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...

Association of Cancer Cell Type and Extracellular Vesicles With Coagulopathy in Patients With Lung Cancer and Stroke Brief Report
Conclusions—Our findings indicate that cancer cell type is associated with circulating EV levels and coagulopathy in patients with lung cancer and stroke.

Recurrent Stroke Due to Metastatic Pulmonary Tumor Emboli as an Important Clinical Entity
We present an autopsy case of repetitive stroke due to tumor emboli, indistinguishable from thromboembolism with a hypercoagulable state in its clinical course. A 72-year-old man diagnosed with stage IVA oropharyngeal squamous cell carcinoma received chemoradiotherapy. Follow-up imaging revealed mediastinal lymph nodes and pulmonary metastasis. One year later, the patient experienced right arm weakness, and brain magnetic resonance imaging showed acute ischemic lesions in multiple vascular territories.

Teaching NeuroImages: Radiation-associated symptomatic carotid artery disease with ipsilateral radiodermatitis
A 68-year-old man with a history of squamous cell carcinoma of the tongue treated with external beam radiation therapy in 2007 presented in 2013 with acute onset expressive aphasia and right lower facial weakness. MRI confirmed an acute infarct in the left frontal cortex. CT angiography revealed occlusion vs critical stenosis of the left internal carotid artery, new from 2007. Examination of the patient's neck revealed ipsilateral radiodermatitis (figure). Therapeutic neck irradiation has been associated with accelerated atheromatous disease, carotid artery stenosis, and increased risk of stroke.1,2 Ipsilateral radiodermat...

A Case Series Of Non-Bacterial Thrombotic Endocarditis Associated With Gynecological Malignancies (P6.248)
Conclusions:NBTE is an important ischemic stroke mechanism. We have reported three cases where the underlying malignancy was gynecological (endometrial, ovarian, and cervical). In the first two cases, the malignancy was discovered during the investigations for the stroke mechanism, while the third had a known underlying malignancy. This series highlights the need to consider gynecological malignancies as an underlying cause of stroke in young women; and that the ischemic event can occur prior to the malignancy diagnosis.Disclosure: Dr. Schabas has nothing to disclose. Dr.Teal has received personal compensation for activiti...
