The sketch depicts clear criteria for (a') physiologic variants (1 = sharp lateral angle, 2 = concave bottom, 3 = smooth inner lining, and 4 = regular echogenicity of the parenchyma in this case) and (b') pathologic variants (1 = blunt/obtuse lateral angle, 2 = convexly shaped bottom, 3 = irregular inner lining, and 4 = asymmetry, atrophy, and porencephalic cysts as additional findings in this case) of mild enlargements of the lateral ventricle (modified illustration, [9]).

The cyst of DWM rarely extends posteriorly to almost completely fill the entire posterior fossa, which mimics primary cerebellar agenesis [4], a cerebellar porencephalic cyst [5], and an arachnoid cyst [6] due to the lack of clarity of the thin cystic wall; however, an accurate differential diagnosis is critical for selecting an appropriate surgical intervention.
The anatomical recognition of this variant becomes important for the occurrence of saccular aneurysms, relatively common (13-71%), associated malformations (dysgenesis of the corpus callosum, lobar holoprosencephaly, septooptic dysplasia, porencephalic cysts, and arteriovenous malformations), and presence of bifrontal infarctions in case of occlusion [1].
