[en] We report the case of a meningeal inflammatory pseudotumour occurring in a 23-year-old male presenting with focal seizures and headaches. Brain imaging techniques showed a 3.5 cm left parietal meningeal tumour. Histology of the surgical specimen showed a dense lymphoid infiltrate permeating the dura mater and leptomeninges, consisting of a predominant polyclonal B cell population as confirmed by immunophenotyping and genotyping. Cultures of serum, CSF, and surgical specimen were negative and there was no serological evidence of a systemic dysimmune disease. The postoperative course was complicated by an episode of brain oedema resolving under steroid therapy. The patient, free from all medication, is asymptomatic at 3 years of follow-up. We discuss previously published cases and the nosology of intracranial inflammatory pseudotumours.
