A 48-year-old female was seen because of left orbital pain. The neurological findings were normal at her first visit. She presented temporary double vision during conservative period. Plain CT revealed no mass around the sellar region. Enhanced CT revealed enhanced mass in the left cavernous sinus. MRI revealed low intensity lesion on both T1 and T2 weighted images. Enhanced MRI showed strongly enhanced mass extended from the left cavernous sinus to the dura of sellar floor, the contralateral cavernous sinus, and cerebellar tentorium. Angiography showed stenosis of the left internal cerebral artery. Biopsy from the dura of the tentorium was performed via anterior temporal approach. Abundant collagen fibers with hyalinization were seen in the thickened dura. A final diagnosis of idiopathic cranial hypertrophic pachymeningitis presenting Tolosa-Hunt syndrome was made. Symptoms were free just after the surgery, however, the regrowth of the tentorial lesion was found on MRI after one year. The size of the lesion decreased after administration of steroid.  相似文献

We report 2 cases with cavernous sinus dural arteriovenous fistula (C-dAVF) presenting with headache as an initial symptom. A 70-year-old woman complained of acute persistent headache in the right temporal region. Another 74-year-old woman suffered from sudden and severe headache, developing from right-sided temporal throbbing to bilateral headache. Her condition was also complicated with cranial nerve deficits. These two patients were finally diagnosed as having C-dAVF based on the results of magnetic resonance angiography and cerebral angiography. It was difficult to make rapid diagnosis of C-dAVF in our patients, because they presented with headache alone but no typical symptoms of C-dAVF, such as proptosis, conjunctival injection or orbital bruit. C-dAVF should be considered as an important differential diagnosis in patients with headache.  相似文献

We report a 41-year-old man whose initial neurological symptoms are atypical of Wegener's granulomatosis. The patient was admitted because he developed left ocular pain, headache, bilateral visual loss and left abducens nerve palsy. He was initially diagnosed with optic neuritis at ophthalmological department and steroid therapy was started. Although steroid therapy led to rapid recovery of visual acuity and eye movement, he was readmitted for seizure. Two weeks later, a second seizure attack occurred, followed by palsy of the left side of cranial nerves II, III, IV, V and VI. Brain MRI showed focal thickening and enhancement of the dura mater over left frontal lobe, leading to a new presumptive diagnosis of idiopathic hypertrophic cranial pachymeningitis. Steroid therapy was resumed and the symptoms improved rapidly. As right hemiparesis developed during the clinical course, another brain MRI was obtained. T2-weighted image showed a high intensity area in the left portion of the pons. 14 months later, recurrent epistaxis suggestive of Wegener's granulomatosis appeared. A subsequent nasopharyngeal mucosa biopsy revealed a necrotizing granulomatous inflammation. A significant elevation of PR-3 ANCA was also noted. A definitive diagnosis of Wegener's granulomatosis was established. The initial presentation of this case was of multiple cranial neuropathies with no superior respiratory tract symptoms, which are typical of early stage Wegener's granulomatosis. In patients with various central nervous system symptoms and MRI evidence of hypertrophic cranial pachymeningitis, a thorough clinical workup of vasculitis syndrome including Wegener's granulomatosis should be considered.  相似文献

We here present two cases of hypertrophic cranial pachymeningitis exhibiting unique multiple cranial neuropathies, both of which were associated with otic and paranasal infections. Case 1: A 76-year-old woman developed headache after undergoing surgical dilatation of the external auditory canal, with subsequent development of a bacterial infection. Neurological examination reveled only bilateral hearing disturbance. MRI and CT scans demonstrated thickening of the dura mater and inflammatory granulation around the left cerebellar tentorium. Based on a diagnosis of hypertrophic pachymeningitis associated with previous infection, antibiotics were administered, followed by oral prednisolone therapy. This treatment relieved the headache and improved the MRI findings. However, 2 months later, the headache became worse and impaired movement of the soft palate, atrophy of the left side of the tongue, and atrophy of the sternocleidomastoideus muscle were noted. MRI revealed aggravated inflammatory changes around the left cerebellar tentorium and their expansion into the jugular foramen. Occlusive changes in the transverse and sigmoid sinuses were also seen. Case 2: A 78-year-old man developed bilateral visual loss, right frontal headache, and bilateral restriction of eye movement. He had been treated for phemphigus with prednisolone and azathioprine. MRI showed hypertrophic dura mater spreading continuously from the frontal base and ethmoid and frontal sinuses to the falx and right frontal lobe. Since Pseudomonas aeruginosa was cultivated in biopsy specimens from the dura mater, antibiotic agents were administered. The clinical symptoms resolved and MRI findings gradually improved.  相似文献

