Diffusion Tensor MR Imaging Tractography of the Pyramidal Tracts and Corpus Callosum in Children with Right-Sided Congenital Hemiparesis. A Case Report.

This study used diffusion tensor tractography to evaluate the diffusion parameters of the corpsus callosum and asymmetry in the diffusion parameters of the corticospinal tracts in children with congenital hemiparesis. Precision moving critically correlates with the integrity of the pyramidal tracts as evidenced in congenital hemiparesis by the correlation found between corticospinal lesions and motor deficits. Therefore we hypothesize that diffusion parameters correlate with the severity of hemiparesis measured using the Bayley Scales of Infant Development.

Pseudotumoural Hemicerebellitis: Conventional MR Imaging and MR Spectroscopy Evolution. A Case Report.

Acute cerebellitis is an inflammatory process commonly involving both cerebellar hemispheres. Bilateral cerebellar hemispheres involvement is the most common finding. It typically occurs as a primary infectious, post-infectious or post-vaccination disorder, but is also a disease entity with heterogeneous pathogenesis including paraneoplasia. Acute cerebellitis is usually a benign, self-limiting and rarely fatal disease. Typically, cerebellar atrophy is a late consequence of the syndrome. We describe the radiological features of a case of pseudotumoural hemicerebellitis with emphasis on MRI and spectroscopy findings as non-invasive diagnostic tools to avoid unnecessary surgical procedures.

Neonatal seizures in preterm infants: clinical outcome and relationship with subsequent epilepsy.

OBJECTIVE: Neonatal seizures are considered an acute manifestation of disturbance of the neonatal brain. Some of them can be considered as neonatal epilepsy. Our goal was to evaluate perinatal risk factors, electroencephalogram (EEG) findings and ictal semeiological characteristics of our newborns with neonatal seizures in order to identify which clinical variables were the most early predictive factors of poor neurodevelopmental outcome and of epilepsy. METHODS: Among all preterm infants consecutively admitted to the neonatal intensive care unit (NICU) of the University Hospital of Parma in the period between January 1999 and June 2003, 28 preterm infants with gestational age
