We report a subependymoma of the fourth ventricle associated with narcolepsy. The patient was a 50-year-old woman with a long history of narcolepsy who died of colonic carcinoma with no cerebral metastasis. She was positive for HLA-DR2. At autopsy there was a tumour dorsal to the fourth ventricle which involved the midbrain tectum and rostral pons. Histologic examination of the tumour confirmed it to be a subependymoma.<\/jats:p><\/jats:sec><jats:sec
