Intracranial pseudolymphoma presenting with grand mal seizures

摘要

Primary central nervous system lymphoproliferative disorders comprise a heterogenous group of intracranial disease, predominantly of the high-grade non-Hodgkin's lymphoma type. We report a 56-year-old woman who developed new-onset grand mal seizures and was found to have two small uniformly enhancing dural-based lesions, which were radiologically concerning for meningiomas. Biopsy demonstrated findings consistent with benign, reactive lymphoid tissue. The patient's seizures resolved post-operatively. To our knowledge, this is the first reported patient with intracranial pseudolymphoma presenting as grand mal seizures. This case highlights this rare differential consideration in a patient with symptomatic dural-based lesion.
