Osteoid osteoma of the hip: imaging features
AbstractOsteoid osteoma (OO), a small bone tumor relatively common in young subjects, frequently involves the hip. In addition to typical findings, we emphasize unsuspected clinical and imaging features including painless OO causing limping gait, non-visibility of totally mineralized nidus, absence of hyperostosis or adjacent edema, and recurrence at distance from the initial location. We also discuss the option of medical treatment for some cases of deep hip locations. (Source: Skeletal Radiology)

A comprehensive review of the normal, abnormal, and post-operative MRI appearance of the distal biceps brachii
AbstractThe biceps brachii myotendinous unit is a common source of shoulder, arm, and elbow pain. Its complex anatomy can present a challenge when interpreting MR images. We discuss the clinical and imaging presentations of injury related to the proximal biceps brachii separately in another manuscript. The purpose of this manuscript is to review the distal biceps anatomy along with pathology and post-operative appearance as seen on MRI. (Source: Skeletal Radiology)

Concomitant calciphylaxis and COVID-19 associated thrombotic retiform purpura
AbstractWhile initial reports regarding coronavirus disease 2019 (COVID-19) focused on its pulmonary manifestations, more recent literature describes multisystem abnormalities related to its associated microvascular angiopathy. Calciphylaxis is a rare systemic condition characterized by tissue necrosis in the setting of systemic microvascular calcifications. Both COVID-19 and calciphylaxis are procoagulant diagnoses associated with vascular-mediated cutaneous findings. To our knowledge, this is the first report to document the coexistence of COVID-19 associated retiform thrombotic purpura and calciphylaxis in a single pati...

Soft tissue sarcoma: can dynamic contrast-enhanced (DCE) MRI be used to predict the histological grade?
ConclusionHigh-grade STSs were usually larger than low-grade STSs, had unclear boundaries, a heterogeneous signal intensity on T2-weighted image (T2WI), and extensive necrosis. On DCE-MRI, iAUC, TTP,Ktrans, andKep could differentiate between high-grade and low-grade STSs. The combination of iAUC, TTP, andKtrans had a high diagnostic performance for differentiating between STS histological grades. (Source: Skeletal Radiology)

Society of skeletal radiology member utilization and performance of whole-body MRI in adults
ConclusionThere is variation in who is responsible for the protocol and interpretation of WBMRI, as well as how the exam is performed and how the exam is coded, which raise barriers to broad implementation. Recent WBMRI guidelines for multiple myeloma and prostate cancer can mitigate many of these barriers, but they do not address the coding and reimbursement challenges. Collaborative multi-society development of a new CPT ® code for WBMRI may be a worthwhile endeavor. (Source: Skeletal Radiology)

Imaging of shoulder instability
AbstractThe shoulder enjoys the widest range of motion of all the joints in the human body, therefore requires a delicate balance between stability and motility. The glenohumeral joint is inclined to fall into two main instability categories: macro and micro. Macroinstability can be traumatic or atraumatic, with anterior or posterior dislocation of the humeral head. Microinstability falls within the broader section of acquired instability in overstressed shoulder caused by repeated joint stress. Anterior traumatic instability is the most frequent entity and a relatively common injury in young and athletic population.  ...

We report a case of a slowly growing buttock mass after gluteal augmentation with autologous fat transfer 1  year after surgery. The potential diagnostic imaging pitfalls and characteristics on ultrasound and contrast-enhanced MRI are discussed. Multiplicity of fat-containing lesions depicted on large field-of-view images and granulated appearance of the intralesional fat on MRI should allow the radiolog ist to recognize the appearance of failed fat graft incorporation that can present as a slowly growing encapsulated collection with layered fat and fluid contents.

We tested the correlation of psoas muscle mass and quality estimation at L3 with that of hip muscles, which could be opportunistically used in patients undergoing hip surgery.Materials and methodsUnenhanced abdominal CT performed in 50 patients (29 males, mean/median age 69/72  years) were reviewed.

The G2 research R.I.P. fragmenting bullet —radiographic features of a recently encountered projectile
AbstractGunshot wounds (GSWs) are an important cause of disability and death in the USA. Although radiography is limited in its ability to detect bullet types, a projectile introduced during the last decade, the R.I.P. bullet by G2 Research, consists of a base slug connected to 6 to 8 sharp trocars designed to diverge within soft tissue following impact, resulting in what we believe to be a unique imaging appearance that can be confusing to those not familiar with this particular projectile. Furthermore, this bullet is 100% copper, which may allow for safe imaging with magnetic resonance imaging if correctly identified pri...
