These findings suggested a cystic craniopharyngioma (Figure 1).
Postinjection Bremsstrahlung imaging by brain Single-Photon Emission Computed Tomography (SPECT). Brain SPECT coregistered with a computed tomography, showing a focal area of intense uptake in the suprasellar region, matching the shape of the cyst.

A brain Single-Photon Emission Computed Tomography (SPECT) was performed immediately after the injection showing adequate placement of the isotopes (Figure 2).
Follow-up image. Cerebral Magnetic Resonance Imaging enhanced with gadolinium contrast 22 months after intracavitary irradiation with radioisotope 32P.

The last MRI (Figure 3) was performed 21 months afterwards and showed a marked decrease of the signal intensity of the cyst content with evident size reduction.
