Iatrogenic Aortic Root Injury from Coronary Interventions: Early and Follow-up CT Imaging Findings

AbstractBreast tuberculosis is a rare form of extrapulmonary tuberculosis which tends to affect females of reproductive age, and is much rarer in males, postmenopausal women, and pre-pubescent girls. It is difficult to diagnose because it can mimic benign conditions such as a fibroadenoma, as well as malignant diseases like a carcinoma. It is also particularly difficult to distinguish breast tuberculosis from granulomatous mastitis, so other possible diagnoses should be ruled out first. The diagnosis of breast tuberculosis has three essential pillars: clinical examination, radiological evaluations, and histopathological sampling. Radiological evaluations are not only critical in diagnosis but are also important in the planning of the treatment and during the follow-up. This paper aims to review the imaging findings and the differential diagnosis of breast tuberculosis.

Reversible Encephalopathy

Neurological conditions are being more recognised in patients with COVID-19, with encephalopathy being the most prevalent problem. Posterior reversible encephalopathy is suspected to occur due to elevated blood pressure and overproduction of inflammatory markers, both of which have been reported in the setting of COVID-19 infection. Encephalopathy was the main presentation in this case, without respiratory dysfunction initially, and with imaging findings indicative of posterior reversible encephalopathy syndrome as an aetiology. Follow-up imaging showed resolution of the abnormal results with mental status returning to baseline upon discharge.

Abstract Funding Acknowledgements Type of funding sources: None. Background Myocardial inflammation may occur in the context of a multisystem disease such as sarcoidosis, adversely affecting prognosis. A definitive diagnosis of cardiac sarcoidosis (CS) is essential to implementing life-saving treatment but this is complicated by the invasive nature of endomyocardial biopsy (EMB) and its low accuracy. Positron emission tomography (PET) assists in diagnosis, which relies on visual interpretation of myocardial F-18 FDG uptake. The value of quantitative analysis and its application to clinical practice remain uncertain. Purpose To investigate the power of quantitative F-18 FDG PET-CT imaging analysis for detecting CS in patients with suspected disease. Methods All patients underwent F-18 FDG PET-CT after a 24-hour low-carbohydrate diet and 15-hour fasting as part of their diagnostic work-up for suspected cardiac inflammation. Cardiovascular magnetic resonance acted as gatekeeper to PET-CT in 8 of every 10 scans. Myocardial F-18 FDG uptake was assessed qualitatively and quantitatively using both manually drawn regions of interest and automatic polar maps to measure global and segmental standardised F-18 FDG uptake values (SUV). The coefficient of variation (CoV) was calculated to determine uptake heterogeneity. To confirm diagnosis, follow-up data regarding disease progression, further testing and treatment were collected. To allow for sufficient follow-up time, the first 40 consecutive patients from a prospective registry (n= 214; Sep 2017-Jun 2020) were included. Results A comprehensive clinical picture was obtained successfully in 37 patients (median [IQR], 17 [13.5] months) and a final diagnosis of CS reached in 7 (disease prevalence, 19%). EMB was performed in 2 patients only while 3 underwent PPM/ICD implantation. Significant predictors of CS were fulfilment of Japanese Ministry of Health and Welfare criteria (Wald, 6.44; p = 0.01) and left ventricular dysfunction (Wald 6.72; p = 0.01). Qualitative F-18 FDG PET-CT had a high negative (95%) but low positive (45%) predictive value for CS (sensitivity, 83%; specificity, 77%). F-18 FDG SUV CoV was the strongest imaging predictor (Wald, 6.77; p = 0.009) and was significantly higher in CS than non-CS (CoV median [quartiles], 0.26 [0.21, 0.36] and 0.12 [0.11, 0.14] respectively; p = 0.004). As per ROC curve analysis (AUC, 0.84), a CoV threshold of 0.20 was highly specific (93%) and sensitive (86%) for CS. Conclusion In a referring population with a low prevalence of cardiac sarcoidosis, F-18 FDG PET-CT imaging is sensitive for the detection of myocardial inflammation with active disease unlikely in patients with a negative scan. Quantitative evaluation of metabolic heterogeneity within the myocardium provides a strong, independent marker of active disease and should be considered alongside visual assessment.

Abstract Objectives Muscle involvement in Behçet’s disease (BD) is rare, and several cases have been reported in the literature. Therefore, this study aimed to describe the clinical, laboratory and imaging findings in adult patients presenting with BD-associated myositis before the diagnosis of BD. Methods We retrospectively screened patients who visited a locomotive medicine clinic presenting with myalgia, local swelling, or tenderness of extremities without an established diagnosis of BD. We enrolled patients whose pain in the extremities was proven to be suggestive of focal vasculitic myositis and who were eventually diagnosed as having BD at the initial visit or during follow-up. We thoroughly reviewed the clinical, histological and imaging findings and treatment outcomes in patients who presented with focal vasculitic myositis as the primary manifestation of BD. Results Ten adult patients with focal vasculitic myositis as the primary manifestation of BD were enrolled. The lower and upper extremities were affected in eight and two patients, respectively. The affected lower extremities were the calf (n = 6) and thigh muscles (n = 2). The common findings of MRI included high signal intensity of the affected muscles and intermuscular fascia on fat-suppressed images, suggestive of myofascitis and oedematous changes in the subcutaneous layer. The results of skin or muscle biopsy were suggestive of vasculitis. All the patients were pain-free at the short-term follow-up (1–3 weeks) after oral steroid therapy. Conclusion Focal vasculitic myositis can be a primary manifestation of BD warranting medical attention. BD-associated myositis responds well to oral steroid therapy.
