The first video is an intraoral ultrasound using the high frequency endocavitary probe demonstrating an anechoic fluid collection adjacent to the patient’s enlarged left tonsil. The second video shows real-time ultrasound-guided successful drainage of the PTA.

Using Bedside Ultrasound to Rapidly Differentiate Shock

Mohamad Moussa, MD*, Jacob Willen, BS* and Sudipa Biswas, BS, MS*

DOI: https://doi.org/10.21980/J8S047 Issue 2:3[mrp_rating_result]
A RUSH exam demonstrated hyperdynamic cardiac contractility and collapse of the inferior vena cava (IVC) with probe compression more than 50% suggesting hypovolemia likely secondary to sepsis. Incidentally, Morrison’s pouch revealed a large right renal cyst but no signs of free fluid. A computed tomography of abdomen/pelvis showed a 10.8 x 9.5 cm right renal cyst and left lower lobe pneumonia.

Pneumonia Diagnosed by Point-of-Care Ultrasound

Akash Patel, BA*, Steven Bunch, MD^, Maili Alvarado, MD^, Shadi Lahham, MD^ and J. Christian Fox, MD^

DOI: https://doi.org/10.21980/J8XP64 Issue 2:3[mrp_rating_result]
Point-of-care ultrasound of the left lower lobe demonstrates lung hepatization, a classic finding for pneumonia. In addition, a shred sign is present with both air bronchograms and focal B-lines—all suggestive of poorly aerated, consolidated lung. The patient was started on antibiotics and admitted to the hospital with a diagnosis of community-acquired pneumonia.

Use of Bedside Compression Ultrasonography for Diagnosis of Deep Venous Thrombosis

Mohamad Moussa, MD* and Maher Abdo, BS*

DOI: https://doi.org/10.21980/J81G94 Issue 2:3[mrp_rating_result]
As shown in the still image of the performed ultrasound, a transverse view of the proximal-thigh revealed a visible thrombus (green shading) occluding the lumen of the left common femoral vein (blue ring), which was non-compressible when direct pressure was applied to the probe. Also visible is a patent and compressible branch of the common femoral vein (purple ring) and the femoral artery (red ring), highlighted by its thick vessel wall and pulsatile motion.

A Toddler with Abdominal Pain and Emesis

Saema Said, BS* and Kevin Koenig, MD*

DOI: https://doi.org/10.21980/J8XW2P Issue 2:2[mrp_rating_result]
In the long axis video, the appendix appears as an enlarged, non-compressible, blind-ending tubular structure (white arrow) with distinct appendiceal wall layers and lack of peristalsis. In the short axis video, the appendix appears as a target sign (yellow arrow) between the abdominal and psoas muscles. The maximal outer diameter (MOD) measures 11.8mm and the appendix wall measures 0.17mm. There is trace adjacent free fluid and echogenic periappendiceal fat. Transverse axis video and image (red arrow) demonstrate that the appendix is not compressible. These findings are consistent with acute appendicitis.
