Fetal cerebral ventriculomegaly: misidentification of the true medial boundary of the ventricle at US.

abstract：:The specificity of the intraarticular facet block as a diagnostic test for facet joint disease is currently unknown. Capsular rupture with epidural and periarticular diffusion is probably responsible for many false positive findings. We found a comparatively low success rate of the procedure in 25 patients in whom max...
