Perivascular epithelioid cell (PEC) tumors (or PEComas) are myomelanocytic lesions defined by coexpression of melanocytic and muscle markers, suggesting dual differentiation. They are rare mesenchymal tumors and include subtypes with distinct clinical features: angiomyolipoma, lymphangioleiomyomatosis, and clear cell "sugar" tumors of the lung, pancreas and(More)
Myasthenia gravis (MG) is an autoimmune disorder often associated with thymic abnormalities. At onset, thymic lymphoid hyperplasia (TLH) and thymoma can be found in up to 65% and 15% of patients, respectively. Diagnostic imaging is crucial in this setting in order to detect the presence and type of the thymic abnormality and in the preoperative planning,(More)
The diagnosis of acute pyelonephritis (APN) requires demonstration of parenchymal involvement. When no predisposing conditions are found, non-complicated APN is suspected and CT or MRI should be performed. Diffusion-weighted (DW) MRI might be useful, quicker and cheaper than the standard gadolinium-enhanced (GE) MRI. The aim of this study is to compare(More)
This study was performed to evaluate the factors affecting the diagnostic accuracy and rate of complications of CT-guided percutaneous transthoracic needle biopsy of mediastinal masses. We reviewed 73 consecutive mediastinal biopsies in 70 patients. Final diagnoses were based on a retrospective analysis of surgical outcomes, results of repeat biopsies or(More)
This study was performed to analyse the variables affecting the diagnostic accuracy of computed tomography (CT)-guided transthoracic needle biopsy of pulmonary lesions. A retrospective study of 612 consecutive procedures with confirmed final diagnoses was undertaken. Benign and malignant needle biopsy results were compared with final outcomes to determine(More)
INTRODUCTION To prospectively evaluate the frequency and spectrum of incidental findings (IF) in a 5-year lung cancer screening program with low-dose spiral computed tomography (CT) and to estimate the additional costs of their imaging workup incurred from subsequent radiologic follow-up evaluation. MATERIALS AND METHODS A total of 519 asymptomatic(More)
Our goal was to assess the computed tomo graphy (CT) imaging findings of thymoma and to correlate these features with Masaoka staging system and prognosis. CT findings of thymoma were analysed in 58 patients who had undergone surgery between January 2002 and September 2007. All cases were classified according to the Masaoka staging system. The presence of(More)
To evaluate the usefulness of diffusion-weighted magnetic resonance for distinguishing thymomas according to WHO and Masaoka-Koga classifications and in predicting disease-free survival (DFS) by using the apparent diffusion coefficient (ADC). Forty-one patients were grouped based on WHO (low-risk vs. high-risk) and Masaoka-Koga (early vs. advanced)(More)
This review discusses the usefulness of bedside lung ultrasound in the diagnostic distinction between the various causes of acute dyspnoea in the emergency department, with special attention to the differential diagnosis of pulmonary oedema and exacerbation of chronic obstructive pulmonary disease (COPD). This is made possible by using mid- to low-end(More)
