Background Interstitial lung disease (ILD) is a common complication of Systemic Sclerosis (SSc) and frequently may be cause of death of patients. High resolution computed tomography (HRCT) is the reference imaging tool for the assessment of ILD; however, its use may be limited for both ionising radiation and costs. In this way, pulmonary ultrasound...

Summary: Diseases of the peripheral nerves are common in the field of neurology, they are not infrequent to occur in association with orthopedic or rheumatic diseases, sometimes they can be confused or categorized as primary diseases of the musculoskeletal system. Ultrasound is a valuable and inexpensive tool to characterize the neural fibers and i...

Objective: To characterize the ultrasound (US) pattern of joint involvement in primary Sjögren's syndrome (pSS). Methods: Seventeen patients with pSS, 18 with secondary Sjögren's syndrome (sSS), and 17 healthy controls underwent US examinations of various articular regions. Synovitis (synovial hypertrophy/joint effusion), power Doppler (PD) sign...

Introduction: Synovial cyst is composed by a fibrous wall; lining by a thin layer of synovial cells containing synovial fluid, the prototype of these, in the knee is the Baker's cyst, which is located abnormally in the gastrocnemius semimembranous bursa. Baker's cyst prevalence ranges from 5 - 38%. Clinical diagnosis is supported by the presence o...

In this study, we aimed to investigate ultrasonographic (US) changes suggestive of gouty arthritis in the hyaline cartilage, joints and tendons from asymptomatic individuals with hyperuricemia. We conducted a cross-sectional, controlled study including US examinations of the knees and first metatarsal-phalangeal joints (first MTPJs), as well as of...

The spondyloarthropathies (SpA) are a group of interrelated and het-erogeneous diseases that primarily affect the entheses and synovial membrane of peripheral joints, the sacroiliac and vertebral column. May or may not be accompanied by extra-articular manifestations, with significant familial aggregation and association with HLA B27 antigen. There...

PURPOSE/AIM - To familiarized with nerve ultrasound assesment in musculoeskeletal evaluation - MRI correlation for better understanding of findings - Indications and contraindications of nerve ultrasound CONTENT ORGANIZATION - Anatomy review - Systematic approach and nerve characteristics - neck - upper extremity - lower extremity - Normal findin...

PURPOSE/AIM The aim of this exhibit is to describe common and uncommon imaging findings with Magnetic Resonance Enterography (MRE), abdomen computed tomography (CT), and barium studies of patients with intestinal tuberculosis (IT). CONTENT ORGANIZATION 1. Brief review of etiology, pathology, clinical course, and management of intestinal tuberculos...
