PURPOSE: To introduce a rare variant branching pattern of the portal vein with clinical relevance. METHODS: A 55-year-old man was examined by contrast-enhanced computed tomography to investigate the cause of fever and mildly elevated hepatic enzyme levels. RESULTS: Based on computed tomography, liver abscesses were identified which may have caused the fever and elevated hepatic enzyme levels. And a variation in the branching pattern of the portal vein was also detected in this patient, which has not been reported previously; the right posterior portal vein originated from the end of the horizontal part of the left portal vein...

We report an extremely rare case of fenestration of the supraclinoid internal carotid artery (ICA) diagnosed by magnetic resonance (MR) angiography. The smaller channel arose from the paraclinoid ICA aneurysmal dilatation, and the posterior communicating artery arose from the distal end of the fenestration. Careful observation of MR angiographic images, including source images, is important to detect rare arterial variations, and their identification on MR angiography is aided by the creation of partial maximum-intensity-projection images and partial volume-rendering images...

This study is focused on the vascular anatomy of the stomach in relation to the gastric pull-up construction. The vascular anatomy was studied on forty-one human specimens. We find out the differences in blood supplement between anterior and posterior wall. It was maked an review of the main trunk arteries of the stomach. To display the vessels of the stomach we used diaphanoscopy, digital shooting in special mode and micro preparation of the vessels. We find out that left gastric artery gives more branches to the posterior wall and right gastroepiploic artery (RGEA) gives more branches to the anterior wall...

Reports of congenital anomalies of the Eustachian Tube (ET) are scarce, and often associated with chromosomal abnormalities. We report a unique case of a completely bony left Eustachian tube which communicated with the sphenoid sinus. This report details these findings and discusses the potential embryological basis and implications of such an unusual anatomy, in the context of a comprehensive literature review.

PURPOSE: Arachnoid granulations (AGs) occasionally appear to protrude into the calvarial convexity, lying close to the bridging veins (BVs). This study aims to characterize such AGs and BVs using magnetic resonance imaging (MRI). METHODS: Ninety-five patients were enrolled in this study. Initially, stepwise frontal craniotomy was performed in an injected cadaver head. Next, examinations with contrast MRI were performed involving the whole cranial vault. RESULTS: In cadaveric dissection, the AGs located in the parasagittal regions appeared as outward protrusions through the dura mater and in contact with the diploic veins...

PURPOSE: Muscles have been proved to be a major component in postural regulation during pathological evolution or aging. Particularly, spinopelvic muscles are recruited for compensatory mechanisms such as pelvic retroversion, or knee flexion. Change in muscles' volume could, therefore, be a marker of greater postural degradation. Yet, it is difficult to interpret spinopelvic muscular degradation as there are few reported values for young asymptomatic adults to compare to. The objective was to provide such reference values on spinopelvic muscles...
