My wife did a CT scan today and they reported "mild low attenuation rounded prominence seen at the inferior margin of the splenium of the corpus callosum raising the possibility of a cyst measuring approximately 11 mm. No other focal intra or extra-axial lesions are seen. No odemia or haemorrhage is evident".
What does this mean? I searched the internet, there are plenty of reference to arachnoid cyst, colloid cyst, but little about cysts in the splenium of the corpus callosum? Is this treatable?
Conclusion was "mild lucent prominence of the splenium of the corpus callosum. further assessment with MRI was recommended.
What sort of treatment is available for pineal cysts?
If it's truly benign, what is the risk of not treating/removing it?
