title: Cholangiocarcinoma presenting as a cerebellar metastasis: case report and review of the literature.
abstract: Cholangiocarcinoma is an uncommon tumor that presents with hepatobiliary dysfunction. We report a patient with a chronic progressive organic mental syndrome, diffuse weakness, and gait disturbance who was discovered to have obstructive hydrocephalus due to a neoplasm. Pathologic examination revealed primary cholangiocarcinoma metastatic to the cerebellum. This tumor has not been previously reported to present with neurologic involvement.
