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.
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.
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.
POCUS of the small bowel illustrated significantly dilated loops of bowel (white line), thickened bowel wall (white arrow) and to-and-fro peristalsis, consistent with small bowel obstruction.
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
History of present illness: A 27-year-old female sustained an injury to her left hand after she tripped and fell on a vase. She presented to the emergency department (ED) complaining of pain over the laceration. Upon examination, patient presented with multiple small abrasions of the medial aspect of the left 5thdigit that are minimally tender. Additionally, she has one 0.5cm
POCUS reveals a large, hypoechoic soft tissue abscess with debris and tracks extending to the bottom of the image. Furthermore, when compressed, movement of the abscess contents is appreciated. There is also superficial cobble-stoning consistent with overlying cellulitis and soft tissue edema.

The patient’s ultrasound revealed an attached retina and a complex network of hyperechoic, mobile, membranous material in the posterior segment.
