A case of Collet-Sicard Syndrome caused by skull base metastasis of prostate carcinoma is reported. A fifty-five years old man presenting multiple lymph node and bone metastases of prostate carcinoma was treated with LH-RH agonist and Flutamide, which induced transient decrease in serum PSA levels and size of lymph node metastases. After 8 months of the treatment, the patient started complaining headache, dysphagia and dysarthria. Brain CT and MRI demonstrated a soft tissue mass replacing left pyramidal bone and occipital bone around left jugular foramen. The tumor was diagnosed as skull base metastasis of the prostate carcinoma and was treated with 50Gy of radiation. The symptom improved after the radiation but died of the disease in 4 months. The autopsy revealed the skull base metastasis of the prostate carcinoma and the tumor was proved to be poorly differentiated adenocarcinoma, which was positively stained by anti-PSA antibody. The case showed cranial nerve palsy of IX to XII, which is usually called Collet-Sicard syndrome. This is the third case report of Collet-Sicard syndrome caused by the skull base metastasis of prostate carcinoma, and it is the first case in Japan.

Haemorrhages in the striatocapsular area, or striatocapsular haemorrhages (SCHs), have been regarded as a single entity, although the area is composed of several functionally discrete structures that receive blood supply from different arteries. We analysed the morphological and clinical presentations of 215 cases of SCHs according to a new classification method we have designed on the basis of arterial territories. SCHs were divided into six types: (i) anterior type (Heubner's artery); (ii) middle type (medial lenticulostriate artery); (iii) posteromedial type (anterior choroidal artery); (iv) posterolateral type (posteromedial branches of lateral lenticulostriate artery); (v) lateral type (most lateral branches of lateral lenticulostriate artery); and (vi) massive type. The anterior type (11%) formed small caudate haematomas, always ruptured into the lateral ventricle, causing severe headache, and mild contralateral hemiparesis developed occasionally. The outcome was excellent. The middle type (7%) involved the globus pallidus and medial putamen, frequently causing contralateral hemiparesis and transient conjugate eye deviation to the lesion side. About 50% of the patients recovered to normal. The posteromedial type (4%) formed very small haematomas in the posterior limb of the internal capsule and presented with mild dysarthria, contralateral hemiparesis and sensory deficit, with excellent outcome in general. The posterolateral type (33%) affected the posterior half of the putamen and posterior limb of the internal capsule and presented with impaired consciousness and contralateral hemiparesis with either language dysfunction or contralateral neglect. The outcome was fair to poor but there were no deaths. The lateral type (21%) formed large elliptical haematomas between the putamen and insular cortex. Contralateral hemiparesis with language dysfunction or contralateral neglect developed frequently but resolved over several weeks. The clinical outcome was relatively excellent except when the haematoma size was very large. The massive type (24%) formed huge haematomas affecting the entire striatocapsular area. Marked sensorimotor deficits and impaired consciousness, ocular movement dysfunctions including the 'wrong-way' eyes were observed quite frequently. The outcome was very poor with a case fatality rate of 81%. The clinico-radiological presentations suggested its origin was the same as the posterolateral type.

We report on a 48-year-old man with idiopathic hypertrophic cranial pachymeningitis (IHCP) manifesting headache, facial pain, and tongue pain with unilateral atrophy, dysarthria, and dysphagia. Although steroid therapy ameliorated these symptoms, they recurred after he developed steroid-induced diabetes mellitus. We treated the patient by lymphocytapheresis (LCP), which resulted in an improvement of his symptoms, a reduction in the CD4 lymphocyte population, a reduction of the CD4/CD8 ratio, and a reduced thickening of the dura mater that lasted for more than 14 months. Results presented here suggest that LCP can be effective in the treatment of IHCP.

Primary leptomeningeal lymphoma (PLML) is a rare disease. The most common presentation is symptoms of increased intracranial pressure. Confusion, dysarthria, hearing loss, paraparesis and lumbosacral spinal root symptoms have also been reported. Chemotherapy and radiotherapy have been tried, but its prognosis is usually poor. We experienced a case of PLML with a relatively benign course in an 18-year-old girl. Initial diagnosis was made as idiopathic intracranial hypertension. Lumbosacral shunt was done with good response for 3 years. When headache recurred, she was reevaluated and was correctly diagnosed as PLML.

A rare case of sarcoid meningoencephalitis with no systemic lesion is reported here. A 58-year old man was admitted experiencing dull headache and speech disturbance. He had never received a diagnosis of systemic sarcoidosis. On admission, neurological examination revealed dysarthria, a defect of the right-side visual field and accelerated right Achilles tendon reflex. A T2-weighted MRI showed a high-intensity signal in the white matter of the left parieto-occipital lobe surrounded by severe brain edema with a mass effect. The meninges around the lesion were enhanced by gadolinium, but no enhancement was observed in the basal portion. Angiotensin-converting enzyme (ACE) activities of cerebrospinal fluid (CSF) and serum were within normal range. The level of interleukin-6 in the CSF was slightly elevated. Chest X ray films and chest CT revealed no abnormal lesions. Whole body gallium scanning showed a hot region only in the intracranial lesion. A brain biopsy was performed. Histological examination revealed typical granuloma of sarcoidosis accompanied by microvasculitis and epithelioid cell granuloma without caseous necrosis. Oral administration of prednisolone improved all symptoms and MRI findings. These observations suggest that release of cytokines from macrophages and epithelioid cells, as well as disruption of the blood-brain barrier due to microvasculitis, are involved in the mechanism responsible for producing lesions of sarcoid meningoencephalitis.

