“…(2) Haemangioma may appear with slightly higher signal intensity than muscle in T1WI. It may show a worm-like or punctuate hypointensity without feather-like changes in T2WI [38, 39]. (3) Synovial sarcoma occurs in the large joints and shows heterogeneous signal intensity with mainly an iso-intensity.…”

Aim of the studyTo investigate the magnetic resonance imaging (MRI) features of skeletal muscle metastases (SMM).Material and methodsThe records of 31 patients with proven SMM were retrospectively reviewed. Clinical history, type of primary malignancy, location of metastases, and MRI features of SMM were evaluated. Based on MRI findings, SMM were divided into three MRI types. The correlation between MRI types with ages and pathology category, between MRI types of SMM and ages, as well as MRI types of SMM and pathology category were analysed with Spearman's rho.ResultsThe most common primary tumour was genital tumour (25.8%) and bronchial carcinoma (19.4%), and the most common cell type was adenocarcinoma (58.1%). SMM were located in the iliopsoas muscle (26.3%), paravertebral muscles (21.1%), and upper extremity muscles (18.4%). MRI features: (1) Type-I localised lesions (12.90%), round-like mass limited to local regions with heterogeneous iso-signal intensity in T1WI and heterogeneous hyper-intensity in T2WI; (2) Type-II diffuse lesions without bone destruction (35.48%), abnormal diffuse swelling of the muscle with irregular boundaries and slightly hypo- to iso-intensity in T1WI and hyper-intensity in T2WI; and (3) Type-III diffuse lesions with bone destruction (51.61%), distinct irregular lump with iso-intensity in T1WI and heterogeneous hyper-intensity in T2WI with adjacent bone invasion. There was positive correlation between MRI types and ages (r = 0.431, p < 0.05). There were no significant differences of MRI types with pathology category (p > 0.05).ConclusionsSMM features on MRI can be broadly used to classify lesions, which is beneficial for SMM diagnosis.

“…The sternoclavicular joint is an uncommon site for septic arthritis, accounting for only 1% of all joint infections, although it accounts for 17% of septic joint infections in intravenous‐drug abusers . US examination reveals inflammation of the adjacent soft tissue, joint effusion, and sometimes periarticular abscess formation (Figure ). Osteomyelitis of the chest wall is an uncommon but potentially life‐threatening sequela …”
