Project description:BackgroundFibromuscular dysplasia (FMD) has a high prevalence of associated nontraumatic carotid artery dissection, which could further result in transient ischaemic attack (TIA) or stroke. Limb shaking TIA is an unusual form of TIA that is commonly discribed in elderly patients with atherosclerotic backgrounds, while there are limited data about it in patients with FMD. Furthermore, discussions of limb shaking TIA in nonelderly patients are scarce.Case presentationAn Asian 47-year-old female presented with intermittent involuntary movement of the left upper limb accompanied by neck torsion. The episode stopped soon after changing to the supine position. On native source images of time-of-flight magnetic resonance angiography (TOF-MRA), the right internal carotid artery showed a "dual lumen sign" with an intimal flap. On contrast-enhanced magnetic resonance angiography and sagittal black-blood T1WI, an intravascular haematoma with irregular lumen stenosis was observed, which overall indicated right internal carotid artery dissection. Digital subtraction angiography showed the characteristic "string-of-beads" appearance in the left internal carotid artery, and the presence of this sign pointed to the diagnosis of FMD. The patient was finally diagnosed with limb shaking TIA due to internal carotid dissection with fibromuscular dysplasia. The patient was prescribed dual anti-platelet therapy. The limb shaking vanished soon after admission with no reoccurrence in the three-month follow-up.ConclusionsThis case demonstrates that limb shaking TIA can present in patients with FMD. Limb shaking TIA in nonelderly patients can be caused by multiple diseases, and more detailed patient guidance is required in clinical practice.

Project description:BackgroundSymptomatic bilateral internal carotid occlusive disease is a rare but potentially devastating entity. Medical therapy alone is associated with high rates of mortality and recurrent stroke. The optimal management of this disease remains poorly understood.MethodsA retrospective review of a prospectively maintained database was conducted for patients who presented with an acute stroke in the setting of bilateral carotid occlusive disease between May and October 2013.ResultsWe identified 3 patients. The admission National Institutes of Health Stroke Scale score ranged from 4 to 7. All patients had small- to moderate-sized infarcts in the anterior circulation on presentation. Angiography confirmed bilateral internal carotid occlusions with collateral filling via the posterior communicating artery and retrograde filling via external carotid artery supply to the ophthalmic artery. All patients were initially managed with permissive hypertension and anticoagulation followed by carotid angioplasty and stenting. At 1-year follow-up, all patients demonstrated a modified Rankin scale score of 0-1.ConclusionsCarotid stenting may be a safe and effective therapy for patients presenting with symptomatic bilateral carotid occlusions.

Project description:Limb-shaking transient ischemic attacks (TIA) may occur in patients with insufficient brain perfusion due to an underlying occlusive disease. We present the case of a 64-year-old patient who suffered from repetitive TIA presenting with shaking movements of the right-sided extremities and accompanying speech arrest. Symptoms are documented in the online supplementary video (www.karger.com/doi/10.1159/000327683). These episodes were frequently triggered in orthostatic situations. The diagnosis of limb-shaking TIA was established. The diagnostic workup revealed pseudo-occlusion of the left internal carotid artery, a poor intracranial collateral status and, as a consequence, an exhausted vasomotor reserve capacity. At ultrasound examination, symptoms were provoked by a change of the patient's position from supine to sitting. During evolvement of symptoms, a dramatic decrease of flow velocities in the left middle cerebral artery was observed. This case thus documents the magnitude and dynamics of perfusion failure in a rare manifestation of cerebral ischemic disease.

Project description:Limb-shaking transient ischemic attack (LS-TIA) is a rare clinical manifestation of steno-occlusive carotid lesions. Reports of LS-TIA caused by posterior circulation ischemia are rare. Here, the case of a 56-year-old male patient with a history of epilepsy, who presented with dizziness, nausea and vomiting, is reported. Initial brain magnetic resonance imaging (MRI) indicated no signs of acute ischemia, and the patient's symptoms had not relieved despite drug administration to treat dizziness. During a vestibular function test on the next day, he developed sudden left-limb shaking without disturbance of consciousness or facial twitching. Considering a seizure, an anti-epileptic drug was administered, but no improvement was observed. Eight hours later, the patient experienced left-limb paralysis, and re-examination of the MRI indicated brainstem infarction. The patient recovered well with antiplatelet and antiatherosclerotic therapy. While LS-TIA is a rare manifestation of TIA of the carotid arterial system, posterior circulation ischemia may also manifest as LS-TIA. If a patient presents with limb shaking due to postural changes despite a history of epilepsy, LS-TIA should be highly suspected.

