Evaluate tumor size and ventricular size: optic glioma with hyponatremia. There has been interval increase in size of the lobular mass centered in the suprasellar cistern, now measuring 6.6 x 5.1 cm, previously 5.1 x 3.8 cm. There is also new susceptibility abnormality in the center of the lesion suggestive of hemorrhage. There is increased mass effect on the adjacent bifrontal and bitemporal lobes, as well as left cerebral peduncles, brainstem, and pituitary stalk. The mass encases and displaces portions of the bilateral internal carotid, middle cerebral, and anterior cerebral arteries. There is new encephalomalacia in the anterolateral right frontal lobe, which may be related to right frontal craniotomy for tumor biopsy. There is no evidence of acute infarction. There is bilateral tympanomastoid fluid.
Interval increase in size of the bulky suprasellar region low-grade astrocytoma with areas of intratumor hemorrhage. In addition, the lateral ventricles are now slightly dilatated due to mass effect upon the third ventricle.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
