This paper reports a 70-year-old woman with primary intraocular lymphoma who experienced persistent vertigo, bilateral hearing loss, left hemiparesis and direction-changing positional nystagmus three months after irradiation. An MRI scan depicted a space-occupying lesion in the left middle cerebellar peduncle and cytologic study of the cerebrospinal fluid disclosed lymphoma cells. Therefore, when a lymphoma patient experiences persistent vertigo, hearing loss, and central type nystagmus, an MRI and cerebrospinal fluid cytologic examinations should be performed to exclude the possibility of CNS involvement.Apogeotrophic type of direction-changing positional nystagmus; Central nervous system lymphoma; Primary intraocular lymphoma; Vertigo[SDGs]SDG3carmustine; cytarabine; dexamethasone; etoposide; methotrexate; methylprednisolone; vincristine; aged; article; brain stem tumor; case report; central nervous system tumor; cerebrospinal fluid cytology; female; hearing loss; human; lymphoma; metastasis; nuclear magnetic resonance imaging; nystagmus; symptomatology; tumor localization; vertigojournal article2-s2.0-0036128145
