Craniopharyngioma · Approach and Extent of Resection

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Location/extent + hypothalamic involvement + cystic-solid
   Tumor location and extent? Hypothalamic involvement? Cystic or solid? (Perioperatively assess and replace the pituitary-adrenal/thyroid axes, watch for diabetes insipidus (DI) and water-sodium disturbance; vision and visual fields are key to monitor.)
   • Midline, intrasellar/suprasellar, subchiasmatic, reachable transsphenoidally → Midline accessible → endoscopic transsphenoidal
   • Large, lateral, retrochiasmatic, protruding into the third ventricle → Large/lateral/third ventricle → transcranial
   • Marked hypothalamic involvement (high morbidity risk with forced GTR) → Hypothalamic involvement → subtotal + radiotherapy
   • Predominantly cystic, tense cyst/recurrence unsuitable for re-craniotomy → Predominantly cystic → Ommaya/intracystic therapy
2. [End] Midline accessible → endoscopic transsphenoidal
   Midline, intrasellar/suprasellar, subchiasmatic → endoscopic transsphenoidal (extended endonasal) approach: decompress the visual pathway under direct vision, a chance to preserve the pituitary stalk, maximal resection within safe limits; emphasize skull base reconstruction and CSF leak repair.
3. [End] Large/lateral/third ventricle → transcranial
   Large/lateral/retrochiasmatic/protruding into the third ventricle → transcranial approach (pterional, interhemispheric trans-lamina terminalis, transcallosal, etc. by location) to address lateral and third-ventricle components; combined approaches if needed.
4. [End] Hypothalamic involvement → subtotal + radiotherapy
   Marked hypothalamic involvement → planned subtotal resection (relieve mass effect, protect the hypothalamus) + postoperative radiotherapy (conventional/proton): tumor control comparable to GTR but less hypothalamic obesity, endocrine and cognitive harm; do not sacrifice hypothalamic function to achieve GTR.
5. [End] Predominantly cystic → Ommaya/intracystic therapy
   Predominantly cystic/tense cyst/recurrence unsuitable for re-craniotomy → Ommaya reservoir drainage ± intracystic therapy (interferon etc.) to relieve mass effect, as adjunct/palliation; radiotherapy as needed thereafter.
