Point-of-care Ultrasound for the Diagnosis of a Gluteal Abscess

Kevin Roy, BS*, Robert Rowe, MD* and Maili Alvarado, MD^

DOI: https://doi.org/10.21980/J8VH1W Issue 3:1[mrp_rating_result]
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.

Perianal Abscess

Luke Walls-Smith, BS* and Jonathan Peña, MD*

DOI: https://doi.org/10.21980/J8QP81Issue 3:1[mrp_rating_result]
Computed Tomography (CT) of the Pelvis with intravenous (IV) contrast revealed a 5.7 cm x 2.4 cm air-fluid collection in the right perianal soft tissue along the right gluteal cleft, with surrounding fat stranding, consistent with a perianal abscess with cellulitis.

Acute Pyelonephritis with Perinephric Stranding on CT

Ronald Goubert* and Jonathan Peña, MD*

DOI: https://doi.org/10.21980/J8BH0VIssue 3:1[mrp_rating_result]
A CT abdomen and pelvis with IV contrast showed neither nephrolithiasis nor diverticulitis, and instead showed heterogeneous enhancement of the left kidney with mild edematous enlargement and striated left nephrogram. Significant perinephric stranding (red arrows) was also noted and was consistent with severe acute pyelonephritis.

Empyema

Jonathan Patane, MD* and Daniel Ritter, BS^

DOI: https://doi.org/10.21980/J86P9RIssue 3:1[mrp_rating_result]
The chest X-ray shows a large fluid collection in the right lung demonstrated by the opacification that blunts the costophrenic angle on the right side. There is also a meniscus present, which is generally indicative of fluid.  Chest computed tomography (CT) demonstrated an infiltrate with a mixture of densities within the same collection, consistent with a loculated effusion and concerning for an empyema.

Pediatric Toxic Shock Syndrome

Jennifer Yee, DO* and Andrew King, MD*

DOI: https://doi.org/10.21980/J8WK8J Issue 2:4[mrp_rating_result]
By the end of this simulation session, the learner will be able to: 1) Recognize toxic shock syndrome. 2) Review the importance of a thorough physical exam. 3) Discuss management of toxic shock syndrome, including supportive care and the difference in antibiotic choices for streptococcal and staphylococcal toxic shock syndrome. 4) Appropriately disposition a patient suffering from toxic shock syndrome. 5) Communicate effectively with team members and nursing staff during a resuscitation of a critically ill patient.

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.

Subcutaneous Emphysema in Non-Necrotizing Soft Tissue Injury

Hamid Ehsani-Nia, MS, DO* and Lauren Sylwanowicz MD ^

DOI: https://doi.org/10.21980/J8432M Issue 2:4[mrp_rating_result]
X-Rays of the elbow revealed diffuse striated lucencies throughout the soft tissue, consistent with extensive subcutaneous air throughout the superficial and deep tissues. There was no evidence of a fracture.
