MR Imaging of the Hip: Infectious and Inflammatory Conditions.

MR imaging is a useful tool in establishing the diagnosis of inflammation and/or infection in the hip joint and adjacent tissues, and in determining the extent of disease. In conjunction with clinical factors, MR imaging findings can help to narrow the differential diagnosis in individual cases and can guide decisions regarding biopsies, aspirations, or additional imaging.

Design and Validation of a Peer-Teacher-Based Musculoskeletal Ultrasound Curriculum.

Rationale And Objectives: To design and validate a peer-teacher based musculoskeletal ultrasound curriculum for radiology residents.

Materials And Methods: A musculoskeletal ultrasound curriculum with hands-on scanning workshops was designed for radiology residents. Prior to the workshops, several residents received 3 hours of hands-on training in ultrasound scanning technique which was overseen by an attending musculoskeletal radiologist; these "peer teachers" then led small-group hands-on scanning during the workshops.

Characterization and Surgical Management of Metastatic Disease of the Tibia.

Osseous metastases are common in advanced cancer stages. The tibia is the appendicular skeleton bone affected third most often. However, tibial metastases are not well described.

Survey of current trends in postgraduate musculoskeletal ultrasound education in the United States.

Objective: To determine current trends in postgraduate musculoskeletal ultrasound education across various medical specialties in the United States.

Materials And Methods: A survey regarding musculoskeletal ultrasound education was sent to all program directors for diagnostic radiology and physical medicine rehabilitation residency programs, as well as adult rheumatology and sports medicine fellowship programs in the United States. The survey, sent in July 2015, queried the presence of formal musculoskeletal ultrasound training, the components of such training and case volume for trainees.

Imaging appearances of musculoskeletal developmental variants in the pediatric population.

Variations in musculoskeletal development in children are commonly encountered. These variants often have a confusing appearance on imaging and may simulate pathologic conditions. However, in many instances, these normal variants have certain features that allow for confident determination of the benign nature of these entities.

MRI findings in pediatric patients with scurvy.

In modern times scurvy is a rarely encountered disease caused by ascorbic acid (vitamin C) deficiency. However, sporadic cases of scurvy persist, particularly within the pediatric population. Recent individual case reports highlight an increased incidence of scurvy among patients with autism or developmental delay, with isolated case reports detailing the magnetic resonance imaging (MRI) findings of scurvy in these pediatric populations.

Aggressively recurrent infantile myofibroma of the axilla and shoulder girdle.

Infantile myofibroma is the most common fibrous tumor of infancy, typically affecting neonates and children under 2 years of age. Though the multicentric variant portends a grave prognosis, solitary lesions have an excellent prognosis and frequently undergo spontaneous regression. Surgical excision of solitary lesions is usually curative.

Pain in the butt: spectrum of gluteal region abnormalities in children.

Objective: The purpose of this study was to illustrate the spectrum of solitary gluteal lesions in children. The distinctive anatomic and radiologic features are discussed.

Conclusion: Pathologic entities in the gluteal region reflect the diversity of tissue types present.

Cryptococcal pyarthrosis and sarcoidosis.

Cryptococcus neoformans is an infrequent cause of septic arthritis. Cryptococcal infections have been linked to sarcoidosis because of both inherent immunologic consequences of the disease and its typical immune modulating treatments. Cryptococcal infections should be suspected in patients with underlying immune deficiencies, and a high degree of vigilance should be exercised to avoid misdiagnosis, dissemination of infection, and meningitis.

Spontaneous hemorrhage simulating rapid growth of a benign subperiosteal plexiform neurofibroma.

Spontaneous subperiosteal hemorrhage is a rare complication of von Recklinghausen's disease. There are few reports describing the MR imaging characteristics of this entity. Our case is unique among these as an underlying plexiform neurofibroma was visualized by MR imaging.
