OBJECTIVE: The aim of this report is to describe 3 cases of salivary gland tumors with intracranial extension associated to an extracerebral mass lesion, and to discuss the frequence, pathology and treatment of these very rare localizations. CLINICAL MATERIAL: The 3 patients were 1 woman and 2 men, aged 44, 53 and 74 years, respectively. The primary tumors were an adenocarcinoma and a malignant oncocytoma of the parotid gland and an adenoid cystic carcinoma of the submandibular gland. The location of the intradural extra-axial tumor was the middle fossa and temporal region in 2 cases and the cerebellopontine angle in 1. Surgical treatment consisted in the seemingly complete removal of 2 tumors with middle fossa localization and partial removal of the cerebellopontine angle lesion. Radiotherapy was administered in all 3 cases and chemotherapy in 2. RESULTS: 1 patient is alive and free of recurrence 32 months after removal of the intracranial tumor; 2 other patients died 28 months and 12 months postoperatively. CONCLUSIONS: The intracranial extension of salivary gland tumors is a very rare event. An aggressive surgical resection followed by radiotherapy is justified in cases with significant intracranial mass lesions and scarce bone and dural involvement.
