Endoscopic trans-nasal transphenoidal decompression of sellar supra-sellar cystic craniopharyngioma

Two patients with almost identical lesions on mri.

Very elegant minimally invasive surgery.
Problems: Some part of the capsule may be left behind although not readily apparant on post op scan. Planned for close follow up for recurrence. Gammaknife/ reexcision then?
both patients had transient diabetes insipidus.
surgeons: Roopesh, Prof S Gopalakrishnan [Otorhinolaryngology dept], Somnath.
