Presentation
Headaches, periodic vomiting, learning difficulties. Deep brain tumor suspected on CT.
Patient Data
Left midbrain multilocular lesions that are isointense relative to CSF located at the cerebral peduncle and ventromedial thalamus without perifocal edema.
Mass effect to cisterna interpeduncularis and partially to end part of the 3th ventricle floor.
Minimal triventricular hydrocephalus, aqueduct of Sylvius slight displacement, tiny flow void artefact still present, seen on T2 axial images
The remainder of the brain appears normal.
Case Discussion
Specific findings of dilated perivascular spaces were revealed that excluded presence of tumor. It is uncertain why mild hydrocephalus exists, as CSF motion through aqueduct is present, on the other hand, there is evidence of 3th ventriclular narrowing and slight displacement of the aqueduct.
