RESUMEN
INTRODUCTION: The present study indicates that simple and hydatid cysts in liver are a common health problem in Turkey. The aim of the study is to differentiate different types of hydatid cysts from simple cysts by using diffusion-weighted images. MATERIALS AND METHODS: In total, 37 hydatid cysts and 36 simple cysts in the liver were diagnosed. We retrospectively reviewed the medical records of the patients who had both ultrasonography and magnetic resonance imaging. We measured apparent diffusion coefficient (ADC) values of all the cysts and then compared the findings. RESULTS: There was no statistically meaningful difference between the ADC values of simple cysts and type 1 hydatid cysts. However, for the other types of hydatid cysts, it is possible to differentiate hydatid cysts from simple cysts using the ADC values. CONCLUSION: Although in our study we cannot differentiate between type I hydatid cysts and simple cysts in the liver, diffusion-weighted images are very useful to differentiate different types of hydatid cysts from simple cysts using the ADC values.

INTRODUCTION: Shear wave elastography is a method for the measurement of tissue stiffness. The advantage of this method is that its outcome is not operator dependent. Our aim was to compare the elastiscity values of the right lobe of the liver of normal weighted and morbidly obese patients. MATERIALS AND METHODS: The mean elastiscity values of the right lobe of the liver were calculated for 38 normal weighted and 37 morbidly obese patients. All the patients had no history of liver disease. RESULTS: The mean elastiscity value was significantly higher in morbidly obese patients than (25,7 +3,30 kPascal) in normal weighted patients for the right lobe of liver (10,55 +2,20 kPascal). CONCLUSION: Morbidly obese patients have a potential risk for liver fibrosis even in the absence of hepatosteatosis.

INTRODUCTION: Chronic otitis media (COM), affecting all over the world and in a wide range of age groups in Turkey, is an important cause of ear discharge and hearing loss. The main clinical manifestations are tympanic membrane perforation, ear, nose and throat problems. On the tympanic membrane perforation becomes persistent and cholesteatoma development, there are a lot of opinions today. Especially in the pathology associated with otitis media with effusion eustachian tube, it is known that COM and cholesteatoma develop. MATERIALS AND METHODS: In our study, we interpreted 210 patients' temporal computed tomography (CT). Seventy of these 210 patients had otitis media with cholesteatoma, 70 patients had only otitis media without cholesteatoma, and 70 patients had no otitis media. The eustachian tubes were evaluated using temporal CT multiplanar reconstruction method. Angles with the horizontal plane of the eustachian tube and Reid and tubotympanic angles were measured. RESULTS: The angles between eustachian tube and horizontally oriented Reid plane of the patients with cholesteatoma were found to be significantly lower than the patients with otitis media without cholesteatoma and the patients with no history of otitis media. For the tubotympanic angle, no statistically significant differences were observed between the groups. CONCLUSION: These results suggest that the decrease in the angle with the horizontal plane of Reid in the eustachian tube in adults may play a significant role in the etiology of cholesteatoma.
