RESUMO

Zinner's syndrome is a rare congenital malformation characterized by the association of unilateral renal agenesis with ipsilateral seminal vesicle cyst and ejaculatory duct obstruction. Most patients are asymptomatic until the third or fourth decade of life when the syndrome is associated with dysuria, perineal pain, infertility, and painful ejaculation. In this report, we present the common imaging findings of this rare developmental anomaly involving the mesonephric duct in a 48-year-old male patient experiencing pelvic pain, recurrent dysuria, and pollakiuria.

RESUMO

Contrast-enhanced ultrasound (CEUS) is gaining ever-increasing acceptance in the preoperative and postoperative evaluation of liver-transplanted patients. While indications are still a matter of research, CEUS is used in tertiary centers to supplement ultrasound (US) and Color Doppler US examination, with the potential of providing a comprehensive first-line ultrasound-based diagnosis. Alternatively, CEUS is used as a problem-solving tool when previous cross-sectional or US imaging was inconclusive, especially in assessing hepatocellular carcinoma, parenchymal perfusion abnormalities, the vascular status, and even the biliary tree. This review describes the potential use for CEUS in the setting of orthotopic liver transplantation (OLT).

RESUMO

BACKGROUND: Native hepatectomy represents the most demanding surgical step during orthotopic whole liver transplantation (LT). The surgical risk assessment of LT candidates is currently mainly based on clinical and laboratory data, but even preoperative imaging data may be predictive of a complex native hepatectomy. METHODS: A retrospective study on a cohort of 110 LT recipients was conducted. The radiologic variables investigated on pre-LT multidetector computed tomography scan were the length of the retrohepatic inferior vena cava (IVC-L), volume of the dorsal liver sector (DLS-V), complete encirclement of the IVC by the DLS (IVC-CE), max diameter of the native liver (L-D), max diameter of the spleen (S-D), and presence of large spontaneous portosystemic shunts (SPSS). The parameters defining complex native hepatectomy were the operative time, number of red blood cell (RBC) units transfused, IVC replacement technique switch, and post-LT relaparotomy for major bleeding. RESULTS: In a multivariate analysis, the operative time was predicted by hepatocellular carcinoma (HCC) diagnosis (regression coefficient [RC]: 18.237, P = .009), S-D (RC: 3.733, P = .007), and IVC-CE (RC: 20.174, P = .01); the RBC units transfused by an history of gastroesophageal variceal bleeding (RC: 2.503, P = .039), Model for End-Stage Liver Disease (MELD) score (RC: .259, P = .039), and L-D (RC: -0.519, P = .027); the switch to a IVC replacement technique by L-D (odds ratio [OR]: 0.641, P = .028) and IVC-L (OR: 1.065, P = .023); and the relaparotomy for bleeding by L-D (OR: 0.632, confidence interval [CI]: 0.437 to 0.916, P = .015). CONCLUSIONS: Pre-LT multidetector computed tomography (MDCT) seems to be a very useful tool in the surgical risk assessment of LT candidates.
