aneurysmal bone cyst (abc) is an expansile bone lesion that usually involves the long bones. skull base involvement is rare. hereby, we describe a 17-year-old man with hoarseness, facial asymmetry, left sided sensorineural hearing loss and left jugular foramen syndrome. ct scan and mri showed a skull base mass that was confirmed as abc in histopathology. the case was unusual and interesting due...

Herein, we report the F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) findings of a benign solitary fibrous tumor (SFT) of the kidney. The patient was a 63-year-old woman with a mass in the right kidney (10×9.7 cm), incidentally found on CT images. The CT scan showed a lobulated tumor arising from the hilum of the right kidney. The tumor consisted o...

OBJECTIVE We wanted to describe the computed tomography (CT) findings of gallbladder tuberculosis (TB) and to correlate them with pathologic findings. MATERIALS AND METHODS There were seven patients (M:F = 3:4; mean age, 46.3 years; age range, 32 to 78 years) in whom gallbladder TB was eventually diagnosed. All of them underwent cross-sectional imaging with CT, a pathologic examination and a ...

We report a case of multiple myeloma with gastric involvement occurring in a patient who underwent an upper gastrointestinal series (UGIS), CT and MRI. UGIS depicted a luminal protruding mass, while contrast-enhanced CT demonstrated marked thickening of the gastric wall, with subtle contrast enhancement. At T1- and T2-weighted MR imaging, the mass showed iso- and intermediate signal intensity, ...

hydatid disease (hd) is a parasitic infection that is most commonly caused by the larval stage of echinococcus granulosus. unusual location for this disease can cause diagnostic and therapeutic problems. we herein report a case of sacrococcygeal hd at an unusual location in a 30-year-old woman. she was evaluated using computed tomography (ct) imaging and magnetic resonance imaging (mri) after t...

This report describes a sclerosing hemangioma of the lung evaluated by MRI. The mass demonstrated hyperintense signal on T1-weighted, proton density, and T2-weighted spin-echo images. Contrast-enhanced T1-weighted imagesshowed marked, homogeneous enhancement of the mass. The MR appearance is not specific for sclerosing hemangioma of the lung, as other benign tumors can appear similarly. However...

In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...

The current article has investigated unsteady convective flow for MHD non-Newtonian Powell-Eyring fluid embedded porous medium over inclined permeable stretching sheet. We have pondered the thermophoresis parameter, chemical reaction, variable thermal conductivity, Brownian motion, variable heat source and variable thermal radiation in temperature and concentration profiles. Using similar trans...

Stress induced enhancement of electron mobility has primarily been attributed to the splitting of the conduction bands. However, experiments [1] have indicated that the mobility enhancement cannot solely be attributed to this effect, and a recent study has shown that a stress along the 〈110〉 direction leads to a change of the effective mass [2]. This work investigates the effect of the variatio...

We report a comprehensive THz, infrared and optical study of Nb-doped SrTiO3 as well as dc conductivity and Hall effect measurements. Our THz spectra at 7 K show the presence of an unusually narrow (<2 meV) Drude peak. For all carrier concentrations the Drude spectral weight shows a factor of three mass enhancement relative to the effective mass in the local density approximation, whereas the s...
