- Eosinophilic Solid and Cystic Renal Cell Carcinoma: Imaging Features of a Novel Neoplasm(2018) FENELON, Sandro Santos; SANTOS, Joao Manoel Miranda Magalhaes; FARAJ, Sheila Friedrich; MATTEDI, Romulo Loss; TRPKOV, Kiril; NAHAS, William Carlos; GARCIA, Marcio Ricardo Taveira; VIANA, Publio Cesar CavalcanteEosinophilic solid and cystic renal cell carcinoma (ESC RCC) is a recently described entity with distinct clinical, pathologic, and molecular features. However, the radiological aspects of ESC RCC have not been characterized. In this report, we describe the imaging findings of 2 ESC RCCs. We found 2 distinct imaging patterns that varied depending on histopathologic features (solid or cystic predominance). In conclusion, it is important to know the imaging characteristics and pathologic correlation of this novel neoplasm to increase its recognition and to improve the decision-making process.

- Abdominal gastrointestinal imaging findings on computed tomography in patients with COVID-19 and correlation with clinical outcomes(2021) HORVAT, Natally; PINTO, Paulo Victor Alves; ARAUJO-FILHO, Jose De Arimateia Batista; SANTOS, Joao Manoel Miranda Magalhaes; DIAS, Adriano Basso; MIRANDA, Julia Azevedo; OLIVEIRA, Camila Vilela de; BARBOSA, Camila Silva; MORAIS, Thamara Carvalho; ASSUNCAO-JR, Antonildes N.; NOMURA, Cesar Higa; VIANA, Publio Cesar CavalcantePurpose: Pulmonary imaging finding of Coronavirus disease 2019 (COVID-19) has been widely described, but until now few studies have been published about abdominal radiological presentation. The aim of this study was to provide an overview of abdominal imaging findings in patients with COVID-19 in a multicenter study and correlate them with worse clinical outcomes. Materials and methods: This retrospective study included adult COVID-positive patients with abdominal CT performed from 4/1/2020 to 5/1/2020 from two institutions. Demographic, laboratory and clinical data were recorded, including clinical outcomes. Results: Of 81 COVID-positive patients, the average age was 61 years, 42 (52%) women and 45 (55%) had positive abdominopelvic findings. The most common abdominal imaging features were intestinal imaging findings (20/81, 24%), including colorectal (4/81, 5%) and small bowel thickening (10/81, 12%), intestinal distension (15/81, 18%), pneumatosis (1/81, 1%) and intestinal perforation (1/81, 1%). On multivariate analysis, intestinal imaging findings were associated with higher risk of worse outcome (death or invasive mechanical ventilation) (RR = 2.6, p = 0.04) and higher risk of invasive mechanical ventilation alone (RR = 6.2, p = 0.05). Conclusion: Intestinal abnormalities were common findings in COVID-19 patients who underwent abdominal CT and were significantly correlated to worse outcomes in the clinical follow-up.
- Case 297(2021) KANAS, Alexandre Fligelman; FENELON, Sandro Santos; SANTOS, Joao Manoel Miranda Magalhaes; COELHO, Rafael Ferreira; GUGLIELMETTI, Giuliano Betoni; NAHAS, William Carlos; VIANA, Publio Cesar CavalcanteHistory A 70-year-old man was referred to our institution with chronic obstructive urinary symptoms and constipation for 2 years before admission. His medical history was unremarkable. Outside laboratory tests revealed an elevated serum prostate-specific antigen level (21.7 ng/mL [normal range, 0.00-4.00 ng/mL]), and urinalysis results were negative. He was admitted for evaluation of possible prostate cancer. The patient reported no specific symptoms of infection and denied fever, dysuria, hematuria, and abdominal pain. He had no family history of prostate cancer. On physical examination, he was afebrile, and the digital rectal examination was not painful. These findings were evidence of an enlarged prostate and a hard multilobulated mass, which was palpable bilaterally. The urologic team performed MRI of the prostate (Figs 1-4)
