Overview

Case report demonstrates successful multimodal resection of a giant skull base adenoid cystic carcinoma in an older adult, highlighting diagnostic challenges when tumors mimic glomus jugulare.

Key Points

  • To describe the clinical presentation, radiological evaluation, and successful multimodal surgical management of a rare giant posterior fossa adenoid cystic carcinoma mimicking a glomus jugulare tumor.
  • Clinical, MRI, and digital subtraction angiography assessment in a 60-year-old female presenting with lower cranial nerve palsies, unilateral hearing loss, and postauricular swelling.
  • Treatment protocol consisting of percutaneous embolization, external carotid ligation, surgical resection of the skull base mass, and adjuvant radiotherapy.
  • Histopathological analysis confirmed mixed adenoid cystic carcinoma despite radiographic features strongly suggesting a vascular glomus jugulare or sarcoma.
  • The postoperative course was uneventful, with no tumor recurrence or distant metastasis documented at 1-year follow-up.
