Table 5 Overview of how location of etiology (rows) is distributed between the groups of radiological morphology (columns)
From: Childhood hydrocephalus – is radiological morphology associated with etiology
Groups of radiological morphology | |||||||||
|---|---|---|---|---|---|---|---|---|---|
A1 – Symmetry in the AP and LR axes, with external hydrocephalus | A2 - Symmetry in the AP and LR axes without external hydrocephalus, moderate dilation | A3 – Predominant severe dilation, symmetry in the AP and LR axes | B1 – Predominant dilation of the occipital horns | B2 – Predominant dilation of the frontal horns | C – Predominant asymmetry in the LR axis | X – Not categorized | Total | ||
