CARDOZA OCHOA, David Ricardo et al. “Double Cortex” Sign Visualized in 18F-FDG PET / MRI Coregistration in a Patient with Band Subcortical Heterotopia. Rev. Fac. Med. (Méx.)

Subcortical band heterotopia (HSB) refers to the presence of smooth bilateral bands of gray matter located in the subcortical white matter. Clinical presentation is widely variable, the presentation includes intellectual disability, epileptic seizures and varied conduct disorders, making a complex diagnosis. We present a case of a 20-year-old male with a long history of treatment-refractory epilepsy referred to our center for a 18F-FDG (18F-fluorodeoxyglucose) PET/CT (Positron Emission Tomography/Computed Tomography), to search for the epileptogenic focus. Additionally, a registration was carried out with another magnetic resonance imaging study (MRI), where the sign of double cerebral cortex was documented by MRI and PET/CT, visualized as a hypermetabolic pattern in subcortical band heterotopia.

Keywords : 118F-FDG; PET; RM; heterotopia; neurology.
