We report here an extremely rare case of hepatic sclerosing hemangioma mimicking a biliary cystadenocarcinoma. A previously healthy 39-year-old woman was referred to our hospital because of a large tumor in the liver. Abdominal computed tomography revealed early peripheral ring enhancement in the arterial phase and slight internal heterogeneous enhancement in the delayed phase. Magnetic resonance imaging revealed a tumor with low intensity in the T1-weighted image and very high intensity in the fat-saturated T2-weighted image. The patient underwent hepatectomy for a possible malignant liver tumor. Grossly, the tumor appeared as a white, solid, and cystic mass (weighted 1.1 kg and measured 170×100×80 mm) that was elastic, soft, and homogeneous with a yellowish area. Histological examination showed that the tumor mostly consisted of fibrotic areas with hyalinization. The typical histology of cavernous hemangioma was confirmed in part, and the tumor was diagnosed as a sclerosing hemangioma with predominancy of the sclerosed area. A review of 20 cases reported previously revealed that only 2 (10%) patients were diagnosed as having sclerosing hemangioma preoperatively.

The most common primary malignant liver tumor of childhood, hepatoblastoma has increased in incidence over the last 30 years, but little is still known about its pathogenesis. Discoveries in molecular biology provide clues but have yet to define targeted therapies. Disease-free survival varies according to stage, but is greater than 90% in favorable risk populations, in part due to improvements in chemotherapeutic regimens, surgical resection, and earlier referral to liver transplant centers. This article aims to highlight the principles of disease that guide current treatment algorithms. Surgical treatment, especially orthotopic liver transplantation, will also be emphasized in the context of the current Children’s Oncology Group international study of pediatric liver cancer (AHEP-1531).

Rationale: Crohn's disease is characterized by continuous severe course, and in a half of the patients is associated with formation of strictures that are difcult to treat and signifcantly decrease quality of life. Difculties during the differentiation between inflammation-related and fbrostenotic strictures and divergent approaches to their treatment in patients with Crohn's disease indicate the need in precise diagnostics and systematization of the radiological semiotics of strictures.Aim: To propose radiological semiotics of the small and large intestine strictures based on the results of multiaxial computed tomography (MACT) and magnetic resonance imaging (MRI).Materials and methods: MACT and MRI visualization was performed in 40 patients with a stenotic type of Crohn's disease.Results: The radiological signs of the strictures were classifed into two main groups: intestinal and extra-intestinal. They were systematized according to nine criteria, such as character of formation, etiology, number, inflammation grade, extension, shape, and location, presence of ileus and presence of other complications. The inflammation activity in the intestinal wall was evaluated during the postcontrast assessment: active inflammation in the arterial phase (at 25 seconds after administration of the contrast agent), chronic inflammation in the delayed phase (at 10 minutes). The MRI results were cross-checked with those of MACT. At the precontrast stage, MRI was more informative as per the width of the intestinal lumen, whereas MACT was preferential in the diagnosis of fat infltration of the intestinal wall. Post-contrast MACT and MRI were diagnostically equivalent. The most indicative for active inflammation were diffuse weighed MRI images, arterial phase MACT and MRI, whereas chronic inflammation and wall fbrosis were better diagnosed at the delayed phase (at 10 minutes) of MACT and MRI. Both methods (MACT and MRI) could not differentiate between the submucous and muscular layers of the intestinal wall. Mixed type of inflammation was seen in the walls of intestinal strictures: chronic inflammation dominated in the intermediate, most extensive part of a stricture and remained stable during the dynamic follow-up, whereas active inflammation was found in the marginal parts of the strictures, which were most susceptible to changes during the follow-up.Conclusion: Based on a set of certain signs obtained by radiological visualization, we propose a registry for stricture assessment based on evaluation of the inflammation activity.

Objectives. To assess the potential of CT for characterizing small renal tumors.Methods. 76 patients with <4 cm renal tumors underwent CT examination. The following parameters were assessed: presence of calcifications, densitometry on unenhanced and enhanced scans, washout percentage, urinary tract infiltration, star-shaped scar, and paradoxical effect.Results. Calcifications were found in 7/56 (12.5%) carcinomas. Clear cell carcinomas were as follows: mean density 183.5 HU (arterial phase), 136 HU (portal phase), and 94 HU (delayed phase), washout 34.3%; chromophobe carcinomas were as follows: mean density 135 HU (arterial phase), 161 HU (portal phase), and 148 HU (delayed phase), washout 28%; papillary carcinomas were as follows: mean density 50.3 HU (arterial phase), 60 HU (portal phase), and 58.1 HU (delayed phase), washout 2.7%. In 2/56 (3.6%) cases urinary tract infiltration was found. Oncocytomas were as follows: mean density 126.5 HU (arterial phase), 147.5 HU (portal phase), and 115.5 HU (delayed phase), washout 28.6%. On unenhanced scans, angiomyolipomas were as follows: density values <30 HU in 12/12 (100%) of cases and on enhanced scans: mean density 78 HU (arterial phase), 128 HU (portal phase), and 80 HU (delayed phase), washout 50%.Conclusions. Intralesional calcifications and urinary tract infiltration are suggestive for malignancy, with the evidence of adipose tissue for angiomyolipomas and a modest increase in density with a reduced washout for papillary carcinomas. The intralesional density on enhanced scans, peak enhancement, and washout do not seem significant for differentiating clear cell, chromophobe carcinomas, angiomyolipomas, and oncocytomas.

Objective. This study was performed to assess the value of quantitative analysis of enhanced computed tomography (CT) values in the differential diagnosis of bladder cancer and cystitis glandularis (CG). Methods. Eighty patients with bladder masses (39 with CG and 41 with bladder cancer) who underwent enhanced CT were retrospectively reviewed. The CT enhancement values of the lesion and normal bladder wall in the arterial phase, venous phase, and delayed phase were measured. The relative enhancement CT values (relative enhancement CT value=enhancement CT value of lesion−enhancement CT value of normal bladder) in the arterial phase, venous phase, and delayed phase were also calculated. The pathological results were used as the gold standard, and the area under the curve (AUC), sensitivity, and specificity were calculated for the six groups of quantitative indicators (enhanced CT values and relative enhanced CT values of CG and bladder cancer in the arterial, venous, and delayed phases). We performed the leave-group-out cross-validation method to validate the accuracy, AUC, sensitivity, and specificity. The differences in accuracy, AUC, sensitivity, and specificity among the six groups of quantitative indicators were compared by the t-test. Results. In a combined analysis of the AUC, sensitivity, and specificity performance, the best indicator was the arterial-phase relative enhancement CT value with a cut-off of 25.85 HU (AUC, 0.966; sensitivity, 95.1%; specificity, 92.3%). We used the 100-times leave-group-out cross-validation method to validate the accuracy, AUC, sensitivity, and specificity. Arterial-phase relative enhancement CT values showed the highest AUC and accuracy among the six groups, with statistical significance (P<0.05). Conclusion. Quantitative analysis of enhanced CT is of great clinical value in the differential diagnosis of CG and bladder cancer.
