Presentation
On and off episodes of confusion, vomiting and headache, since two weeks.
Patient Data
Small heterogeneous lesion measures about 1 x 1 cm, involving the left side of the corpus callosum splenium, it shows heterogeneous signal intensity, with complete T2 hypo-intense hemosiderin rim, and surrounded by avid blooming artefact on SWI (hemorrhage), without evidence of enhancement or restricted diffusion.
There is evidence of blood in the occipital horn of the lateral ventricle, third ventricle and fourth ventricle, associated with dilatation of lateral and third ventricles.
Minimal sub-ependymal edema is noted.
Case Discussion
Features are suggestive of a cavernous malformation of the corpus callosum with blood in the ventricles and hydrocephalus.
No evidence of feeding artery or draining vein to suggest arteriovenous malformation (AVM) or Developmental venous anomaly (DVA).
Unable to process the form. Check for errors and try again.
