#1
Zerwa Farooq, Brooke Devenney-Cakir
Viridans group streptococcus is an infrequent cause of osteomyelitis that is found in association with infective endocarditis. Only a few studies report viridans osteomyelitis in the absence of endocarditis. Vertebral pyogenic osteomyelitis can sometimes be complicated by psoas or paraspinal abscesses. These intra-abdominal and/or pelvic collections can very rarely result in venous thrombosis. A paraspinal abscess resulting in inferior vena cava (IVC) thrombosis has only been reported once in the literature...

BACKGROUND: Percutaneous access to the vertebral bodies is commonly done via the transpedicular approach for both diagnoses and treatment of spinal pathology. While this approach is effective in most cases, it is difficult in certain situations such as a patient with obstructing hardware from prior surgery. OBJECTIVES: To investigate and illustrate an alternative to the typical percutaneous access to the vertebral body via an extrapedicular approach and to determine the complications associated with this approach...

The purpose of this work was to systematically assess the impact of the b-value on texture analysis in MR diffusion-weighted imaging (DWI) of the abdomen. In eight healthy male volunteers, echo-planar DWI sequences at 16 b-values ranging between 0 and 1000 s/mm(2) were acquired at 3 T. Three different apparent diffusion coefficient (ADC) maps were computed (0, 750/100, 390, 750 s/mm(2) /all b-values). Texture analysis of rectangular regions of interest in the liver, kidney, spleen, pancreas, paraspinal muscle and subcutaneous fat was performed on DW images and the ADC maps, applying 19 features computed from the histogram, grey-level co-occurrence matrix (GLCM) and grey-level run-length matrix (GLRLM)...

BACKGROUND: The association between body composition (e.g. sarcopenia or visceral obesity) and treatment outcomes, such as survival, using single-slice computed tomography (CT)-based measurements has recently been studied in various patient groups. These studies have been conducted with different software programmes, each with their specific characteristics, of which the inter-observer, intra-observer, and inter-software correlation are unknown. Therefore, a comparative study was performed...

We report 6 cases of a novel syndrome of acute, exertional low back pain (LBP) in football players, 5 in college and one in the National Football League (NFL). All 6 are African-Americans with sickle cell trait (SCT). The acute LBP is severe and can be disabling, and the condition can be confused with muscle strain, discogenic pain, stress fracture, or other problems in athletes. Our evidence shows that this syndrome is caused by lumbar paraspinal myonecrosis (LPSMN), which likely often contributes to the lumbar paraspinal compartment syndrome...

Angiomatosis is a nonneoplastic proliferative vascular lesion, which occurs mostly in diverse soft tissues. We observed a rare case of mediastinal angiomatosis with intraspinal invasion that mimicked a dumbbell tumor in a 63-year-old man with a history of prostate adenocarcinoma. A roentgenogram of the chest showed that the patient had left pleural effusion and a left paraspinal mass, computed tomography disclosed a low-density fusiform lesion over the left paraspinal region, and magnetic resonance imaging confirmed a large posterior mediastinal tumor with T4 intraspinal invasion...
