MR imaging of Lhermitte-Duclos disease: a case report.

Since 1920, when Lhermitte and Duclos first described a tumorlike abnormality of the cerebellum, which has come to bear their name, there has been an increasing number of reports of this rare entity [1-10]. Most cases have not had radiographic correlation , but there are several reported cases in which CT was part of the pretreatment evaluation [2-7], and one case was demonstrated on low-field MR imaging [6, 7]. We report a biopsy proved case of Lhermitte-Duclos disease imaged by CT and high-field MR imaging.
