A case of cerebral cysticercosis is reported in a 49-year-old female who presented with headache, nausea, and vomiting. Lumbar CSF showed the findings of mild aseptic meningitis. CT scan revealed an enlargement of the left ambient cistern and a small cystic lesion in the left frontal cortex. MRI demonstrated multilobular cysts in the left ambient cistern with enhancement of their capsules, which compressed and distorted the midbrain. The cysts were surgically excised, and histological examination of the specimen disclosed characteristic features of cysticercus with viable larva. An excellent value of MRI in the diagnosis of intracisternal cysticercosis is emphasized.

We present 2 cases of Listeria monocytogenes rhombencephalitis (L-RE), both affecting previously healthy adult men. Each of them developed a diphasic syndrome first characterized by fever, nausea and headache, followed, in a second phase, by severe brain stem dysfunction at the level of the pons, with meningism, multiple cranial nerve palsies, ataxia, and, in one case, seizures. The early examination of the cerebrospinal fluid (CSF) demonstrated the presence of Gram-positive bacilli whose typical characteristics were compatible with those of Listeria, allowing for immediate administration of a specific therapy. Neuroimaging techniques (either CT or MRI) did not provide any evidence of brain stem involvement, and they did not positively contribute to the diagnostic process. The immediate use of a specific antibiotic therapy led to a favourable clinical outcome for both patients.

A 58-year-old man was admitted to our hospital with suspicion of aseptic meningitis. He had been well until the day before admission, when he became suffering from headache and nausea. Cerebral spinal fluid (CSF) analysis on admission revealed Cryptococcus neoformans. Neurological examination and brain CT scan showed no abnormality. On the 5th hospital day, he noticed ataxia and weakness in his right extremities and soon fell into drowsy to comatose state. CSF study revealed marked elevation of pleocytosis and oligoclonal IgG bands. The T2 weighted image of brain MRI showed multiple high intensity areas, mainly in the white matter, in cerebellar hemisphere, vermis, left medulla oblongata, left occipital lobe and parieto-occipital lobe. Steroid pulse therapy remarkably improved neurological deficit as well as MRI abnormalities. He became alert at the next day. Ataxia and motor weakness disappeared in a week. Laboratory examination before the pulse therapy revealed impairment of T cell response to mitogens and reduced number of CD8-positive cells. These abnormalities in the cell-mediated immunity were completely corrected by the steroid pulse therapy. It was hypothesized that cryptococcus infection induced the autoimmune mechanism which resulted in the ADEM-like exacerbation.

Before administering tacrine hydrochloride (Cognex), an examination is conducted that includes a medical history, neurological examination, laboratory studies, EEG, CT or MRI, and sometimes lumbar puncture. Much consideration by physicians patients, and caregivers goes into the decision to prescribe Cognex. Aside from a diagnosis of mild to moderate Alzheimer's disease, the patient must be in good health. Patient and caregivers must accept the need for weekly ALT measurements for at least the first 18 weeks of treatment, and for periodic office evaluations. Many of our patients who have received Cognex show considerable improvement in overall sense of well-being, affect, and the abilities to converse and participate in daily activities. The most common adverse effects in our patients are nausea, vomiting, and gastrointestinal upset. In our experience, administration of Cognex extends the time that patients with AD can function in a home environment. This approach often represents a cost savings to the patient's family.

We reported two early-childhood cases suffering from acute optic neuritis (ON). Case 1 was a 3-year-old girl, who had a preceding upper respiratory infection, headache, nausea and subsequent sudden visual disturbance. Cranial MRI revealed multiple T2-elongated lesions in the white matter. She showed two neurological relapses including ON, leading to the diagnosis of clinically probable multiple sclerosis (MS). Case 2 was a 2-year-old boy, who had an acute onset of visual disturbance without any other neurological deficits. MRI with Gd-DTPA enhancement revealed not only a disorder of optic nerves but involvement of the white matter in the acute phase. It has been suggested that there may be a broad spectrum of demyelinating disorders between ON and MS even in early-childhood. Therefore, we should bear in mind to the subsequent progression to MS in childhood ON cases with silent brain lesions.

