Carcinoma of unknown primary with hepatic metastases: a need of judicious and contemplative diagnostic algorithm
AbstractCarcinoma of Unknown Primary presenting primarily as hepatic metastases encompasses a dismal subgroup of tumors with a median survival of 5.9 months. Adenocarcinoma is the most common histological subtype identified upon biopsy and the primary tumor remains undetectable in the majority of cases despite extensive workup. It is important to have a validated and standardized algorithm to follow these tumors to avoid unnecessary tests, as the wishes and health status of the patient represent the principal concerns. The purpose of this paper is to briefly review the current literature on carcinoma of unknown primary wit...

Tension hydrocele as an additional cause of acute scrotum: case series and literature review
ConclusionTo conclude, tension hydrocele is a rare condition that produces alterations of form and circulation of testicles, increase of intraparenchymal vascular resistances and strong and continuous pain, mimicking a testicular torsion. The increase in pressure produces an effect similar to that observed in a compartment syndrome. US findings, together with clinical assessment, indicate when emergency decompression may be appropriate to relieve testicular ischemia. (Source: Abdominal Imaging)

AbstractMRI and MRCP play an important role in the diagnosis of chronic pancreatitis (CP) by imaging pancreatic parenchyma and ducts. MRI/MRCP is more widely used than computed tomography (CT) for mild to moderate CP due to its increased sensitivity for pancreatic ductal and gland changes; however, it does not detect the calcifications seen in advanced CP. Quantitative MR imaging offers potential advantages over conventional qualitative imaging, including simplicity of analysis, quantitative and population-based comparisons, and more direct interpretation of detected changes. These techniques may provide quantitative metri...
