Herpes zoster (HZ) primary affections of the CNS are rare and, in most of the reported patients, are representing variously extended forms of ascending myelitis. Our examination concerns a man who at the age of 37 developed apathy after a feverish episode with iridocyclitis. Six months later an ophthalmic HZ was diagnosed and thenceforth the patient showed a dementia with Korsakow's syndrome, apathy and a right hemipalsy, and diplopia appeared; the later symptoms remitted after steroid therapy. Post-mortem examination revealed a slowly progressive encephalitis with symmetrical impairment of the anterior ventral, medial, and centrum medianum of the thalamus. The HZ origin of the lesions and the relation between their site and the peculiar form of dementia, to be ascribed to the "thalamic" ones, are discussed. A vasculitis process can be hypothesized considering both the symmetrical localisation and the microscopical aspects of the lesions.

A case of necrotizing vasculitis involving the central nervous system in a seven month old Bernese mountain dog is reported. The clinical signs include apathy, fever and increased head and cervical pain. The cerebrospinal fluid was unusual viscous and bloody. In the EEG high activity and spikes were found. A hydrocephalus internus was confirmed by CT scan. On histopathological examination a necrotizing vasculitis on the medulla oblongata and spinal cord leptomeninges with perivascular granulomatous inflammation were detected. The neuropathological lesions are consistent with those reported for the rare disease of necrotizing vasculitis in the central nervous system of Bernese mountain dogs, beagles and boxers. The cause is unknown.

Hepatitis C virus (HCV) infection is often associated with abnormal immunological responses. We describe four patients with vasculitic neurological signs and symptoms following HCV infection. A 56-year-old woman with HCV infection developed peripheral neuropathy characterized by asymmetric distal painful hypesthesia, dysesthesia and moderate motor weakness of the lower limbs. Serological examinations revealed cryoglobulinemia and low levels of complement C4. A biopsy of the sural nerve revealed vasculitic neuropathy. HCV infection associated immunomediated vasculitis was diagnosed. While steroid therapy was ineffective, treatment with interferon-alpha improved the neuropathy considerably without, however, eliminating HCV infection. A 62-year-old man with HCV infection developed peripheral sensory neuropathy. Complement C3 was slightly diminished. Nerve biopsy revealed vasculitic neuropathy. A 71-year-old woman developed chronic symmetric sensomotor polyneuropathy. HCV hepatitis followed blood transfusions. Cryoglobulins tested positive, consistent with type II cryoglobulinemia. Complements C3 and C4 were diminished. Inflammatory infiltrates in the sural nerve biopsy specimen led to the diagnosis of chronic vasculitic disorder. A 55-year-old woman with HCV infection developed vasculitis of the skin, connective tissue, visceral organs, and kidney, leading to hemodialysis. Neurologically she developed severe apathy and drowsiness, myoclonic jerks, exaggerated deep tendon reflexes, and positive pyramidal signs. Magnetic resonance imaging of the brain showed diffuse increased signal abnormalities involving supra- and infratentorial white matter suggesting cerebral vasculitis. Cryoglobulins were positive, complements C3 and C4 slightly diminished (54 mg/dl, 4.3 mg/dl). Supportive therapy resulted in neurological improvement. Treatment with interferon-alpha was discontinued because of agranulocytosis. In patients with peripheral neuropathy or signs of leucencephalopathy, a hepatitis C associated vasculitis should be considered in the differential diagnosis.

A three-year-old, female bulldog was presented with bilateral uveitis, apathy, listlessness, generalised lymphadenopathy and perivulvar haematoma. The initial laboratory studies showed non-regenerative anaemia, polyclonal gammopathy and a high urine protein:creatinine ratio. Serology for leishmaniosis was positive and treatment with allopurinol and meglumine antimoniate was started. Despite treatment, the dog's clinical condition deteriorated. Signs included cutaneous ecchymosis, respiratory distress and finally cardiorespiratory arrest. Histopathological studies of postmortem tissue samples revealed a generalised vasculitis of several internal organs and severe myocarditis. Leishmania species organisms were identified in affected tissues using immunoperoxidase labelling and PCR techniques.

