Craniopharyngioma with extension into the cerebellopontine angle. Case report

A rare case of craniopharyngioma which extended from the suprasellar region into the cerebellopontine angle (CP angle) is reported. This patient, a 18-year-old man who underwent two surgeries for suprasellar craniopharyngioma did not show recurrence during interval studies. However, nine years after the second surgery CT scan and MRI indicated a left CP angle mass when he was submitted to suboccipital craniectomy and tumor resection. He had been on human growth hormone (hGH) regimen for his pituitary dwarfism before tumor recurrence. The authors speculate retrospectively that the tumor growth in the left CP-angle was correlated with hGH therapy in this particular case.
