Thanks for writing to us.
In all probability the vomiting
are as a result of raised intracranial tension(ICT) due to SOL( Space occupying lesion ) as revealed by MRI
as you have mentioned above. In general the raised ICT leads to loss of vision due to pressure effect on Optic Nerve
Considering the age factor and the location of lesion near to Vital Centres controlling Respiration and Circulation the NeuroSurgeons may not suggest Neuro Surgical intervention to remove the SOL.
Definitely a Palliative Surgical Procedure such as Right Ventriculo Peritoneal Shunting(Presuming the patient to be right handed) to preserve her Vision for lifetime can be requested by you.
Kindly go ahead and consult a Neurosurgeon at the earliest.