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.

Giant cell arteritis is a systemic disease of unknown origin. Vasculitis involves large and medium-sized vessels. Frequent clinical manifestations include characteristic headache in the temporal area, jaw or tongue claudication, apathy, fatigue, weight loss. The incidence of ocular involvement is reported in up to 70% patients. The most common and serious ophthalmic presentation is arteritic anterior ischemic optic neuropathy, which can lead to irreversible visual loss. Only early and aggressive steroid therapy may prevent this dangerous complication. The authors presented a case of a 68-years-old woman with giant cell arteritis. The main visual manifestation of this disease was anterior ischemic optic neuropathy.

Patient A, 58 years, is referred by the Rheumatologist to the Geriatrician concerning apathy. History reviews skipping arthritis, reddened and inflamed eyes, apathy and loss of interest. Physical examination revealed red tearing eyes, bradyphrenia and bradykinesia. Laboratory examination showed inflammation markers. The patient develops fever and bilateral reddened and inflamed ears. Diagnosis of relapsing polychondritis is made, the patient is treated with prednisone and the symptoms disappear. Relapsing polychondritis is a chronical disease associated with inflammation and destruction of cartilaginous structures and proteoglycan rich structures. We diagnosed Relapsing Polychondritis with a reversible dementia, probably due to cerebral vasculitis.

A 7 mo old female English springer spaniel was presented with diarrhea, vomiting, apathy, and hyperthermia. Further examinations revealed generalized lymphadenomegaly consistent with sterile neutrophilic-macrophagic lymphadenitis and pulmonary involvement. Subcutaneous nodules developed one day after presentation. Histology was consistent with sterile idiopathic nodular panniculitis and vasculitis. No infectious organism was isolated. The dog responded to prednisolone, but relapsed during medication tapering. Cyclosporine had to be added to control the disease. No further relapse had occurred 98 wk after the first presentation. This is an unusual presentation of a systemic sterile neutrophilic-macrophagic lymphadenitis with nodular panniculitis and vasculitis associated with gastrointestinal and pulmonary signs.

We report five male patients, aged 35 to 63 years who suffered from paretic neurosyphilis. The clinical course was that of a subacute dementia with a frontal syndrome, with more apathy than euphoria. All were HIV negative and four were heterosexual. In all, the cerebrospinal fluid had a mononuclear pleocytosis and a positive VDRL. EEG was abnormal in the 3 cases in whom it was performed. One patient in whom a brain angiography was performed, had images of vasculitis. Treatment with 18-24 million units of penicillin per day during two weeks or more, was partially effective.

The cause of the death of a 16-month-old Brasileiro-de-Hipismo filly and a 3-year-old male Paint Horse with clinical manifestations of anemia and apathy from southern Brazil was investigated. These horses were maintained at the same stable; received hay as part of their diet and were submitted for routine necropsy evaluations. Significant gross findings included several nodules randomly distributed throughout the pulmonary lobes of both horses, and the kidneys, myocardium, and the frontal lobes of the cerebrum of the filly. Histopathological evaluation revealed pyogranulomatous bronchopneumonia in both horses; granulomatous interstitial nephritis, myocarditis, and encephalitis were observed in the filly. All lesions contained vasculitis and thrombosis associated with myriads of intralesional, branching, septate fungi consistent with Aspergillus spp.; intralesional fungi were more easily identified by the Grocott methenamine silver stain. Mycological culture of fresh pulmonary sections from both horses and the brain of the filly revealed pure growths of A. fumigatus. These findings confirmed the participation of A. fumigatus in the etiopathogenesis of the lesions observed in the lungs of both horses, and the cerebrum, myocardium and kidneys of the filly and might represent the first description of A. fumigatus-induced encephalitis in horses. Additionally, we believe that infection occurred during the ingestion of contaminated hay or by inhalation of spores within contaminated bedding that resulted in transient nasal mycosis, which progressed to pyogranulomatous bronchopneumonia in both horses with embolic encephalitic, myocardial, and renal dissemination of A. fumigatus occurring only in the filly.
