A case of primary central nervous system lymphoma with dizziness and hearing impairment as the initial symptoms

Abstract

Primary central nervous system lymphoma (PCNSL) is a lymphoma that is confined to the brain and spinal cord. The clinical manifestations vary depending on the site of origin, but the main presenting complaint in most cases is loss of memory. In this study, we encountered a case of PCNSL in which the patient presented to the ENT department with the complaints of dizziness and hearing impairment, which led to the diagno-sis. At the first visit, there were no neurological findings other than dizziness and hearing impairment, but as the disease progressed, many neurological findings became evident. Since the symptoms of PCNSL progress rapidly, it is necessary to perform detailed examinations, such as imaging tests, at an early stage without overlooking the slightest signs.
