Intracranial haemorrhage is the most feared manifestation of haemophilia and is usually seen in severe forms. We report herein the case of a 66-year-old HIV-negative patient with mild haemophilia (factor VIII: 7%) who presented with a spontaneous and massive intracranial haematoma causing hemiplegia and aphasia. We discuss the management of this peculiar situation emphasizing the need for rapid and adapted FVIII replacement. A complete recovery was obtained using this strategy combined with initial resuscitation measures and subsequent physical therapy.

We report eight cases of brain tuberculoma. The clinical presentation was polymorphous: partial epilepsy (n=4), headache (n=3), hemiplegia (n=1), meningitis (n=1), cerebellar syndrome (n=1). Six patients also had pulmonary tuberculosis, one had tuberculosis of the genital organs, and one had HIV co-infection. The brain CT scan and MRI were highly contributive to diagnosis and follow-up. Despite good compliance with an anti-tuberculosis regimen for at least 14 months, the course was favorable in only six patients. Adjunction of corticosteroids led to radiological improvement. Assessment of cell immunity demonstrated a diminished immunomodulator ratio. Cerebral tuberculoma should be searched for in patients with unexplained neurological manifestations and several intracerebral lesions, particularly if pulmonary or visceral tuberculosis and/or immunodepression is part of the clinical picture.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the brain caused by the JC virus. It occurs in association with immunodepression due, for instance, to a hematological malignancy, HIV infection, or immunosuppressive therapy for an organ transplant or systemic disease. We describe the fourth reported case of PML in a patient receiving immunosuppressants for Wegener's granulomatosis. A 71-year-old woman receiving azathioprine and glucocorticoid therapy experienced onset of right-sided hemiplegia within a few days, became comatose, and died within a few days. MRI of the brain showed a subcortical lesion in the left parietal lobe generating low signal on T1 images and high signal on T2 images. The initial diagnosis was cerebral vasculitis. However, the postmortem examination showed PML. The diagnosis of PML rests on JC virus detection in the cerebrospinal fluid by PCR assay and on demonstration in a brain biopsy of the typical histological pattern with presence of the JC virus within the demyelinated lesions. No specific or effective treatments are available. Immunosuppressant drugs should be discontinued if possible.

A 38 year-old male presented with an acute onset of left hemiplegia. Brain magnetic resonance imaging (MRI) revealed a bright lesion by diffusion-weighted imaging with low apparent diffusion coefficient value in the right subcortical region, a finding compatible with an acute cerebral infarct. An old infarct was also noted in the same imaging. Both enzyme-linked immunosorbent assay and Western blot method were positive for human immunodeficiency virus infection. The white blood cell count was 2930 cells / mm3, and the subpopulation study for lymphocyte revealed a decreased cluster of differentiation 4+ count of 149 cells/mm3. Studies for prothrombotic states showed decreased protein S and increased anticardiolipin antibodies. We concluded that this was a case of acquired immunodeficiency syndrome (AIDS) with acute and old cerebral infarcts. This patient might be the first reported case in Taiwan. AIDS might be related with stroke in young patients, a condition probably under-recognized in Taiwan.

We report a 47-year-old woman with progressive multifocal leukoencephalopathy (PML). She was a carrier of HTLV-I virus, and developed subacute right hemiparesis and marked motor aphasia. She had a malignant lymphoma in the left neck and basal cell carcinoma in the right inguinal region. Three months after the onset, she became unable to walk because of the right leg weakness or to speak because of motor aphasia. Magnetic resonance imaging (MRI) revealed multifocal T2-high lesions in the white matter of the left frontal lobe, and a brain biopsy revealed demyelinating pathology. A biopsy of the left parotid gland revealed a diffuse pleomorphic type large B cell lymphoma. Although anti-HTLV-I antibody was positive in the serum and cerebrospinal fluid (CSF), no adult T-cell leukemia (ATL) cells were found in the blood or CSF. The patient was then admitted to our hospital. Neurological examinations revealed severe motor aphasia, mild sensory aphasia/cognitive impairment, right hemiplegia, mild right hemihypesthesia, limb-kinetic apraxia in the left hand, idiomotor apraxia, agraphia, perseveration, marked spasticity and brisk tendon reflex in four extremities, and positive bilateral pathological reflexes. MRI showed multifocal T2-high lesions mainly in the cerebral white matter, predominantly in the left hemisphere, and partly in the cerebral cortex. No gadolinium enhancement was found. In addition, 99mTcECD-SPECT showed a broad decrease in cerebral blood flow (CBF) in the cortex. Anti-HTLV-I antibody was positive but anti-HIV antibody was negative in serum. ATL cells were found in 1-3% of the peripheral white blood cells after admission. CSF examination revealed that the cell count (1/microl), protein level (24 mg/dl), and IgG index (0.4) were all normal. However, the myelin basic protein level (321 pg/ml; normal < 102) was increased, JC virus DNA was detected by PCR, and anti-HTLV-I antibody (x 8) was detected in CSF. The regulatory region of the JC virus DNA in the CSF was partly deleted; immunostaining with anti-JC virus protein antibodies revealed the existence of JC virus in biopsied brain specimens, and these findings were consistent with PML. Her symptoms such as motor aphasia, cognitive dysfunction and left hemiparesis were subacutely progressive, and she developed akinetic mutism two weeks after admission. Since the efficacy of cytosine arabinoside for PML has been reported, she was administered 80 mg/day of the drug for five days. After treatment, her communication function was mildly improved but the efficacy was transient. Since it has been reported that HTLV-I, as well as HIV, activates the JC virus promoter and its proliferation, the latent infection of HTLV-I in the central nervous system (CNS) in this case might have stimulated the JC virus proliferation, promoting lesion extension over the cerebral cortex. There have been only a few reports of broad decreases in CBF by SPECT in PML patients. Further MRI and SPECT studies on PML patients are therefore necessary to evaluate the significance of HTLV-I in promoting the JC virus infiltration into the CNS.