A case of hypertrophic cranial pachymeningitis developed skull lesion]   总被引:3,自引:0,他引:3  
We report a case of hypertrophic cranial pachymeningitis (HCP) developed skull lesion. A 70-year-old male presented with the symptom of left hemiconvulsion. MRI revealed that the enhanced intraosseous mass infiltrated into the the dura and brain parenchyma under the parasagittal region of the right parietal bone. Histological examination revealed chronic inflammation with lymphoplasmacytic infiltrate and fibrosis of both intraosseous mass and dural invasive lesion. Steroid therapy resulted in improvement of clinical symptoms and enhanced lesion of MRI. Three years later, the patient presented with generalized convulsion and weakness of right upper and lower limbs. MRI revealed dural thickening with gadolinium enhancement in the bilateral parasagittal region and falx. Angiography showed occlusion of the superior sagittal sinus. The cause of relapsing symptoms in this patient may have been related to the occlusion of the superior sagittal sinus, due to HCP. We considered that the incipient intraosseous mass resulted from a response of the marrow by destructive progression of chronic inflammation passed through the fracture crack or the cavity of arachnoid granulation.  相似文献

We report two cases of idiopathic carotid-cavernous fistula (CCF) with primary symptoms of headache and diplopia. A 47-year-old woman presented with throbbing headache in her right frontal region followed by right trochlear nerve palsy. Brain magnetic resonance imaging (MRI) was normal but magnetic resonance angiography (MRA) and computed tomographic angiography (CTA) revealed abnormal signals around the right cavernous sinus. CCF was diagnosed by conventional angiography. The symptoms improved naturally but after about 1 year she suddenly exhibited conjunctival congestion. A 41-year-old man complained of fluctuating headache with sudden left abducens nerve palsy. MRI and MRA were normal but CTA showed abnormal signals around the left cavernous sinus. A final diagnosis of CCF was made by conventional angiography and he was transferred to another hospital for stereotactic radiosurgery. Diagnosis of CCF tends to be delayed in cases presenting with only headache and external ophthalmoplegia. However, CCF with cortical vein drainage can lead to cerebral hemorrhage and early correct diagnosis is needed. Our cases showed a dilated superior ophthalmic vein in enhanced CT and an abnormal signal around the cavernous sinus in CTA. Therefore, CTA may be useful as a relatively non-invasive method that can provide diagnostic clues for CCF.  相似文献

We report two cases of so-called 'thalamic astasia', associated with thalamic infarction. A 76-year-old-man suddenly noted to fall down to the left side without severe hemiparesis. An MRI showed an infarction in the superolateral portion of the right thalamus. Over eight weeks, his astasia gradually disappeared. A 69-year-old-man suddenly noted inability to stand with loss of balance. He showed mild hemiparesis, hypesthesia and cerebellar signs on the right side. Although right hemiparesis was slight, he was unable to stand by himself. An MRI demonstrated an infarction in the ventrolateral to ventroposterior portion of the left thalamus. Three weeks later, his symptoms except for cerebellar ataxia remarkably disappeared. The overlapped MRI lesions of these two cases were localized in the ventrolateral thalamus, such as Vimi (nucleus ventrointermedii internus), Vci (nucleus ventrocaudalis internus), Cemc (nucleus centralis thalami magnocellularis). These lesions are so-called 'vestibular thalamic nuclei', in which fibers from vestibulocerebellum are terminated. Involvement of the thalamic connectivity explains that two patients noted inability to stand. Thus we concluded that these two patients had thalamic astasia, described by Masdeu and Gorelick.  相似文献

