ABSTRACT Hypertrophic pachymeningitis is a unique clinical entity characterised by fibrosis and thickening of the duramater with resulting neurological dysfunction. Three cases of this entity are described. Presenting features were headaches and cranial neuropathies in two patients and predominantly cerebellar dysfunction in the third. One of the patients also had evidence of spinal involvement. Lower cranial nerves were chiefly involved in two patients whereas optic nerve was the predominantly affected nerve in one. Except for the presence of rheumatoid arthritis in one of the patients, we could not document clinical or biochemical evidence of any predisposing infective, inflammatory or infiltrative condition in the other two. All three patients had characteristic changes on imaging suggestive of thickened and enhancing duramater. Although variable steroid responsiveness was seen in all the three patients, tendency towards steroid dependence was evident. The clinical presentations, causes, radiological features, management options and differential diagnosis of this unique clinical syndrome have been discussed.

    ABSTRACT: We present an extremely rare case of a patient with focal hypertrophic pachymeningitis in association with histologically proven temporal arteritis (giant cell arteritis). It is proposed that focal hypertrophic pachymeningitis in itself is the contributing factor to severe headache rather than temporal arteritis alone.

    ABSTRACT: A patient is described who developed recurrent headaches following a traumatic injury in the vicinity of the right greater occipital nerve (GON) that fulfill IHS criteria for migraine with aura. Both aura and headache can be triggered by pressure over the GON and relieved by local anesthetic blockade.

    ABSTRACT: Idiopathic hypertrophic cranial pachymeningitis is a rare chronic inflammatory and fibrosing process of unknown etiology. This entity is characterized by fibrosis and thickening of the dura mater and resulting in neurological syndrome. The authors report a 72 year-old woman who presented with progressive bifrontal headache, bilateral visual loss and transient episode of confusion. Neurological examination revealed bilateral optic atrophy, apathy and no focal neurological deficit. Investigations showed anemia of chronic disease, elevated erythrocyte sedimentation rate and polyclonal hypergammaglobulinemia. No specific inflammatory diseases or malignancy such as systemic lupus erythematosus, syphilis, hematologic malignancy were found MRI of the brain revealed thickened and enhanced dura mater and leptomeninges at the inferior aspect of bilateral frontal lobes as well as vasogenic edema of the frontal lobes. Cerebrospinal fluid showed mild pleocytosis, high protein level and normal glucose level. Meningeal biopsy revealed nonspecific inflammatory process of the dura and leptomeninges. There was no granuloma formation or evidence of vasculitis. Special stain for tuberculous bacilli, fungus and malignancy were all negative. The diagnosis of "idiopathic hypertrophic pachymeningitis" was made. The patient was treated with oral prednisolone 45 mg/day. Her headache was improved, but the profound vision loss in both eyes remained unchanged after 2 years of follow-up. Prednisolone was tapered within 18 months. Idiopathic hypertrophic cranial pachymeningitis usually involves dura at tentorium cerebelli, cavernous sinus and base of the skull. The extensive involvement at the anterior cranial fossa is extremely rare.
