl-weighted images after gadolinium injection. She was operated on through a right temporal craniotomy with total excision. We review the literature and discuss radiological findings on MRI.
