Pyogenic brain abscess, ventriculitis and diffuse meningitis with fatal outcome in an adult: Radiologic–pathologic correlation☆,#

Rupture of brain abscesses with evolution into ventriculitis with meningitis may result in sudden and dramatic worsening of the clinical situation. We present a 57-year-old man with such an event and fatal outcome. Multiple imaging modalities including computed tomography and advanced magnetic resonance imaging were correlated with gross specimen and histologic images. The differential diagnosis of multiple lesions with ring enhancement and prominent perifocal edema includes mainly infectious and neoplastic processes, such as brain abscess, metastasis, and multicentric glioblastoma. Pyogenic ventriculitis is an uncommon manifestation of severe intracranial infection that might be clinically obscure. We discuss the characteristic magnetic resonance findings of brain abscess and its complications, including meningitis and ventriculitis with emphasis on the role of diffusion-weighted and fluid-attenuated inversion recovery imaging.

Early cognitive development in children born to women with epilepsy:A prospective report

Purpose: In this prospective study the early cognitive development of children born to women with epilepsy (n = 198) was assessed and compared to a group of children representative of the general population (n = 230). Methods: The children were assessed when younger than the age of 2 years using the Griffiths Mental Development Scales, either in their local participating hospital or in their home. The assessments were completed by an assessor who was blinded to whether the child’s mother had epilepsy and to antiepileptic drug type. Results: Children exposed to sodium valproate had a statistically significant increased risk of delayed early development in comparison to the control children. Linear regression analysis showed a statistically significant effect of sodium valproate exposure on the child’s overall developmental level that was not accounted for by confounding variables. Delayed early development is also noted for children within an ad hoc group of less commonly utilized antiepileptic drugs, although conclusions cannot be drawn due to the size of this group (n = 13). Children exposed to either carbamazepine or lamotrigine in utero did not differ significantly in their overall developmental ability. Differences noted in specific developmental areas for these two groups were not statistically significant after the control for confounders such as socioeconomic status and maternal IQ. Discussion: Women with epilepsy should be informed of the risks posed to their potential offspring prior to pregnancy to allow for informed decisions regarding treatment. Children exposed in utero to antiepileptic drugs should be monitored throughout childhood to allow for early intervention when necessary
