An 8-year-old girl was admitted during the night in our emergency department for an acute episode of seizures. The patient underwent computed-tomography (CT) brain scan (Toshiba (R) Aquilion 64-TSX-101A/HC) and magnetic resonance imaging (MRI) brain scan (Philips (R) Achieva 1.5T). CT scan showed left frontal calcified nodules and calcified periventricular subependymal nodules. Subsequently, MRI evaluation revealed cortical and subcortical nodules that showed low signal with respect to the white matter on T1-weighted imaging sequences and high signal both in T2-weighted imaging sequences and in fluid-attenuated inversion recovery sequences. We also showed a herniation of cerebellar tonsils through the foramen magnum (Chiari malformation Type I [CMI]) with the associated hydrosyringomyelic cavity. Our report showed a rare association between tuberous sclerosis complex and CMI.

Abstract
An 8-year-old girl was admitted during the night in our emergency department for an acute episode of seizures. The patient underwent computed-tomography (CT) brain scan (Toshiba (R) Aquilion 64-TSX-101A/HC) and magnetic resonance imaging (MRI) brain scan (Philips (R) Achieva 1.5T). CT scan showed left frontal calcified nodules and calcified periventricular subependymal nodules. Subsequently, MRI evaluation revealed cortical and subcortical nodules that showed low signal with respect to the white matter on T1-weighted imaging sequences and high signal both in T2-weighted imaging sequences and in fluid-attenuated inversion recovery sequences. We also showed a herniation of cerebellar tonsils through the foramen magnum (Chiari malformation Type I [CMI]) with the associated hydrosyringomyelic cavity. Our report showed a rare association between tuberous sclerosis complex and CMI.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
