To assess intra-bursal corticosteroid injections (ICSI) efficacy and duration of action in the management of greater trochanteric pain syndrome (GTPS). The secondary aim was to identify patient and ultrasound (US) features predictive of treatment response. ⋯ ICSIs confer a benefit in pain reduction to a large proportion of patients in the short term, but this may not be reduced by a clinically significant amount. This small effect size and lack of predictive imaging features suggests initial management including subsequent steroid injection could be provided without imaging guidance in the majority of cases.
-
To investigate the clinical and image features of thymic neuroendocrine tumours (NETs), and characterise the radiological patterns of recurrence and metastasis on serial imaging studies. ⋯ Thymic NETs presented as a large, lobulate, heterogeneous mass with an infiltrative nature. Metastasis and recurrence were frequent, most commonly involving thoracic lymph nodes, while extra-thoracic metastasis to bones and abdominal lymph nodes were also noted.
-
To evaluate progressive changes in quantitative CT features of the non-solid component of ground-glass nodules (GGNs) from baseline to follow-up to differentiate invasive (minimally invasive adenocarcinoma [MIA] and invasive adenocarcinoma [IA]) GGNs from benign or pre-invasive (adenocarcinoma in situ [AIS]) lesions. ⋯ In GGN follow-up, the diameter of benign and AIS, and invasive GGNs significantly increased. Additional analysis of mean density and density deviation in the non-solid component may help to identify invasive GGNs.
