High-frequency ultrasonography for subungual glomus tumor evaluation – imaging findings
ConclusionThe study concludes that ultrasound evaluation is highly useful for diagnosing glomus tumors, especially when multiple findings, such as bone remodeling, hypervascularization, and the stalk sign, are present. This method allows for accurate diagnosis, observation of periungual structures, and proper surgical planning, ultimately reducing recurrence rates. (Source: Skeletal Radiology)

Isolated distal grade III lateral collateral ligament injury: what is the real clinical impact in professional athletes?
We report 3 cases of professional soccer players with isolated distal lateral collateral ligament III grade injury, confirmed by MRI studies. After undergoing MRI examinations, all three players resumed competitive activity without resting and experienced no consequences regarding joint stability. We assessed the significance of the lateral collateral ligament in providing lateral stabilization to the knee joint in professional footballers with clinical tears of the lateral collateral ligament. The other structures of posterolateral area that remain intact contribute to joint stability, and the lateral collateral ligament ...

Epithelioid angiosarcoma of the calf: a case report of an atypical imaging appearance
AbstractAngiosarcoma is an uncommon cause of soft tissue malignancy, accounting for approximately 2% of all soft tissue sarcomas. Of these, epithelioid angiosarcoma represents a morphologic subtype, where the malignant endothelial cells demonstrate a predominantly or exclusively epithelioid appearance. Overall, epithelioid angiosarcoma shares similar imaging characteristics to conventional angiosarcoma including a T1 hypointense to isointense and T2 hyperintense mass, which demonstrates avid enhancement, serpentine feeding vessels, and overlying skin thickening on MRI. The case herein describes a case of epithelioid angios...

Whole-body MRI for the investigation of joint involvement in inflammatory arthritis
ConclusionThis study has developed a whole-body MRI joint imaging protocol that is clinically feasible and shows good differentiation of joint pathology between healthy controls, patients with rheumatoid arthritis and patients with other forms of arthritis. (Source: Skeletal Radiology)

Revision of the 1994 World Health Organization T-score definition of osteoporosis for use in older East Asian women and men to reconcile it with their lifetime risk of fragility fracture
AbstractThe 1994 WHO criterion of a T-score ≤ -2.5 for densitometric osteoporosis was chosen because it results in a prevalence commensurate with the observed lifetime risk of fragility fractures in Caucasian women aged ≥ 50 years. Due to the much lower risk of fragility fracture among East Asians, the application of the conventi onal WHO criterion to East Asians leads to an over inflated prevalence of osteoporosis, particularly for spine osteoporosis. According to statistical modeling and when a local BMD reference is used, we tentatively recommend the cutpoint values for T-score of femoral neck, total hip, a...

Experience with ultrasound neurography for postoperative evaluation of targeted muscle reinnervation
This report will illustrate the potential utility of ultrasound neurography to accurately differentiate TMR surgical outcomes in two patients that received upper extremity amputation and subsequent reconstruction with TMR. Ultrasound evaluation of TMR sites in patient 1 confirmed successful reinnervation, evident by nerve fascicle continuity and eventual integration of the transferred nerve into the target muscle. Conversely, the ultrasound of patient 2 showed discontinuity of the nerve fascicles, neuroma formation, and muscle atrophy in all three sites of nerve transfer, suggesting an unsuccessful procedure and poor funct...
