Sellar chondroma in a case of Ollier's disease

Abstract

Chondromas are rare intracranial tumours. Sometimes they occur as a manifestation of a 'generalised chondromatosis'. The authors present a case of sellar chondroma in a patient with Ollier's disease. The tumour showed a mainly suprasellar extension resulting in a chiasmatic syndrome. The pathogenesis of intracranial chondromas, their clinical features, and CT- and MRI-findings are discussed.
