title: Sarcoidosis of the cauda equina mimicking leptomeningeal malignancy.
abstract: Isolated neurosarcoidosis can present with a wide range of central nervous system manifestations. We present two cases of cauda equina sarcoidosis misdiagnosed initially as leptomeningeal malignancy, and review the literature. This unusual manifestation of neurosarcoidosis is typified by an indolent, chronic process with limited response to corticosteroid therapy.