A 48-year-old woman complained of fever, headache and nausea in October, 1994. Because polymerase chain reaction (PCR) was positive for mycobacterium tuberculosis in her cerebrospinal fluid, she was administered anti-tuberculous drugs. Steroid hormone was also administered for her symptoms of intracranial hypertension. However, multiple intracerebral masses appeared on CT and MRI 2 months later, and have increased in number and size. Cessation of the steroid hormone was impossible as her intracranial hypertension had been deteriorated. She was transferred to our clinic on October 23, 1995. On neurological examination she was drowsy and showed papilledema, weakness of bilateral lower extremities, left cerebellar sign, and bilateral Babinski's reflexes. Enhanced CT and MRI revealed multi-locular lesions in the right fronto-temporal, left temporal and left cerebellar regions. On November 7, 1995 she was operated on. Right fronto-temporal and left cerebellar masses were partially removed. Pathological examination and PCR of the surgical specimens demonstrated tuberculoma. Postoperatively, her consciousness disturbance improved and the residual tuberculomas decreased in size under the influence of anti-tuberculous drugs and cessation of the use of steroid hormone. Recently, tuberculosis is common neither in Japan nor in Western countries. Intracerebral tuberculoma is also very rare. The tuberculosis in our patient with multiple intracerebral tuberculomas resistant to antituberculous drugs was thought to have been induced by decreased resistance to the infection due to the administration of the steroid hormone.

Gadodiamide injection is a new nonionic paramagnetic, extracellular contrast medium. Its safety at a dose of 0.1 mmol/kg body weight was evaluated in a large European multicentre trial on adults referred for contrast-enhanced MRI of the central nervous system. Safety analysis was performed on 2102 patients, in whom adverse events during and up to 24 h after injection were recorded. Adverse events related or possibly related to gadodiamide injection were observed in 102 patients. Injection-associated reactions classified as discomfort (sensation of heat or coldness, pain or pressure at the injection site) occurred in 37 patients (1.8%) and other adverse events (e.g. headache, nausea) were observed in 65 patients (3.1%). No serious adverse event was reported. Efficacy analysis, performed on 2273 patients, and based on comparison of T1- and T2-weighted images before and T1-weighted images after injection showed that more diagnostic information was obtained after gadodiamide injection in 1424 (62.6%) patients: management of 386 (17.0%) patients was affected by the new information given and that a new diagnosis was made in 755 (33.3%) patients. Gadodiamide injection was shown to be safe and well tolerated. It represents a nonionic alternative to the current products for MRI of the central nervous system.

We report a man with a ruptured intracranial dermoid cyst, suffering from headache, nausea, vomiting and a generalised seizure. MRI was performed before and 2 weeks after surgical resection. On T1-weighted images the tumour gave high signal, as did fatty material in the frontal and parietal brain sulci. Identification of this hyper-intense material as lipids was possible by chemical-shift-selective 3D gradient-echo imaging, which provided excellent contrast between the subarachnoid lipids and the adjacent normal brain, with a good spatial resolution. Possible complications of subarachnoid and intraventricular lipid particles after dermoid cyst rupture are discussed and the diagnostic value of 3 D chemical-shift-selective additional to conventional T-1-weighted spin-echo images in identification of even small amounts of fat is emphasised.

A case of right trigeminal neurinoma extending from the cavernous sinus to the cerebellopontine angle in a 48-year-old male is reported. The patient first noticed right facial numbness in June 1993. Six months later, he experienced headaches with occasional nausea, diplopia, ataxic gait, tinnitus and dysphagia and was referred to our department on January 21, 1994. Neurological examination on admission showed multiple cranial nerve palsy from the 4th to 11th nerve on the right, and the cerebellar sign on the right. Initial CT and MRI revealed a large mass lesion extending from the right cavernous sinus to the right cerebellopontine angle. On February 16, 1994, radical resection of the tumor, except the lesion invading the cavernous sinus, was performed via a combined retroauricular and preauricular transpetrosal transtentorial approach. The histological diagnosis was neurinoma. The patient's postoperative course was uneventful and there was good clinical improvement, although the right facial numbness and mild diplopia persisted. On April 6, 1994, radiosurgery was performed with a maximum dose of 28 Gy and a marginal dose to 14 Gy to the remaining cavernous sinus lesion. Two weeks after radiosurgery, the patient achieved a complete return to his daily routine. Two-year follow-up CT and MRI showed a small residual les on in the right cavernous sinus alone. There was no evidence of tumor growth. No new neurological deficits had developed, and the patient's the double vision had resolved. Thus, the patient has been able to maintain a satisfactory level of activities of daily living. We wound like to emphasize the clinical value of the strategy used to treat this patient which combined microsurgery with subsequent radiosurgery.

A 7-year-old boy presented with a 4-week history of daily headache. His parents reported that he was unable to attend school the week prior to presentation. Intermittent nausea without vomiting was reported, but no blurred vision, photophobia, or diplopia were described. There was no history of trauma or recent systemic illness. The physical examination showed mild neck discomfort, no papilledema, and normal cranial nerve, motor and sensory functioning. Both a CT scan of the sinuses and an MRI of the brain were normal. Although the opening pressure was elevated, the cerebrospinal fluid was also normal. In previous accounts of idiopathic intracranial hypertension in children, concomitant papilledema, visual symptoms and/or palsy of the sixth cranial nerve are described. This case demonstrates that idiopathic intracranial hypertension in a young child can present as a daily headache without any visual symptoms or signs.
