Hypertrophic column of Bertin

The renal column of Bertin is a medullary extension of the renal cortex in between the renal pyramids. Hypertrophic column of Bertin (HCB) is a normal variant that appears as […]

Post-biopsy bleeding

Compared with biopsy of other sites, native renal biopsy has the greatest risk of post-procedure hemorrhage (1.2%). However, the incidence of major bleeding and death due to bleeding is very […]

The jellyfish sign: atelectasis

In moderate to large pleural effusions, it’s not uncommon to see lung atelectasis on the ultrasound. This collapsed lung within the effusion moves with respiration and appears like a jellyfish. […]

Ultrasound signs of urolithiasis

Although sonography is less sensitive than CT for detecting kidney stones, it is the preferred initial imaging modality as there is no risk of radiation, is reproducible, inexpensive, and the […]

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 […]

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 […]

Renal cyst: simple or complex?

The diagnosis of a simple benign renal cyst on ultrasound requires the presence of all the following findings: a well-defined, roundish, anechoic structure, imperceptible near wall and thin echogenic far […]

Mirror image artefact

This is one of the commonest artefacts encountered in NephroPOCUS. It is generated by the false assumption that an echo returns to the transducer after a single reflection. In this […]

PLAX view: Orientation

The parasternal long axis view or the PLAX is obtained by placing the transducer to the left of the sternum in 3rd or 4th intercostal space with the orientation marker […]
