Neoplasm of unspecified nature of brainh/o brain tumor; preop planning for biopsy There is redemonstration of a mass centered in the left thalamus measuring 46 x 33 mm axial dimensions. There is associated signal abnormality involving the right thalamus, the left caudate nucleus, the left lentiform nuclei and the midbrain. There is greater involvement of the left cerebral peduncle compared to the right cerebral peduncle. This appearance is stable when compared to the previous exam from 6/2/2015Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate minor opacities. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.There are defects present along the skin surface along the right occipital and right parietal scalp.Fiducial markers are in place.
1.A mass is centered in the left thalamus associated with signal changes in the left basal ganglia and infiltration into the right thalamus. It is stable compared to the prior exam. Examination was performed for the purpose of stereotactic surgical guidance2.There are defects present along the skin surface along the right occipital and right parietal scalp. Please correlate with physical findings on clinical exam
