Dural Graft-Induced Fibrotic Mass Twelve Years after Successful Treatment of Skull Base Non-Hodgkin Lymphoma Mimicking Recurrence: Case Report and Literature Review

摘要

Non-Hodgkin lymphoma involving the skull base is a very rare tumour. The role of surgery for these patients remains controversial, as is the use of dural graft for CSF leak repair. With an increasing incidence of CNS lymphoma, more atypical presentations are reported. It is, therefore, important to include lymphoma in the differential diagnosis of skull base lesions as long-term remission is achievable for such patients, as shown in our case. Dural graft used for CSF leak repair could present with delayed complication mimicking tumour recurrence. Relevant published literature is reviewed.
