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...

One-year prognosis of non-traumatic cortical subarachnoid haemorrhage: a prospective series of 34 patients
ConclusionsThe most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment.ResumenIntroducciónLas hemorragias subaracnoideas corticales (HSAc) tienen numerosas etiologías. No hay estudios prospectivos que indiquen su evolución a largo plazo. El objetivo de este trabajo es describir las características clínicas y etiológ...

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Cerebral air embolism during CT-guided lung biopsy
A patient with cirrhosis and hepatocellular carcinoma, on the waiting list for liver transplantation, presented with lung nodule during initial evaluation. A CT-guided core needle lung biopsy under general anaesthesia was performed. Pneumothorax (figure 1) and a large amount of gas within the left ventricle (figure 2) were identified during the procedure. Neurological focal signs (drowsiness, conjugate eye deviation and right hemiparesis) were observed in the anaesthesia-recovery period. A brain CT scan was immediately obtained, showing cerebral air embolism (figure 3). Initial resuscitation and hyperbaric oxygen therapy w...

Summary: International Kidney Cancer Symposium
Conclusions:  Ideal ischemia time is 20-25 minutes or less improves short and long term renal function.  >25 minutes carried 5 year risk of new onset stage 4 CKD No differences on GFR for cold vs. warm ischemia times Preoperative GFR and the percent of kidney preserved was a better predictor of post op GFR.  No ischemia preserves renal function better than warm. Longer cold ischemia times were equivalent to shorter warm ischemia times. Quality and quantity of the remaining kidney is associated with ultimate renal function.

Bilateral lingual artery stenosis: A rare, late complication of chemoradiotherapy
Discussion Small vessel disease is a possible complication in patients treated by RT for head and neck cancer. Although the risk of these complications is not directly related to the total radiation dose, higher doses appear to accelerate the development of vascular lesions. Practitioners must be aware of the possibility of these complications, especially in patients surviving more than 5 years.

Multiple Thrombi in the Heart in Trousseau Syndrome Caused by Pancreatic Carcinoma
A 65-year-old woman presented to our emergency room because of sudden onset of right hemiparesis with severe fatigue. Neurological examination revealed right hemiparesis with right facial numbness and an extensor planter response on the right side.Magnetic resonance imaging with diffusion-weighted imaging revealed multiple highintensity areas in both cerebral hemispheres and the right cerebellum. A diagnosis of acute stage of multiple brain infarctions caused by emboli was made. An abdominal computed tomography showed a pancreatic tumor with multiple liver metastases.

Unusual Techniques for Preserving Surgical and Oncologic Safety in Hepatectomy of Advanced Adrenal Malignancy with Vena Cava and Liver Invasion
We report herein three cases of major hepatectomy with IVC invasion and discuss several surgical tips.Patients and MethodsFrom March 2011 to February 2014, we retrospectively reviewed three cases of adrenal malignancy with liver and IVC invasion. Based on the severity of the malignant tumor, each case illustrates a different method to address surgical complications and maintain oncologic safety. Case 1: A 34-year-old woman was diagnosed with adrenocortical tumor during medical examination. Tumor invaded the right lobe of the liver and very close to the IVC. Fortunately, there was little thrombosis inside the IVC; we perfor...

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...

Lynch syndrome-associated repeated stroke with MLH1 frame-shift mutation
We describe the case of a 34-year-old female patient with 50  days of sudden dizziness and left limb weakness, whose head CT scan showed large infarction in the right frontal temporal parietal lobe and basal ganglia area. Imaging examinations and pathological biopsy indicated high-grade serous carcinoma (HGSC) IIIA1 of the right ovary. In addition, a novel f rame-shift mutation in the MLH1 gene (c.1621dupG, p.A541Gfs*16) was found in the genetic panel sequence. It may render declining of MLH1 protein and also associate with the patient’s progressive clinical manifestations of multiple systems. Therefore, the timely use ...
