Close
Large, well-defined, extra-axial, wedge-shaped, cystic lesion of CSF density noted in the left frontal region. The lesion is causing compression of:
- the ipsilateral basal ganglia,
- frontal horns of bilateral lateral ventricle,
- mild dilatation of occipital horn of right lateral ventricle,
- midline shifting of the ipsilateral lateral ventricle.
However, no communication to the ventricular system is noted. There is no cortical scalloping seen with surrounding compressed brain parenchyma.
