Karen Tran-Harding, Rashmi T Nair, Halemane Ganesh
Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is a proven, effective treatment for intermediate- and high-risk non-muscle-invasive bladder cancer. Minor side effects are common and expected but systemic effects can occur in <5% of treated patients. We present a rare case of a 49-year-old male that presented with fever and chills after 3 weeks of intravesical BCG therapy post transurethral resection of bladder tumor. New renal lesions were present on contrast-enhanced computed tomography scan which was histologically proven to be necrotizing renal granulomatosis...

Mediastinal and paracardiac lesions are usually first diagnosed on a chest radiograph or echocardiogram. Often, a computed tomography is obtained to further delineate these lesions. CT may be suboptimal for evaluation of enhancement characteristics and direct extension into the adjacent mediastinal structures. With its intrinsic superior soft-tissue characterization, magnetic resonance imaging (MRI) can better delineate these lesions, their internal tissue characteristics, and identify adhesion/invasion into adjacent structures...

Tae Hoon Ro, Lance Edmonds
Piriformis syndrome is an uncommon condition that causes significant pain in the posterior lower buttocks and leg due to entrapment of the sciatic nerve at the level of the piriformis muscle. In the typical anatomical presentation, the sciatic nerve exits directly ventral and inferior to the piriformis muscle and continues down the posterior leg. Several causes that have been linked to this condition include trauma, differences in leg length, hip arthroplasty, inflammation, neoplastic mass effect, and anatomic variations...

Segmental neurofibromatosis type 5 (NF5) is a rare form of NF, in which the cutaneous and/or neural changes are confined to one region of the body. It is often underdiagnosed or undetected due to the absence of symptoms. Inheritance of NF is different from other types of NF. Intraosseous neurofibromas are rare tumors which develop from nerves supplying the periosteum or nerves following the intraosseous course. Plexiform neurofibroma with associated intraosseous neurofibroma is extremely rare. We report a case of plexiform neurofibroma in the left axilla of a 17-year-old female with associated intraosseous neurofibroma in adjoining left humerus...

Background: Brain tumor is one of the most common tumors. A successful treatment might be achieved with an early identification. Pathological investigation as the gold standard method for tumor identification has some limitations. Noninvasive assessment of tumor specifications may be possible using perfusion-weighted magnetic resonance imaging (MRI). Cerebral blood volume (CBV) and cerebral blood flow (CBF) could be calculated based on dynamic contrast-enhanced MRI (DCE-MRI) in addition to dynamic susceptibility contrast MRI (DSC-MRI) modality...

Determining the presence and characteristics of vascular flow is an essential part of sonography interrogation. However, small vessels and low velocities are not always possible to depict with conventional color and power Doppler ultrasound. This can be frustrating, especially when the diagnosis depends mainly on the existence of vascular flow, the sonographic examination will be inconclusive, further imaging examinations will be required and diagnosis delayed. Superb microvascular imaging (SMI) is a novel vascular imaging mode, which provides visualization of low velocity and microvascular flow...
