Sella turcica is expanded and depth. Pneumatization of basic sinus is not damaged. Its determined the volume formation in the sellar field, its size 29 x 27 x 21 mm with supra and infrasellum proliferation, as well as the front, with rough and hilly contours. This formation accumulates contrast agent intensively and unevenly. It seems that formation assumes chiasm, which is deformed and increased in volume, heterogeneous. Infundibulum, hiazmo-sellar tank isn’t differentiated. The formation extends to the bottom of the III ventricle. There is swelling and reactive changes along the optic tracts symmetrically of both sides without pathological accumulation of contrast. The formation is adjacent to the both internal carotid arteries.
There are no changes of MR signal in gray and white matter in the basal ganglia, capsula interna corpus callosum. The are no focal changes of MR signal in brainstem and cerebellum. Median brain structures are not displaced.
Brain ventricles are not expanded, their shape is not changed. Lateral ventricles are symmetrical.
The subarachnoid space of the cerebral hemispheres and the cerebellum are not extended. Additional formations in the cerebellopontine angle are not identified. Inner ear canals are not expanded. Craniovertebral transition is without features.Paranasal sinuses and mastoid cells of temporal bones are developed properly, their pneumatization is not damaged. Orbits and retrobulbar space are normal, optic nerves are symmetrical, without features.
CONCLUSION: Volumetric formation of sellar region should be differentiated between macroadenoma and chiasm glioma with the spread on optic tracts.
