A localized arteriovenous malformation of the bladder is extremely rare. When arteriovenous malformation is suspected, an angiogram and pelvic computed tomography or magnetic resonance imaging is essential to delineate the extent of the disease and to appropriately plan therapy. We report a case of arteriovenous malformation of the urinary bladder in a 39 years old female who presented with recurrent attacks of gross hematuria. The lesion was evident on ultrasonography and CT scan and the diagnosis was confirmed on cystoscopy. The lesion was successfully treated by dual transcatheter arterial and venous embolization.

Introduction A 55 year old female with a past medical history significant for seizure, spina bifida status post ventriculoperitoneal (VP) shunt, and chronic respiratory failure with chronic tracheostomy on home trilogy ventilator presented with seizurelike activity and dysphagia. Patient was not on any antiepileptic drugs and she did not have seizure for a few years. Electroencephalography revealed no electrographic seizures or interictal epileptiform activity. Head CT showed significant dilatation of the lateral and third ventricles (FIGURES 1 and 2). Further history Xiaoliang (Shawn) Qiu & Fuad M Zeid

Introduction The mental foramen (MF) is a topographic anatomical landmark for mental anesthesia in dentistry. It has an oval or circular shape and is located on the outer surface of the mandible on both sides off the midline at a one quarter distance between the profile projections of the mandibular symphysis and posterior edge of the ramus [1]. MF is the output point of the canal of the same name containing a neurovascular bundle.

We analyze the performance of a Weighted Least Squares (WLS) GRAPPA calibration for improving the g-factor of GRAPPA reconstruction from low Signal-to-Noise-Ratio (SNR) acquisition. Our method is particularly useful when the SNR degradation is influenced by noise correlation across channels. When applied with regularization, this form of GRAPPA reconstruction is found to be superior compared to other recent variants of GRAPPA such as coefficient penalized GRAPPA. We demonstrate this feature quantitatively using GRAPPA derived g-factors.

Malignant pleural mesothelioma (MPM) is the most frequent primary neoplasm of the pleura. Although asbestos use has been banned in many developed countries, the incidence has been significantly increasing because of widespread occupational exposure over the last decades. Since the latency between first asbestos exposure and tumor development is around 40 years, the peak age incidence ranges from the sixth to the eighth decades and, since most asbestos exposure is work-related, the incidence is markedly higher in men than in women, the annual rates being 15 cases per million and 3 cases per million, respectively, in the United States. Most commonly, MPM originates within the parietal pleura located in the lower hemithorax and the costophrenic angle. It spreads locally to the ipsilateral visceral pleura and relentlessly invades adjacent structures, such as the lung, chest wall, diaphragm, pericardium, and mediastinum. Disease may invade the contralateral pleural space and the peritoneum. Lymphatic and hematogenous metastases tend to occur late in natural history but are present at autopsy in approximately 50% of patients with MPM. The clinical manifestations are nonspecific and many patients present with advanced-stage disease and comorbidities. The patient prognosis is poor, with a median survival after diagnosis of approximately 12 months. The diagnosis of this neoplasm is often made at a late stage and the prognosis is still very poor with a median survival from diagnosis of under a year with supportive care alone. Achieving early diagnosis and helping to select the most appropriate treatment option in MPM patients is mandatory. In this pictorial essay, the spectrum of imaging features of MPM at Chest Radiography (CXR), Computed Tomography (CT), Magnetic Resonance (MR), Positron Emission Tomography (PET), integrated PET/CT, and Ultrasonography (US) are discussed, and a diagnostic pathway in patients with undiagnosed pleural effusion is proposed.

A coronary artery anomaly is a congenital defect of one or more coronary arteries of the heart in terms of origin, number, course and termination of the artery. A 69 year old lady with angina on exertion admitted to our hospital after detection ischemia of inferior segment of the left ventricle on imaging. Coronary angiography showed an isolated single coronary artery with an aberrant right coronary artery originating from distal left circumflex artery. Here we would like to attract attention to coronary abnormalies by presenting this case.

We propose a novel flow-diverter stent, “valve hybrid fractal stent” to treat the cerebral aneurysm what is one of a cerebrovascular disease. The stent has a valve part to path through a coil. The valve has fractal-pattern structures. So, the blood speed flowing into cerebral aneurysm is reduced. We had experiment of Particle Image Velocimetry (PIV) for evaluation of the inflow of cerebral aneurysm. By the experiment result, we visualized the stream line by using the cerebral aneurysm model. We succeeded in a speed reduction of the inflow with our valve hybrid fractal stent.
