title: A space-occupying lesion of the skull base, masked by nasopharyngeal lymphatic tissue hypertrophy and causing cranial nerve dysfunction in an HIV-infected patient.
abstract: Patients infected with HIV are at increased risk of developing lymphoma. The lymphomas often involve extranodal sites and +/-90% are of B-cell phenotype. We describe an HIV-infected patient with unilateral multiple cranial nerve dysfunction, most likely as a result of a nasopharyngeal B-cell non-Hodgkin's lymphoma in which early histologic confirmation of the diagnosis was delayed by the simultaneous presence of nasopharyngeal lymphatic tissue hypertrophy. It is of practical importance to recognize non-Hodgkin's lymphoma as a cause of cranial nerve dysfunction and to be aware of the possibility and the implications of the simultaneous presence of nasopharyngeal lymphatic tissue hypertrophy in HIV-infected patients.