Project description:IntroductionWith the increasingly common operation of mechanical thrombectomy (MT) in acute cerebral infarction cases, iatrogenic CCFs were occasionally reported. All of cases reported type A CCFs, and patients were presented with either asymptom from generation of fistula to duration of postoperative follow-up or distinct presentations at once after MT.Case presentationA 48-year-old postmenopausal female, without history of systemic hypertension and diabetes mellitus, underwent an operation of MT outside our institution about half a year ago. An intraoperative DSA showed an iatrogenic low-flow fistula between meningohypophyseal trunk and ICA. After 4 mouths' postoperative conservative observation, patient's presentation progressed from asymptom to serious optic signs. The patient underwent trans-arterial interventional occlusion. On postoperative day one, visual presentations of patient relieved significantly.DiscussionWe discuss the reason for possibility of iatrogenic injury to meningohypophyseal trunk and clinical progressive presentation. A sudden swerve just beyond derivation of meningohypophyseal trunk is prone to being damaged by a misguided guide wire. The progression of clinical presentation, as a focal point in our case, is not reported in iatrogenic before, but some studys still find that spontaneous dural CCFs are inclined to occur in middle-aged or elderly women, especially in postmenopausal women, so age and sex are regarded as background factors of progressing. In addition, the change of drainage route is an immediate cause of progressive presentations.ConclusionWe expect that when a manipulation of MT is conducted leading an iatrogenic CCF, our neurointerventionist should maintain appropriate vigilance on sex, age, menstrual history and medical history, then take an earlier and timely interventional measure.

Project description:BackgroundMoyamoya disease is a rare chronic steno-occlusive cerebrovascular disease. It may have variable clinical symptoms associated with cerebral stroke, including motor paralysis, sensory disturbances, seizures, or headaches. However, patients with moyamoya disease rarely present with involuntary movement disorders, including limb-shaking syndrome, with no previous reports of limb-shaking syndrome occurring after revascularization procedures for this disease. Although watershed shifts can elicit transient neurological deterioration after revascularisation, symptoms originating from the contralateral hemisphere following the revascularization procedure are rare. Here, we report the case of moyamoya disease wherein the patient developed limb-shaking syndrome derived from the contralateral hemisphere after unilateral revascularisation.Case descriptionA 16-year-old girl presented with transient left upper and lower limb numbness and headache. Based on digital subtraction angiography, she was diagnosed with symptomatic moyamoya disease. Single-photon emission computed tomography (SPECT) showed decreased cerebral blood flow (CBF) on the right side, and she underwent direct and indirect bypasses on this side. Involuntary movements appeared in her right upper limb immediately postoperatively. SPECT showed decreased CBF to the bilateral frontal lobes. Subsequently, the patient was diagnosed with limb-shaking syndrome. After performing left-hemispheric revascularisation, the patient's symptoms resolved, and SPECT imaging confirmed improvements in CBF to the bilateral frontal lobes.ConclusionRevascularization for moyamoya disease can lead to watershed shifts, which can induce limb-shaking syndrome derived from abnormalities in the contralateral hemisphere of the revascularized side. For patients with new-onset limb-shaking syndrome after moyamoya revascularisation procedures, additional revascularization may be warranted for treatment of low perfusion areas.

Project description:Patients with unilateral occlusive processes of the internal carotid artery (ICA) show subtle cognitive deficits. Decline in cerebral autoregulation and in functional and structural integrity of brain networks have previously been reported in the affected hemisphere (AH). However, the association between cerebral autoregulation, brain networks, and cognition remains to be elucidated. Fourteen neurologically asymptomatic patients (65±11 years) with either ICA occlusion or high-grade ICA stenosis and 11 age-matched healthy controls (HC) (67±6 years) received neuropsychologic testing, transcranial Doppler sonography to assess cerebral autoregulation using vasomotor reactivity (VMR), and magnetic resonance imaging to probe white matter microstructure and resting-state functional connectivity (RSFC). Patients performed worse on memory and executive tasks when compared with controls. Vasomotor reactivity, white matter microstructure, and RSFC were lower in the AH of the patients when compared with the unaffected hemisphere and with controls. Lower VMR of the AH was associated with several ipsilateral clusters of lower white matter microstructure and lower bilateral RSFC in patients. No correlations were found between VMR and cognitive scores. In sum, impaired cerebral autoregulation was associated with reduced structural and functional connectivity in cerebral networks, indicating possible mechanisms by which severe unilateral occlusive processes of the ICA lead to cognitive decline.

Project description:IntroductionBreast Cutaneous Horn is a rare case whereby they are basically just nodules composed of keratin projecting above the surface the skin.Presentation of caseA 63-year-old lady, para 6 presented with a horn like growth for the past 2 years associated with itchiness. The horn increased in size to about a length of 5 cm associated with on and off itchiness over the horn. No signs and symptoms of malignancy. As comorbidities, patient has hypertension and dyslipidemia which is well controlled on medications. An ultrasound of the breast revealed cutaneous lesion at upper quadrant associated with adjacent skin thickening and no extension into breast parenchyma. A bedside excision was done and the specimen was sent for Histopathology. Histopathology of the lesion revealed Verruca Vulgaris.DiscussionThis case brings to our attention a rare presentation of cutaneous horn over the breast along with its histological findings helping us to distinguish it with other similar cases. Best management would be by excision and to making sure to get a good specimen of the base for dermatopathological evaluation purpose.ConclusionCutaneous horns are usually benign lesions. However, there are chances of it being malignant. Therefore, it is best for early intervention such as excision followed by histopathological review for further thorough management.
