RESUMO
Neurological symptoms in COVID-19 patients have attracted the interest of the scientific community, yet their mechanisms remain unknown. In some circumstances, the presence of neurological manifestations may result in an incidental diagnosis after a detailed investigation. In the present letter, we discuss a case published by Demir et al., in which the diagnosis of COVID-19 enabled the diagnosis of a rare neurological disorder, characterized by bilateral brain calcifications, commonly known by the eponym Fahr's syndrome. In addition, we report a case of primary brain calcifications unveiled by a suspected coronavirus infection.

Las calcificaciones cerebrales agrupan diversas entidades patológicas que frecuentemente han sido referidas como enfermedad de Fahr. Estas tienen una presentación clínica variada, desde el curso subclínico hasta manifestaciones motoras convulsivas e inclusive demenciales. Se presenta el caso de una mujer de 46 años con una crisis epiléptica convulsiva generalizada, asociada a calcificaciones difusas por hipoparatiroidismo postquirúrgico, en quien se inicia reposición de calcio, logrando resolución del cuadro convulsivo. Este reporte destaca el abordaje fisiopatológico de las calcificaciones cerebrales por hipoparatiroidismo, la importancia de una definición más general de cómo sería el síndrome de calcificación cerebral teniendo en cuenta las diferentes entidades patológicas conocidas asociadas con diferente espectro clínico y, por último, pone en evidencia la carencia de investigaciones sobre el tema.
Brain calcifications group diverse pathological entities that have often been referred to as Fahr disease. These have a clinical presentation which varies from subclinical course to several motor manifestations and dementia. We report the case of a 46 year old woman with generalized seizures associated with diffuse calcifications on postoperative hypoparathyroidism in whom calcium supplementation starts achieving resolution of the symptoms. This report highlights the pathophysiological approach by hypoparathyroidism brain calcifications, the importance of a general definition as in the brain calcification syndrome considering different known disease entities associated with different clinical spectrum and, finally, demonstrates the lack of research on the subject.
