First low : MRI showing an ill-defined, multicystic cerebellar mass with hyposignal on
T1-weighted images (left), hypersignal on T2-weighted images (middle), and rim
enhancement after gadolinium injection (right). Second low : Intraoperative views
showing a cystic mass in the cerebellar hemisphere (left) and a white cystic content,
grasped with forceps (right). Third low : Photograph of the specimen showing dense
collagen capsules with multiple cystic cavities and yellow cysts (upper) and photomicrograph
of cyst wall of cysticercus cellusosae showing a wavy, eosinophilic lamina
with hair-like protrusions (haematoxylin and eosin, original magnification, x40) (lower)
(left). Postoperative-8-month T1-weighted axial postcontrast MRI scan showing no
residual cyst with cerebellar surgical defect (right).
