Adenoid cystic carcinoma is rare, locally aggressive salivary gland tumor. It has indolent course, multiple local recurrences and delayed distant metastasis in lung, bone, liver and soft tissues which are detected up to a maximum of 5.5 years after local-regional resection of the primary tumor. Intracranial remote metastasis of ACCs is extremely rare, and very few cases have been reported in the literature. Here we report a rare case of intracranial remote metastasis of ACC of the parotid gland developed after 15 years of primary curative surgery, emphasizing long term follow up on these cases.
