A 65-year-old woman with diabetes mellitus and chronic otitis media developed headache, fever, and hoarseness, all of which did not responded to the oral antibiotics. As stiff neck and lower cranial nerve palsies appeared, bacterial meningitis was suspected. Neurological examination revealed the right hearing disturbance, right recurrent laryngeal nerve palsy, left sternocleidomastoid muscle atrophy and bilateral tongue atrophy. The CSF examination revealed mild pleocytosis and elevated protein, but no bacterial organism was cultured from the CSF. CT scans showed bilateral mastoiditis, and the right mastoid process and a posterior part of the petrous bone were eroded, indicating the exposed bony structures to the posterior fossa. MRI scans demonstrated the thickening of the dura mater of the posterior fossa and the right cerebellar tentorium. This is a rare example of bacterial pachymeningitis of the posterior fossa, the clinical symptoms and MRI findings of which resolved solely by antimicrobial agents without corticosteroid.

Idiopathic hypertrophic cranial pachymeningitis is an infrequent chronic inflammatory process of unknown etiology which causes thickening of the dura mater and progressive neurologic alterations due to the compression of adjacent structures. A case is presented of an adult woman with a clinical syndrome consisting of headache, progressive visual loss and bilateral optic neuropathy. The diagnosis was based upon visualization of the thickened dura mater in neuroimaging studies and the exclusion of known causes by histopathological examination. Diagnosis and follow-up of this condition are currently easier with the use of nuclear magnetic resonance with contrast medium. Biopsy of the dura mater continues to be the gold standard for the definitive diagnosis of this disease. Steroid therapy causes clinical improvement in most of the patients; however, relapses are frequent, making necessary the concomitant use of other immunosuppressive agents such as cyclophosphamide or azathioprine. Mortality is low but definitive neurologic sequelae are common.

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.

Pachymeningitis is an inflammatory process that thickens the dura mater. This disease has various etiologies including infectious, neoplastic, or autoimmune diseases. We present the case of a patient who developed cranial pachymeningitis with a clinical and biological picture suggestive of a neurological form of vasculitis. A 51-year-old woman developed rhinitis, otitis media, headaches, and deterioration of her condition after a course of recombinant hepatitis B vaccine. After a booster dose of the vaccine, she developed unilateral visual loss and impairment of multiple cranial nerves. Blood analysis showed inflammation and presence of antimyeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA). Cranial magnetic resonance imaging (MRI) showed pachymeningitis. A complete remission was obtained with immunosuppressive therapy. The initial clinical presentation and subsequent remission under immunosuppressive therapy were suggestive of a vasculitis with nervous system involvement. Though vasculitis was not proven histologically in this patient, we believe that MPO-ANCA-related autoimmunity provoked the patient's disease as already reported in similar cases. As pachymeningitis is a fibrosing process, early recognition and treatment of an autoimmune etiology, even in the absence of previous pulmonary or renal involvement, is required to prevent definitive neurological impairment.

In this report, we present a rare case of a 52-year-old man with a unique form of hypertrophic pachymeningitis involving the anterior part of the falx and who was positive for rheumatoid factor. The clinical symptom was only headache, without any cranial nerve palsies or ataxia. Diagnosis was made by gallium scintigraphy and magnet resonance imaging but was not confirmed by dural biopsy. Treatment with corticosteroid alone was extremely effective for him, while in most cases hypertrophic pachymeningitis recurs or progresses despite the treatment.

Pachymeningitis is a very rare neurologic manifestation of polyarteritis nodosa (PAN). This report describes a case of acute pachymeningitis that was, initially, misdiagnosed as subdural hematoma on the brain CT of a patient with PAN. A 45-year-old man, who had been diagnosed as having PAN 6 months previously, came back to the emergency room with complaints of sudden headache, nausea, vomiting, and diplopia for 3 days before his hospital admission. Initially, the noncontrast enhanced brain CT findings showed high densities in the bilateral tentorial and posterior parafalcial area, which suggested a small amount of subdural hematoma. However, the subsequent MRI findings revealed pachymeningitis of the bilateral tentoria and falx. He was treated with high-dose steroid and cyclophosphamide pulse therapy. Thereafter, his symptoms gradually resolved.

Hypertrophic pachymeningitis is a rare disorder characterized by meningeal thickness, that can be caused by infection, tumoral infiltration, inflammatory disorders or idiopathic. We report the case of a 40 year-old man that presented with longstanding headache and progressive bilateral visual loss and proptosis. Cranial and orbital magnetic resonance imaging revealed diffuse dural thickness and bilateral extraconal orbital lesion. Extensive investigation did not reveal any systemic condition. Histopathological study after meningeal and orbital biopsy disclosed a chronic inflammatory process compatible respectively with idiopathic hypertrophic pachymeningitis (IHP) and orbital pseudotumor. This case emphasizes that orbital involvement can occur in IHP and that its early identification is of great importance in order to improve the visual prognosis of this condition.

Hypertrophic cranial pachymeningitis is an uncommon, fibrosing, inflammatory process that involves the dura mater. The condition is being reported more frequently owing to the use of cranial MRI. The main clinical feature is headache, whereas cranial nerve lesions, cerebellar symptoms, and epileptic seizures occur more rarely. A variety of autoimmune and infectious diseases can result in this condition, which is labeled as idiopathic in the absence of any definite inciting factor. The diagnosis of hypertrophic cranial pachymeningitis is based on neuroimaging of thickened and enhancing dura mater. It can be defined pathologically on biopsy. A specific treatment is indicated in some cases of secondary hypertrophic cranial pachymeningitis. Mostly, treatment relies on corticosteroids and immunosuppressive agents. This review summarizes the current knowledge on causes, clinical presentation, diagnosis, and treatment of this disorder.

This report describes a 69-year-old woman who presented with acute monocular visual loss, ipsilateral headache, and elevated sedimentation rate (ESR) and C-reactive protein (CRP). Both temporal artery biopsies were negative. Neuroimaging, dural biopsy, and breast biopsy all confirmed the diagnosis of carcinomatous hypertrophic pachymeningitis associated with metastatic breast carcinoma. After treatment with corticosteroids, her vision improved. Her clinical presentation initially mimicked the symptoms and signs of giant cell arteritis. Acute monocular visual loss without other cranial nerve palsies may be an uncommon presentation of hypertrophic pachymeningitis from metastatic breast carcinoma.

A 33-year-old female who had been on a steroid treatment for the past 14 years due to systemic lupus erythematosus (SLE) visited our hospital complaining of mild headache. No neurological deficit and no positive serologic tests for lupus anticoagulants (LAC) and anticardiolipin antibodies (aCL) were noted. Only a mild inflammatory change was observed on routine hematological examination. On neuroradiological examination, MRI revealed thickened falx cerebri and tentorium cerebelli, and an empty delta sign. These findings were suggestive of sinus thrombosis of superior sagittal sinus (SSS). Angiograms clearly demonstrated occlusion of the posterior part of superior sagittal sinus and transeverse sinus (TS). Conservative treatment was chosen because of no evidence of intracranial hypertension. There was no deterioration in her general and neurological status during her hospital stay and she was discharged. Longstanding vasculitis and pachymeningitis related to lupus erythematosus might be the probable cause of the sinus thrombosis in this case.
