case_images: Head CT. Severe dilation of the ventricular system, involving the
  third ventricle and lateral ventricles with transependymal edema and a
  multicystic lesion located in the subarachnoid space at the level of the
  lateral surface of the left cerebellar hemisphere.

case_images: A head CT scan revealed ventricular dilation and the presence of a cerebellar cyst (Figure 1); the magnetic resonance imaging (MRI) of the brain showed a left cerebellar cyst along with severe dilation of the ventricular system compatible with hydrocephalus (Figure 2), so that a ventriculoperitoneal shunt was performed.

  contrast (right) images with a multicystic lesion located in the
  subarachnoid space at the level of the lateral surface of the left
  cerebellar hemisphere. Note the absence of a scolex and the "mass
  effect".

case_images: Hematoxylin-Eosin staining of a biopsy specimen from the cerebellar
  cyst: A) Upper left image. Outer edge of the cyst containing an intense
  inflammatory infiltrate. Larger image. Wall of a cysticercus cyst in
  small magnification (2.52 x); B) Wall of a cysticercus cyst with
  cuticular (1), cellular (2), and reticular (3) layer (12.6 x). The
  cuticular layer shows small, villous protrusions, the cellular layer is
  located just below the cuticular layer, and the reticular layer is the
  larger one, containing a loosely arranged matrix, and excretory
  canaliculi.

case_images: Due to the clinical deterioration of the patient and the lack of a clear diagnosis, a biopsy of the cyst was performed with evidence of a cysticercus cyst (Figure 3).
