Behçet's disease commonly affects 20-40-year-old men and shows ophthalmo-dermatological manifestations. Here, we report a man in his 70s with acute onset of dysarthria, dysphagia and hemiplegia showing brainstem and subcortical lesions, which responded to steroid and colchicine therapy. He had a history of uveitis and was homozygous for the human leucocyte antigen-B51 allele, and we clinically diagnosed him with acute neuro-Behçet's disease. Old-age onset neuro-Behçet's disease is uncommon, and as far as we know, this is the oldest case of the first attack of neuro-Behçet's disease. Clinicians should consider Behçet's disease even for elderly patients., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

The most common neurological manifestation of eosinophilic granulomatosis with polyangiitis (EGPA), formerly called Churg-Strauss syndrome, is mononeuritis multiplex caused by small-vessel vasculitis. In contrast, central nervous system involvement is rare. Among EGPA-associated central nervous system disorders, there are only a few reported cases of hypertrophic pachymeningitis (HP). Here, we report a patient with EGPA with headache and ophthalmoplegia who presented with HP and had a dural biopsy. The biopsy specimen showed lymphocytic inflammatory cell infiltration without EGPA-specific findings, that is, eosinophilic infiltration, granuloma or angiitis. To the best of our knowledge, there are no previous reports of EGPA-associated HP pathology. Here, we report the first case presentation of a patient with EGPA-associated HP with pathological findings., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.
