Echography on day 3 showing a high echoic lesion in the cerebellar hemisphere (a, black asterisks). Sagittal (b) and coronal (c) spoiled gradient recalled echo (SPGR) imaging at 10 months old showing a nonrecognizable bilateral cerebellar hemisphere and hypoplastic cerebellar vermis and brainstem. Axial T2 star-weighted angiography (SWAN) showed hemosiderin deposits enveloping the cyst wall (d, white arrow) at presurgery. Midsagittal fast imaging employing steady-state acquisition (FIESTA) did not identify the cyst wall before surgery (e) but detected it after surgery (f, black arrow).

Postsurgical FIESTA images detected the cyst wall segment (Figure 1()).
A histological examination of the perforated cyst segment showed collagen fibers (asterisk), spindle cells, and hemosiderin deposits (white arrows) (hematoxylin and eosin staining, bar: 20 microm). A section of the cyst wall was fixed with formalin and embedded in paraffin.
