“…Recent studies conducted in Brazil have highlighted the importance of imaging methods, particularly MRI, in the evaluation of tumors affecting the genitourinary system (17)(18)(19)(20)(21)(22) . The reported accuracy of mpMRI for tumor staging ranges from 75% to 94.5% (9,10,12,15) .…”

Objective: To evaluate the retrospective accuracy of the Vesical Imaging-Reporting and Data System (VI-RADS) in detecting muscle invasion in bladder cancer. Materials and Methods: We investigated patients who underwent pelvic magnetic resonance imaging and were submitted to transurethral resection of a bladder tumor between 2015 and 2018. Thirty cases were reviewed by radiologists blinded to the final clinical stage. The VI-RADS score was applied and compared with the histopathological findings in the surgical specimen. Results: Of the 30 patients with suspicious bladder lesions, 5 (16.6%) had benign histopathological findings, 17 (56.6%) had non-muscle-invasive bladder cancer, and 8 (26.6%) had muscle-invasive bladder cancer. The optimal criterion to detect muscle-invasive bladder cancer was a final VI-RADS score > 3, for which the sensitivity and specificity were 100% (95% CI: 56.0-100%) and 90.9% (95% CI: 69.3-98.4%), respectively. Conclusion: The VI-RADS appears to estimate correctly the degree of muscle invasion in suspicious bladder lesions. However, prospective studies evaluating larger samples are needed in order to validate the method.

“…Compared with CT, MRI has better contrast resolution and does not expose patients to ionizing radiation ( 5 ) . When the CT findings are inconclusive, the patient can be better evaluated by MRI, as can pediatric patients, pregnant patients, and patients for whom the use of contrast media in contraindicated ( 6 , 7 ) .…”

Common pitfalls in renal mass evaluation: a practical guide

More than half of patients over 50 years of age have had at least one focal renal lesion detected as an incidental finding during an ultrasound, computed tomography, or magnetic resonance imaging examination. Although the majority of such lesions can be easily detected and correctly characterized, misdiagnoses may occur and are often related to methodological limitations, inappropriate imaging protocols, or misinterpretation. This pictorial essay provides recommendations on how to recognize benign and malignant renal processes that can be potentially missed or mischaracterized in imaging studies.

“…Дифференциальная диагностика. КТ брюшной полости вследствие ее распространенности, высокой чувствительности и специфичности является наиболее часто используемым методом визуализации в выявлении АМЛ, а также дифференциальной диагностике с иными новообразованиями почек [18]. В дифференциальный ряд входят опухоли, которые могут иметь в структуре жировые включения, такие как почечно-клеточный рак (ПКР), почечные липосаркомы, нефробластомы.…”

The paper presents two clinical cases of patients with giant renal angiomyolipomas (AML), in one of whom its course was complicated by intratumoral hemorrhage. It describes key diagnostic criteria for computed tomography (CT), as well as the distinctive features of other neoplasms that should undergo a differential diagnosis. The similar clinical presentations and morphological characteristics of different renal neoplasms can cause certain diagnostic difficulties; however, the carefully collected historical data and distinctive criteria allow AML to be identified. Due to its high sensitivity and specificity, abdominal contrast-enhanced CT is an effective imaging technique in the detection and differential diagnosis of giant renal AML.
