Do kidneys sweat?
An extracapsular, hypoechoic or anechoic rim of simple-appearing fluid surrounding the kidneys, first described on ultrasonography in some patients with renal failure (serum creatinine >2 mg/dL), was termed kidney sweat. […]
B lines do not always indicate pulmonary edema
Diffuse B-line pattern can be seen in pulmonary edema of various causes, interstitial pneumonia and diffuse parenchymal lung disease (e.g. fibrosis), contusion etc. Whether you are dealing with pulmonary edema […]
Ureteral jets
The intravesical ureteral jets, or the bladder jets represent the sonographic appearance of discrete boluses of urine entering the bladder, better detected using color Doppler. They are thought to result […]
Pneumonia and dynamic air bronchograms
In general, evaluation of an air-rich organ is a limitation of ultrasound because air scatters the ultrasound beam and does not allow proper visualization of the underlying structures. Therefore, normal […]
Performance of lung ultrasound: Let’s talk numbers
The diagnostic accuracy of lung ultrasound for common pathologies such as pleural effusion, pulmonary edema, pneumothorax, and pneumonia is superior to chest radiograph and is comparable to chest CT scan. […]
Vasculature mimicking hydronephrosis on greyscale ultrasound
Fluid (e.g. blood, urine, serous fluid in cysts) is an excellent transmitter of sound waves and appears black (= anechoic) on a sonogram. On greyscale images, prominent vasculature or vascular […]
Dromedary hump
Dromedary hump is a prominent focal bulge on the lateral border of the left kidney caused by splenic impression, which can mimic renal neoplasm. It is similar in appearance to […]
Urinary bladder wall thickness: what is the number to remember?
It is not uncommon to see a thickened urinary bladder wall in cases of chronic bladder outlet obstruction. Have you ever wondered how thick is thick? In a study, a […]
Thickened gall bladder wall: not always acute cholecystitis
In clinical practice, a cut off of 3mm is commonly used to define the upper limit of normal gall bladder wall thickness and acute cholecystitis is one thing that comes […]