Pediatric human immunodeficiency virus type 1 (HIV-1) infection is endemic throughout southern Africa. Neurologic complications are described in 20% to 60% of published series, mostly related to HIV-1 encephalopathy. With increasing HIV prevalence, more atypical cases are presenting. We present, as illustrative cases, seven children (three girls) with unusual neurologic sequelae as a consequence of HIV-1 infection. The median age at presentation was 33 months (range 7 months-6 years). Five of the seven children were developmentally normal before presentation. They presented with progressive multifocal leukoencephalopathy, myelopathy, intractable seizures, acute vasculitis and blindness, hemiplegia, peripheral neuropathy, and paraspinal lymphoma. Neuroimaging of the brain was performed in five patients, of whom one had basal ganglia calcification. All children had poor outcome with incomplete recovery or continued deterioration. In conclusion, children with HIV-1 infection who survive beyond the first year of life can present with a wide variety of neurologic complications. A similar spectrum of neurologic manifestations is likely to occur in other sub-Saharan African countries, characterized by high HIV prevalence. The case histories demonstrate that the neurologic features of pediatric HIV infection do not easily fit into a simplified classification system.

Progressive multifocal leukoencephalopathy (PML) is a fatal neurological disease affecting the central nervous system. JC polyomavirus is the agent related to this disease. PML usually occurs in patients with HIV infection or other immunodeficiencies. We report a case of PML in a patient with idiopathic CD4+ cells deficit. The symptoms began with right arm hyposthenia followed by right hemiplegia. Blood analyses were normal, the only abnormal value was a marked decrease in CD4+ cells count with normal CD8+ cells. The magnetic resonance imaging (MRI) of the brain, showed multiple non-homogeneous lesions without enhancement in the left callous circumvolution and in the sub-cortical left frontal white matter. In the following two weeks, the patient had relevant progression in neurological deficits and a subsequent MRI demonstrated significant worsening. Because of the rapid clinical progression, we decided to start therapy with Cidofovir. The patient, after one month of admission, was slowly worsening in neurological functions.

A 33-year-old Caucasian man with a 17-year history of HIV infection developed sudden right-sided hemiplegia, with the arm more affected than the leg, and aphasia. Magnetic resonance imaging of the brain showed hemodynamic watershed stroke between the anterior and middle cerebral artery territories and an ischemic stroke within the left posterior middle cerebral artery territory. Color-coded Duplex sonography and Doppler sonography revealed hypoechogenic stenosis of the left common carotid artery, the left internal carotid artery, left external carotid artery and right internal carotid artery. An extensive diagnostic workup led us to hypothesize that HIV-associated arteritis was the cause of the stroke, and following intravenous steroid therapy, the carotid artery stenoses vanished.

We report a case of a perinatally HIV-infected patient aged 9 years, who presented with right-sided hemiplegia. His initial CD4 T-cell was of 0.21% (4 cells/muL) and plasma HIV RNA virus of 185 976 copies/mL (log 5.27). Plasma and CSF samples were subsequently positive for JCV. Twelve days after the initiation of highly active antiretroviral therapy (HAART), the MRI showed progressive white matter lesions with asymmetrical deep and subcortical white matter lesions over the left frontotemporoparietal region and the right frontal lobe. Immune Reconstitution Inflammatory Syndrome (IRIS) was suspected, and the patient was treated with methylprednisolone. His clinical symptoms worsened and despite therapy the patient deteriorated.

A male intravenous drug abuser who was infected with hepatitis B and C, presented with a slowly progressive hemiplegia. Contrast enhanced computerized tomography of the head showed a solitary ring-enhanced mass with surrounding edema. Clinically brain tumor was suspected but a brain biopsy confirmed cerebral toxoplasmosis. An HIV test was not considered until the result of brain biopsy. He also had lymphopenia and positive serum toxoplasma antibody. His subsequent HIV test was positive. He deteriorated after a brain biopsy. Empirical antitoxoplasma treatment is recommended in HIV-positive patients with ring-enhanced lesions with surrounding edema and with positive toxoplasma serology. Cerebral toxoplasmosis is still the commonest cerebral opportunistic infection in HIV-infected patients even though the incidence has declined with the use of antiretroviral therapy. It is often diagnosed in those patients as an initial presentation of HIV infection or in those who failed to attend for disease monitoring. Clinical features and differential diagnosis of cerebral toxoplasmosis in immunocompromised patients are discussed.
