Video of parasternal long-axis bedside transthoracic echocardiogram: The initial images showed grossly normal left ventricular function, and no pericardial effusion or evidence of cardiac tamponade. However, the proximal aorta beyond the aortic valve was poorly-visualized in this window.

Point-Of-Care Ultrasound for the Diagnosis of Extensor Tenosynovitis

Point-of-care ultrasound of the dorsal aspect of the left hand reveals a heterogenous hypoechoic fluid collection surrounding the extensor tendons (axial view) within the retinaculum consistent with edema. Longitudinal view shows anechoic fluid within the tenosynovium which is located between the anisotropic extensor tendon and linear hyperechoic synovial sheath. Longitudinal view also shows some cobblestoning, or tissue edema, superficial to the anisotropic extensor tendon. The patient’s contralateral right dorsal hand was scanned in a longitudinal view and shows no cobblestoning or hypoechoic fluid under the synovial sheath. The patient was diagnosed with tenosynovitis, and started on intravenous antibiotics.

Bladder POCUS demonstrated 500mL of post void residual fluid, indicative of retention. Half of the volume is hyperechoic (red circle); this is likely the bladder wall hematoma. Could also consider sonographic artifact, bladder mass, or cystitis.1-2

Point-of-Care Ultrasound to Evaluate Intrahepatic Biliary Stent Function

The ultrasound image demonstrates severe intrahepatic biliary ductal dilatation without an obvious intrahepatic obstructive lesion, as pointed out by the white arrows. The hepatic vasculature is well-distinguished from the biliary tree via color flow doppler, as seen by the white arrowheads.

Focused assessment with sonography in trauma (FAST) scan was positive for a clinically significant pericardial effusion as evidenced by the hypoechoic fluid around the myocardium, indicated by the blue arrow in image 2. Findings are also consistent with tamponade process as evidenced by restricted expansion and collapse of the right ventricle during diastole. The hyperechoic floating structure between the pericardium and myocardium, adjacent to the right ventricle, represents a pericardial clot, indicated by the white arrow.The density of the pericardial clot differs from that of the myocardium, thus serving as an additional variable to avoid confusing this as part of the myocardial structure.

Radiolucent Foreign Body Seen on Point-of-Care Ultrasound but not on X-ray

DOI: https://doi.org/10.21980/J8WS77Issue 4:1 No ratings yet.

X-rays of the foot were obtained and no radiopaque foreign body was visualized. Due to high clinical suspicion for retained foreign body, a point-of-care ultrasound was performed by applying a high-frequency linear probe at the area of discomfort. In the long axis an ovoid focus of hypoechogenicity (orange outline) is visualized. Within this finding there is a linear focus (yellow line) of increased echogenicity measuring 1 mm in diameter and 1 cm in length. On short axis view, a rectangle focus (green dot) demonstrating shadowing (blue highlight) is seen.

Low-Cost, Low Fidelity Meat Model to Teach Ultrasound Guided Nerve Blocks

Upon completion of this workshop, learners will be able to: 1) Describe the risks and benefits of ultrasound guided nerve blocks. 2) Choose the appropriate nerve to block based on the area that needs anesthesia. 3) Display proficiency in performing an ultrasound guided nerve block on meat models. 4) Verbalize confidence in successfully performing ultrasound guided regional anesthesia. By successfully meeting these objectives, we aim to improve learner confidence and clinical ability in performing ultrasound guided nerve blocks.

Bedside ocular ultrasound revealed a serpentine, hyperechoic membrane that appeared tethered to the optic disc posteriorly with hyperechoic material underneath. These findings are consistent with retinal detachment (RD) and associated retinal hemorrhage.

History of present illness: While watering his lawn, a 36-year-old man felt two sharp bites to his bilateral ankles. He reports that he then saw a light brown, 2-foot snake slither away from him. He came to the emergency department because of pain and swelling in his ankles and inability to bear weight. Physical examination revealed bilateral ankle swelling and
