We report a case of a 26-year-old man diagnosed with nasal-type extranodal natural killer/T cell lymphoma (ENKTL) extending beyond the nasal cavity. Complete response was achieved after therapy, followed by rapid metastasis to the meningeal nerve fibres. The overall survival (OS) of the patient was 15 months. To better understand ENKTL with meningeal involvement, we summarized the clinical features of the 10 cases involving meningeal metastasis in ENKTL reported in the English literature.


The patient was admitted for the ENKTL diagnosis, and positron emission tomography-computed tomography showed the disease stage and response. When central nervous system (CNS) infiltration was suspected, magnetic resonance imaging (MRI) of the brain and spinal cord was performed, as well as cerebrospinal fluid (CSF) analysis with flow cytometric immunophenotyping.


MRI of the brain and spinal cord revealed normal results. CSF analysis with flow cytometric immunophenotyping showed NK/T lymphoma cell infiltration.


Meningeal metastasis of ENKTL is rare; when patients present with nervous system symptoms, CNS metastasis should be considered as a possibility, even in the early stage. The OS of our patient was 15 months, which is the longest survival time reported in the literature, probably due to early diagnosis and comprehensive management, including intrathecal therapy, chemotherapy and radiotherapy of the whole brain and spinal cord.
