Left ventricle cardiac myxoma as a cause of ischaemic stroke in young patient treated by mechanical thrombectomy.
We present a case of a young 21-year-old woman with no symptoms of dyspnoea who suddenly developed expressive aphasia and right-sided hemiparesis due to a thrombus in the left middle cerebral artery followed by the left anterior cerebral artery. She underwent acute mechanical thrombectomy with improvement of the neurological status. Bedside ultrasonography detected a suspected myxoma, which was further confirmed by a CT scan as a myxoma in the left cardiac ventricle. The patient underwent successful surgery. We stress on the importance of echocardiographic examination in young patients after ischaemic stroke and multidisci...

Embolic Stroke Due to a Mural Thrombus in the Ascending Aorta Following Cisplatin-based Chemotherapy.
Authors: Ochiai Y, Tsunogae M, Ueda M Abstract A 59-year-old woman with small-cell lung carcinoma achieved tumor disappearance after cisplatin-based chemotherapy (CBC) and radiation treatment but subsequently experienced right hemiparesis and aphasia. Brain magnetic resonance imaging revealed a left middle cerebral artery territory acute infarction and left internal carotid artery occlusion. Ultrasonography revealed a mobile thrombus in the left common and internal carotid arteries, and contrast computed tomography revealed a mural thrombus in the ascending aorta. Based on these findings, embolic stroke due to aort...

Tumor Embolism Through Right-to-Left Shunt Due to Venous Invasion of Esophageal Carcinoma
A 69-year-old man was admitted to the hospital with right hemiparesis and global aphasia. Perfusion computed tomography imaging revealed ischemic penumbra in the middle cerebral artery territory. Angiography showed left middle cerebral artery occlusion. Mechanical thrombectomy with one pass was performed, and successful recanalization was obtained. Embolic material was retrieved; it contained tumor fragments with atypical keratinizing squamous cell carcinoma. Contrast computed tomography imaging indicated tumor invasion into the superior vena cava, and contrast transcranial Doppler indicated the presence of a right-to-left...

Dynamic assessment of internal carotid artery and elongated styloid process in a case of bilateral carotid artery dissection.
Conclusion: We showed that repeated attachment of the styloid process and ICA may trigger an ICA dissection during head rotation. This finding would be helpful for understanding the causes of vascular Eagle syndrome. PMID: 32637216 [PubMed]

Carotid artery stenting before surgery for carotid artery occlusion associated with acute type A aortic dissection: Two case reports.
CONCLUSIONS: In the present cases, although ischemic stroke was serious and precluded surgical indication for ATAAD, carotid artery stenting before surgery for ATAAD resulted in good clinical outcomes. Performing carotid artery stenting before surgery for ATAAD is challenging but achievable, and is a valid treatment option depending on the individual cases.

Neuro-Clinical signatures of language impairments after acute stroke: a VBQ analysis of quantitative native CT scans.
CONCLUSION: In summary, the method applied to nCT scans performed in the acute stage of stroke provided robust and accurate information about brain lesions' location and size, as well as quantitative values. We found that nCT and VBQ analyses areeffective for identifying neural signatures of concomitant language impairments at the individual level, and neuroanatomical maps of aphasia at the population level. The signatures explicate the neurophysiological mechanisms underlying aetiology of the stroke. Ultimately, similar analyses with larger cohorts could lead to a more integrated multimodal model of behavior and brain ana...

Left thalamus infarction in the thalamotuberal artery perfusion area causing subcortical diaschisis and transcortical sensory aphasia
The thalamus is related to language function, and some thalamic stroke cases can cause aphasia [1]. However, most previous cases reporting thalamic damage-induced ipsilateral subcortical diaschisis and aphasia were hemorrhagic stroke [1,2]. Only a few left thalamus infarction cases showed cortical hypoperfusion concerned with the aphasia, but no single-photon emission computed tomography (SPECT) or thalamic nucleus data were available [3]. Thus, aphasia pathology due to cortical hypoperfusion following thalamus infarction, especially with respect to thalamic nuclei, is still unknown.

“Accent issue”: foreign accent syndrome following ischemic stroke
In conclusion, FAS is a rare motor speech disorder, often related to cerebrovascular accidents involving critical regions in the dominant hemisphere. In addition, the present case adds further evidence to the role of the left primary motor cortex in modulation of prosody. In rare cases FAS can be the only sign of stroke or can appear after recovery from post-stroke aphasia.

Neurophysiological predictors of aphasia recovery in patients with large left-hemispheric infarction: a mismatch negativity study.
CONCLUSION: LIs of MMN amplitudes a approximately 2 weeks post left-hemisphere stroke serve as more sensitive predictors of language outcome, among which the LI over the perisylvian area exhibits the best predictive value. PMID: 31567479 [PubMed - as supplied by publisher]

Clinical and Radiological Difficulties to Detect Isolated MCA Dissection before Intravenous tPA Therapy
A 64-year-old woman was admitted to our hospital 48 minutes after sudden onset of dysphasia and right hemiplegia. Head computed tomography revealed small infarcts in the left putamen and 4-dimensional computed tomography angiography depicted high-degree stenosis in the left middle cerebral artery and delayed filling of the contrast media in the left middle cerebral artery territory. The patient underwent intravenous tissue plasminogen activator treatment. On day 5 of hospitalization, the patient underwent conventional cerebral angiography, revealing internal carotid artery to middle cerebral artery dissection.

Lesion-aphasia discordance in acute stroke among Bengali-speaking patients: Frequency, pattern, and effect on aphasia recovery
ConclusionLesion-aphasia discordance following acute stroke is not uncommon among Bengali-speaking subjects. In the discordant group, preponderance towards non-fluent aphasia was observed. Discordance occurred more frequently after hemorrhagic stroke. Subjects with lesion-discordant aphasia presented better recovery during early post-stroke phase.

Anterior Choroidal Artery Infarction Evaluated with 123I-Imp Single-Photon Emission Computed Tomography and 7 Tesla Magnetic Resonance Imaging
Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis.