Because of its large spectrum of clinical manifestations, diagnosis of cerebral venous thrombosis may be very difficult. Since appropriate treatment influences prognosis, early recognition of this condition is extremely important. We report a subarachnoid hemorrhage as a rare initial manifestation of cerebral venous thrombosis. A 58-year-old woman was admitted with severe headache of sudden onset, neck stiffness, dysarthria, and ataxia. Computed tomography scan showed a subarachnoid hemorrhage in the right posterior fossa. Magnetic resonance imaging coupled with magnetic resonance angiography revealed right transverse/sigmoid sinus thrombosis with hemorrhagic infarction of the right cerebellar hemisphere leading to a pseudotumoral appearance and displacing the fourth ventricle. Anticoagulant treatment resulted in rapid clinical recovery and in resolution of the radiological signs of infarction and of the subarachnoid and subdural hemorrhages.

We describe a case of a 70-year-old patient with sudden onset of gait ataxia, headache, dizziness and dysarthria. Magnetic resonance imaging revealed a solitary lesion in the left cerebellar hemisphere with strong and irregular enhancement of the contrast medium, surrounded by extensive edema. Rectal examination revealed an abnormally enlarged and stiff left prostate lobe, and ultrasound-guided transrectal biopsies showed prostate adenocarcinoma of mild differentiation. Neurosurgical intervention and histopathologic examination revealed metastatic prostate adenocarcinoma. The patient underwent orchiectomy and was given antiandrogens. He is still alive and closely followed. According to the literature, prostate cancer presenting as a solitary cerebellar metastasis is an extremely rare clinical problem.

Methotrexate-induced neurotoxicity (MTX-Ntox) is a frequent complication of methotrexate (MTX) therapy for patients with both malignant and inflammatory diseases. MTX-Ntox can occur after intrathecal MTX or after low-, intermediate-, or high-dose systemic administration. Symptoms can present in the acute, subacute, or late setting form, and can range from affective disorders, malaise, and headaches, to somnolence, focal neurologic deficits, and seizures. While the pathogenesis of MTX-Ntox is likely multifactorial, one potential biochemical pathway leading from MTX to neurotoxicity involves the folate dependent remethylation of homocysteine (Hcy). MTX therapy is known to cause elevations of both plasma and CSF Hcy. Hcy is directly toxic to vascular endothelium and it and its metabolites are excitatory agonists of the N-methyl-D-aspartate (NMDA) receptor. Competitive or noncompetitive antagonists might afford protection from or reversal of MTX-Ntox. Using high-performance liquid chromatography (HPLC) with coulometric electrochemical detection, the authors measured CSF Hcy in sequential patients with severe subacute MTX-Ntox. CSF Hcy was higher in these patients (n = 9, median = 0.93 microM) than in asymptomatic patients (n = 11, median 0.2 microM, p < .01). Five patients with severe subacute MTX-Ntox (most with dysarthria and/or hemiplegia) were treated with 1-2 mg/kg oral dextromethorphan (DM), a noncompetitive antagonist of the N-methyl-1-aspartate (NMDA) receptor. All five had resolution of symptoms. These data provide additional clinical support for elevated CSF Hcy in the induction of MTX-Ntox through activation of the NMDA-receptor. These data provide support for a placebo-controlled clinical trial to examine the ability of DM to prevent or alleviate MTX-Ntox.

A 66-year-old man, with a history of pulmonary tuberculosis 40 years before admission, complained of headache and dysarthria that lasted for 2 weeks and was followed by diplopia. MRI revealed an isolated nodular lesion in the pons with a marked enhancement mimicking brain tumor and other diseases. Antituberculous drugs were started under the presumptive diagnosis of tuberculoma. The lesion was completely resolved after 9 months of treatment and thus, the final diagnosis was confirmed. An empiric administration of antituberculous drug may be an important and non-invasive diagnostic tool as well as a treatment in such cases.

We report a case with double primary intracranial tumors of different cell types without phacomatosis. The patient was hospitalized due to progressive memory impairment, headaches, dysarthria and right hemiparesis. Initial computed tomographic (CT) examinations revealed a large hyperdense tumor over the right frontal lobe, suggestive of an extra-axial meningioma. Additionally, there was unusual brain edema in the contralateral hemisphere that subsequently proved to originate from an intrinsic tumor. Staged craniotomies were used to treat the patient. Pathological examinations confirmed the two tumors to be a meningioma and a glioblastoma multiforme, respectively. The patient made an uneventful recovery after treatment. Although meningioma and glioma represent two common primary intracranial tumors, the simultaneous development of the two tumors is rare. A randomly occurring event most likely accounted for this linkage in the patient. We suggest that extraordinary brain edema far remote from the primary brain lesion warrants special attention for identifying other potentially undetected lesions.
