Tumor Cells Detected in Retrieved Thrombus: A Case of Cancer-associated Stroke
Intern Med. 2021 Mar 8. doi: 10.2169/internalmedicine.6201-20. Online ahead of print.ABSTRACTA 51-year-old man with a history of renal cell carcinoma presented with sudden aphasia, right hemiparesis, and dysesthesia. MRA showed left middle cerebral artery occlusion, and he was diagnosed with acute ischemic stroke and treated with intravenous recombinant tissue plasminogen activator and endovascular thrombectomy. The pathological diagnosis of the retrieved thrombus was consistent with the already-known pathological findings of the primary renal cell carcinoma. Therefore, a diagnosis of cerebral embolism caused by tumor cell...

Acute Ischemic Stroke as a Result of Paradoxical Embolus in a Patient with Renal Cell Carcinoma, Intravenous Tumor Thrombus Extension, and Patent Foramen Ovale
Conclusions: This is the first reported case of intraoperative paradoxical embolism in the setting of RCC with cavoatrial extension and PFO. The presence of PFO may be a risk factor for severe cerebrovascular complications in the surgical management of RCC with venous involvement.

Frequency, risk factors, and impact on mortality of arterial thromboembolism in patients with cancer.
Abstract In contrast to venous thromboembolism, little is known about arterial thromboembolism in patients with cancer. The aim of this study was to quantify the risk and explore clinical risk factors of arterial thromboembolism in patients with cancer, and investigate its potential impact on mortality. Patients with newly-diagnosed cancer or progression of disease after remission were included in a prospective observational cohort study and followed for 2 years. Between October 2003 and October 2013, 1880 patients (54.3% male; median age: 61 years) were included. During a median follow-up of 723 days, 48 (2.6%) p...

Midbrain and bilateral paramedian thalamic stroke due to artery of Percheron occlusion.
CONCLUSION: Bilateral thalamic stroke due to artery of Percheron occlusion is a rare presentation of stroke, which can be overlooked in routine CT scan. If diagnosed, it requires further evaluation for stroke risk factors, especially cardiovascular disorders associated with increased embolic risk. PMID: 27154444 [PubMed - as supplied by publisher]
