MR of hydranencephaly.

چکیده
MR imaging (at 1 .5 T) was performed on a 6-week-old girl whose history included irritability, retarded motor development, macrocephaly, and recent onset of diabetes insipidus. T1-weighted (spinecho 600/20 [TRfTE]) and spin-density (1400/20) images in the sagittal and axial planes revealed a fluid-filled supratentorial space with persistence of the fal x and relative sparing of posterior fossa structures (Fig. 1 ).

In a review of more than 2000 MR images of the brain we identified 35 patients with absence of the septum pellucidum. These patients were divided into seven basic groups as follows: septooptic dysplasia; schizencephaly; holoprosencephaly; agenesis of the corpus callosum; chronic, severe hydrocephalus; basilar encephaloceles; and porencephaly/hydranencephaly. Absence of the septum pellucidum was...

Arachnoid collapse is a previously unreported complication of endoscopic choroid plexus coagulation (ECPC) treatment of hydranencephaly and is demonstrated in this case report. The variable anatomy found in hydranencephaly supports the use of ECPC as the preferred treatment option. However, the same anatomical anomalies predispose the procedure to this unique complication. A brief literature re...

Eighteen infants and children with typical congenital hydranencephaly were studied by pneumoen cephalography, water-soluble contrast ventriculography, and cisternography (radioisotope or metri zamide). Pneumoencephalography and ventriculography suggested that the aqueduct was obstructed or markedly stenotic in all cases. Cisternography demonstrated blocks at the aqueduct and at the level of the...