We presented a 70-year-old woman who developed unilateral visual loss due to central retinal vein occlusion caused by chronic hypertrophic cranial pachymeningitis. She had developed right blindness with optic atrophy due to chronic intracranial pachymeningitis one year before admission. In June 1999, she noticed visual loss of the left eye. On admission, neurological examination revealed left visual loss and sensory impairment in the first branch area of bilateral trigeminal nerves. Ophthalmological examination revealed central retinal vein occlusion of the left eye. Brain MRI showed dural thickening with gadolinium enhancement of the cavernous sinus near the left optic nerve and dilatation of the left supraorbital vein. There was no compression of the left optic nerve. We suggest that central retinal vein occlusion may be caused by compression of the supraorbital vein by dural thickening. This is the first case report of central retinal vein occlusion associated with chronic hypertrophic cranial pachymeningitis.  相似文献

The authors reported the first case of a dissecting aneurysm of the anterior cerebral artery (ACA) presenting only with headache successfully treated by trapping. A 23-year-old man was admitted to our department due to headache. CT scan and MRI showed neither hemorrhage nor infarction. Angiography demonstrated an aneurysmal dilatation at the right A1 segment with venous pooling which suggested a dissecting aneurysm. We performed trapping and resection of the aneurysm without neurological deficits. The natural history of intracranial dissecting aneurysm without ischemia and/or hemorrhage is still unclear, and therefore it is controversial about the necessity of surgical intervention. Our case and review of the literature suggest that surgical treatment should be considered even in patients without ischemia and/or hemorrhage, if it is possible in consideration of hemodynamic condition.  相似文献

We describe two patients with generalized tetanus, a 60-year-old man and a 76-year-old woman, presenting with dysphagia as an initial symptom of the disease. Eighty percent of patients with generalized tetanus manifest dysphagia on admission to a hospital. However, dysphagia is rare as an initial symptom. Both our patients had dysphagia as their initial symptom, followed by neck stiffness and trismus. We made a diagnosis of generalized tetanus based on these neurological findings in the absence of an apparent episode of trauma. After the administration of tetanus immunoglobulin on admission, they recovered without exhibiting generalized convulsion, autonomic storm, or any other serious complications. The vaccination of tetanus toxoid cannot maintain sufficient antibody titers more than ten years. Therefore, elderly people are considered susceptible to tetanus. We suggest that tetanus should be considered in the differential diagnosis of dysphagia particularly in elderly patients. We also suggest that treatment of tetanus should be initiated immediately, because tetanus still has a high mortality rate at present.  相似文献

We described three cases of hypnic headache with successful treatment by lithium carbonate or caffeine. This is the first detail report of Japanese cases. An endocrinological test and rhythm analyses of ambulatory blood pressure (ABP) and heart rate variability in a case suggested possible association between hypnic headache and hypothalamic-pituitary dysfunction. Case 1: A 48-year-old female migraineur complained of new-onset nocturnal headaches. Her headache awakened her from sleep between 1 AM and 2 AM. The headache occurred 3-4 times per week and lasted from 1 hour to 2 hours. The headache were moderate intensity and bilateral dull throbbing pain that located in the forehead to temples. There was no accompanying symptoms such as nausea, phonophobia, photophobia, nor the other autonomic features including conjunctival injection or tearing during the headache attacks. Physical and neurological examinations showed normal results except slight weakness and mild dysesthesia of the left arm due to a vertebral disk herniation at C5/6 level. In the pituitary endocrinological test, the prolactin level remarkably increased in response to the TRH loading. The single cosinor analysis demonstrated significant circadian rhythm of ABP parameters. However, the analysis did not demonstrate any significant circadian rhythm of Holter ECG parameters of time domain analysis and frequency analysis. Receiving 200 mg lithium bicarbonate before sleep, her nocturnal headache completely disappeared. Case 2: A 68-year-old woman had been followed up by her chronic tension-type headache since her forties. At her 66-years, she suffered from a new nocturnal headache. She awoke from sleep by the headache about 3 AM and the headache lasted 30 min. Moderate, dull headache located on her left temple to parietal head, 3-4 times/week. She was able to go back asleep without any medication after spontaneous headache cessation. She first complained the nocturnal headache at the 10 months later of the new headache appearance. She received 200 mg caffeine just before sleep and her headache has been disappeared. Case 3: 70-year-old women had been regularly visited our clinics for her migraine and chronic tension-type headache. She received amitriptyline and her headaches was well controlled. At her 69 years, she complained nocturnal headache. It occured every other day. The headache was moderate pulsative dull pain on the occipital region and lasted 90 minutes without any autonomic symptoms. Headache began between midnight and 1 AM. She told us her new nocturnal headache one year later of the onset. Oral caffeine (200 mg) just before sleep did not improve her headache and caused insomnia. Receiving 100 mg lithium before sleep, her hypnic headache disappeared completely. These three cases are compatible with the diagnostic criteria proposed in ICHD-II. There were some patients with hypnic headache in Japan and neurologists should pay attentions to this form of benign headache, because some beneficial treatments are currently available.  相似文献

