- 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.

- Associating Liver Partition and Portal vein ligation for Staged hepatectomy procedure using ischemic bipartition Two case reports(2018) MACHADO, Marcel C. C.; ABE, Emerson S.; DUMARCO, Rodrigo; VIANA, Publio; MACHADO, Marcel Autran C.Rationale: The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure is a recently introduced treatment strategy for patients with advanced primary or metastatic liver tumors and small future liver remnants. ALPPS procedure using ischemic bipartition of the liver is a modified technique that may reduce complications compared to classical ALPPS. Patient concerns: Two patients with multiple colorectal liver metastasis with extensive involvement of the liver were considered unresectable before treatment because of small future liver remnant (FLR). Diagnoses: Two patients were diagnosed by imaging examination with volumetry of the liver. Interventions: In the first stage, ischemic bipartition of the liver is achieved using radiofrequency ablation. The Glissonian pedicles from Segment 4 are identified and ablated, the FLR is cleared, and the right portal vein is ligated. In the second stage, the typical procedure is performed, and an extended liver resection is performed. Outcomes: The procedure was feasible with acceptable hypertrophy of FLRs. Blood transfusions were unnecessary, and severe postoperative complications were avoided. Lessons: The ALPPS procedure with ischemic bipartition is safe and feasible and can produce results that are the same as those of the classical ALPPS procedure while reducing invasiveness during the first stage.
- Current concepts in multiparametric magnetic resonance imaging for active surveillance of prostate cancer(2018) CAVALCANTE, Alexandre; VIANA, Publio Cesar C.; GUGLIELMETTI, Giuliano B.; PONTES, Jose; NONEMACHER, Henrique; CORDEIRO, Mauricio D.; BEZERRA, Regis Otaviano F.; COELHO, Rafael F.; NAHAS, William Carlos
- Extensive renal sinus lipomatosis in xanthogranulomatous pyelonephritis simulating liposarcoma(2018) ANDO, Sabrina de Mello; MORENO, Raquel Andrade; VIANA, Publio Cesar Cavalcante; YAMAUCHI, Fernando IdeRenal replacement lipomatosis is a condition characterized by varying degrees of renal parenchymal atrophy and perirenal fibrofatty proliferation secondary to chronic inflammation such as xanthogranulomatous pyelonephritis. In severe cases, imaging findings can be misdiagnosed as retroperitoneal liposarcoma.
