Papiloma coroideo atípico en paciente de la tercera edad: Revisión bibliográfica a propósito de un caso

Abstract

Introduction: Choroid plexus tumors are rare. They account for 0.3 to 0.6% of all brain tumors in adults and 10 to 20% in infants; in whom 70% of these have been registered and of which at least 50% occur in children under two years of age.
Objectives: This publication consists of describing a case of the third age with atypical papilloma of the fourth ventricle, the selected form of resolution and reviewing the bibliography on the subject.
Case presentation: 71-year-old male who consulted for gait instability and intermittent holocranial headache. On examination, he was disoriented, with memory disorders, magnetic gait, and urinary incontinence. Contrast-enhanced CT and subsequent MRI of the brain with gadolinium were performed, showing a 10 cc hypo-isointense occupying space lesion. Approx. occupying the 4th ventricle, with intense enhancement to contrast administration and ventriculomegaly associated with transependymal edema.
Intervention: Exeresis is performed, achieving complete resection and clinical improvement.
Discussion: Atypical choroid plexus papilloma (Grade II) is an intermediate entity that is fundamentally distinguished from grade I papilloma by its mitotic activity; 2 or more mitoses in 10 fields.
Conclusion: This report addresses a surgically challenging pathology, potentially curable and classically infantile, but which can also occur in the geriatric population.
