Craniopharyngioma, status post resection. Abnormal involuntary movements. Previously seen heterogeneous, enhancing, cystic and solid lesion centered on the suprasellar cistern demonstrates further slight decrease in size, currently measuring approximately 3.7 x 3.5 cm in the AP and transverse dimensions, previously 3.9 x 3.7 cm in the axial plane. Craniocaudally, the lesion measures 3.2 cm, previously 3.3 cm. Slight decrease in cystic components involving the superior aspect of the mass is noted. Mass effect involving the sella and suprasellar cistern including the optic apparatus, proximal circle of Willis, as well as the cerebral peduncles is similar to prior. Splaying of the interpeduncular cistern is also similar to prior. Mild prominence of the lateral ventricles is not significantly changed and likely related to mass effect on the foramen of Monro. No additional parenchymal lesions are seen. Diffusion and susceptibility weighted sequences are significantly degraded related to artifact, presumably from dental hardware. Sequelae of prior right frontal craniotomy are noted.
