Item A Case of Mediastinal Mesenchymal Tumor Resembling Hemopericardium(2021) Acibuca, Aynur; Yilmaz, Mustafa; Karadeli, Elif; Canpolat, Emine Tuba; Erol, Tansel; 34404995Mediastinal neoplasms are rare in the elderly, and clinical suspicion is the first and most important step of differential diagnosis. Mediastinal tumors can be misdiagnosed because their symptoms or signs can overlap with cardiovascular diseases, which have a higher prevalence among the older population. The diagnostic process should be managed with multimodality imaging and clinical judgement. Here, the case of a 74-year-old male patient, who presented with shortness of breath, is examined. A chest X-ray revealed an increased cardiothoracic ratio, and he was diagnosed with hemopericardium following an emergent chest computed tomography. In the echocardiography, it was suspected that a hyperechogenic area adjacent to the heart might be due to a mass, and further examinations confirmed a mediastinal neoplasm. A surgical biopsy was performed, and it was determined to be a mesenchymal tumor. To conclude, clinicians should keep in mind the possibility of paracardiac neoplasm in the elderly, as well as in other age groups, when encountering mediastinal widening so that the patient can be protected from unnecessary interventions such as pericardiocentesis.Item Prognostic values of ADC(mean) and SUVmax of the primary tumour in cervical cancer patients treated with definitive chemoradiotherapy(2019) Yildirim, Berna Akkus; Onal, Cem; Erbay, Gurcan; Guler, Ozan Cem; Karadeli, Elif; Reyhan, Mehmet; Koc, Zafer; 0000-0002-2742-9021; 0000-0003-0987-1980; 30354907; D-5195-2014; S-8384-2016We analysed the correlation of F-18-fluorodeoxyglucose uptake into primary tumours using the maximum standardised uptake value (SUVmax) and the mean apparent diffusion coefficient (ADC(mean)) values in magnetic resonance imaging (MRI) with the clinical and pathological factors in patients with cervical cancer who were treated with concurrent chemoradiotherapy. The patients were stratified according to the primary tumour pre-treatment ADC(mean) and SUVmax cut-off values. There were significant correlations between the SUVmax of the primary tumour and tumour size, and the treatment response. The correlation between the ADC(mean) and FIGO stage, tumour size, and the lymph node metastasis was significant. The SUVmax was significantly and inversely correlated with the ADC(mean) for cervical cancer (r = -0.44, p <.001). In the multivariate analysis, the primary tumour ADC(mean), treatment response and the lymph node metastasis emerged as significant independent predictors of both OS and DFS, and of the primary tumour SUVmax for DFS. Tumour size has a borderline significance for OS. High SUVmax and low ADC(mean) of the primary tumour are important predictive factors for identifying high-risk patients with cervical cancer who are treated with definitive chemoradiotherapy. These results point to a future role for the diffusion-weighted MRI and for F-18-fluorodeoxyglucose positron emission tomography, not only in the staging of cervical cancer but as an aid in the selection of an adjuvant treatment regimen after chemoradiotherapy for individual patients.
