Female, 38 years old, with cranial pharyngioma, receiving radiotherapy, evaluate cystic lesions. Again seen is a primarily cystic, rim-enhancing lesion centered in the suprasellar cistern and third ventricle. Since the prior examination, there has been a slight decrease in size of the inferior aspect of the cystic lesion now measuring approximately 34 mm in the AP dimension, previously 40 mm. More superiorly, the lesion projects through the left foramen of Monro and into the left frontal horn to a similar degree as seen on the prior examination. The left lateral ventricle remains dilated, similar to prior with evidence of transependymal CSF flow. Subfalcine herniation and a midline shift to the right of up to 14 mm are unchanged. Evidence of left frontal approach biopsies again seen.
1.Slight interval decrease in the size of the inferior aspect of the cystic craniopharyngioma. Elsewhere, the lesion is not significantly changed.2.The lesion continues to obstruct the left foramen of Monro with stable left lateral ventricular dilatation.
