Intracranial Metastatic Adenoid Cystic Carcinoma: Report of Two Cases

ABSTRACT

The authors describe two cases of unusual intracranial metastatic adenoid cystic carcinomas. A 42-year-old woman had a right parietal epidural metastatic mass, presumed hematogenous, spread from a primary tumor in the parotid gland. In second case, a 32-year-old man had a intracranial metastatic adenoid cystic carcinoma mimicking calcified psammomatous meningioma on CT scans. We present the unusual cases with a review of relevant literature and a discussion of possible pathogenesis.
