FIG 4. 51-year-old male patient with headache.
A and B, FLAIR image shows a large cyst with a scolex in the right Sylvian fissure and a cyst in the suprasellar cistern on the right, which are consistent with neurocysticerosis. The presence of an additional cyst in the perimesencephalic cisterns could not be ruled out due to prominence of these cisterns.
C and D, FLAIR after 100% O2 shows increased SI in the sulci and basal cisterns, confirming the absence of cysts in the perimesencephalic cisterns. In addition, there was improvement in the visualization of the cyst in the right suprasellar cistern and its relationship to the M1 segment of the ipsilateral middle cerebral artery.
