(a) Magnetic resonance imaging of the brain T2 coronal section showing well-defined lobulated lesion, hyperintense signal changes in mid to left side of suprasellar region with minimal extensive involvement of the left cavernous sinus. (b and c) Postcontrast axial section and sagittal section, respectively, showing slight irregular lesion wall with postcontrast enhancement with no obvious internal enhancing lesion or septa. (d and e) SWI sequence revealed no calcification

Height) showing thin enhancing wall without internal enhancing lesion located in mid to left side of the suprasellar region extending into the sellar region. [Figure 1a-c] There was minimal extensive involvement of the left cavernous sinus, right deviation and compression of infundibulum, and slightly upward pushed optic chiasma. However, on SWI sequence, there is no calcification. [Figure 1d, e] With craniopharyngioma as one of the differential diagnosis, pituitary hormonal profile of the patient showed increased level of serum prolactin and insulin-like growth factor 1, decreased level of serum cortisol.

After visualizing the left optic nerve and opening the left optico-carotid cistern, to our surprise, whitish multiple cystic structure was seen which was removed from optico-carotid space and prechiasmatic space. [Figure 2] Borosilicate glass pipette was used for meticulous removal of cystic lesion.