We report a 54-year-old female with rheumatoid factor-positive hypertrophic cranial pachymeningitis. At age of 51 years she developed headache, hearing loss, right vagal nerve palsy, and right accessory nerve palsy. MRI revealed thickening and gadolinium-enhancement of the cranial dura mater. The initial symptoms significantly improved with corticosteroid therapy. Two years later, she presented with severe headache and neck pain. Although gadolinium-enhanced MR images failed to show any change compared with those before recurrence, 201Tl single-photon emission CT (SPECT) showed a remarkable accumulation of thallium-201 in the dura mater. Furthermore, the abnormal uptake of thallium-201 returned to normal after treatment with corticosteroid. 201T1-SPECT was a useful tool for the evaluation of disease activity in the patient with hypertrophic pachymeningitis.  相似文献

We report an unusual case of dysembryoplastic neuroepithelial tumour (DNT) located in the occipital lobe presenting with only headache. A 31 year old woman presented with headache. She had no history of epilepsy and neurological examination revealed no abnormal findings. Computed tomography (CT) scanning revealed a multilobulated mass lesion with calcification in the right occipital lobe. Magnetic resonance (MR) imaging demonstrated a heterogeneously enhanced mass with hypointense signals on T1- and hyperintense signals on T2-weighted images. The lesion was totally resected and histopathologically diagnosed as DNT. Physicians must bear in mind that DNT may occur in the occipital lobe and present with only mass effect.  相似文献

We performed 123I-IMP-SPECT to patients with Down's syndrome who were supposed to have neuropathological findings of dementia of the Alzheimer's type. In case 1, a 52-year-old man with dementia, bilateral posterior parietal low uptake and right temporal low uptake were noted. Uptake was markedly lower in the right hemisphere. Case 2, a 38-year-old man not exhibiting clinical features of dementia, presented slightly decreased uptake in bilateral posterior parietal areas. We conclude that the patterns of abnormally decreased uptake in these cases of Down's syndrome are similar to those in dementia of Alzheimer's type, and that there is a possibility to detect the predemented stage of Down's syndrome by 123I-IMP-SPECT.  相似文献

We report herein two cases of nemaline myopathy which showed peculiar muscle involvement and clinical symptoms. Case 1: A 44-year-old woman had developed gradual woresening of muscle weakness. Neurologically, only flexion of her neck was found to be weak. Her muscular CT revealed mild atrophy of four extremities and the sternocleidomastoid muscles. Histological examinations with Gomori-trichrome staining revealed tiny structures whose form was compatible with nemaline rods. Moreover, electronmicroscopic examination demonstrated the lattice pattern of electron-dense structures, and they also appeared to possess structural continuity with the Z-band. Case 2: A 56-year-old woman visited our department because of neck pulsations. Neurological examinations revealed bilateral hearing disturbance, marked atrophy of neck muscles, muscle weakness in four extremities and hypoactive deep tendon reflexes. She also exhibited steppage and waddling gaits. Her muscular CT demonstrated degenerative processes in the neck muscles(splenius muscles and semispinal muscles), trapezius muscles, para-spinal muscles, deltoid muscles and gluteal muscles. Among them, the para-spinal muscles and extensor muscles of the lower limbs showed marked degeneration and had been partly replaced by fatty tissues. A muscle biopsy was performed, and the presence of nemaline rods was confirmed by Gomori-trichrome staining. Although these two cases could be diagnosed as nemaline myopathy, the clinical symptoms and muscular CT findings were not quite the same. Whether these differences might simply indicate different clinical phases during the disease progression or be of further pathogenic significance still remains unclear. Additionally, since long-term follow-up studies of nemaline myopathy are quite rare, further follow-up examinations of these cases are necessary in order to understand the clinical and pathological alterations of nemaline myopathy.  相似文献
