Introduction:
The iliopsoas muscle is a rare place for an abscess to collect. While these abscesses can have high mortality, they are often misdiagnosed. The use of point-of-care ultrasound (POCUS) can aid in earlier diagnosis.
Case Report:
A 45-year-old male presented to the emergency department (ED) with severe lower back pain. The pain radiated to both of his legs and was associated with fever, weight loss, and malaise. The differential diagnosis for this patient was broad. A POCUS was performed at the bedside and revealed bilateral iliopsoas abscesses. This finding was then confirmed by computed tomography.
Conclusion:
In this case report we will discuss how to identify an iliopsoas abscess using POCUS in ED patients, and the utility of POCUS to facilitate an expedited diagnosis.
Insights
Point-of-care ultrasound (POCUS) aids in early diagnosis of rare iliopsoas abscesses. This imaging technique can expedite identification in emergency department patients, potentially reducing mortality.
Area of Science:
- Emergency Medicine
- Radiology
- Infectious Disease
Background:
- Iliopsoas muscle abscesses are uncommon but carry high mortality.
- These abscesses are frequently misdiagnosed due to non-specific symptoms.
- Early diagnosis is critical for effective management and improved patient outcomes.
Purpose of the Study:
- To highlight the utility of point-of-care ultrasound (POCUS) in diagnosing iliopsoas abscesses.
- To demonstrate how POCUS can facilitate expedited diagnosis in the emergency department.
- To discuss the identification of iliopsoas abscesses using POCUS.
Main Methods:
- A case report of a 45-year-old male presenting with severe lower back pain and systemic symptoms.
- Point-of-care ultrasound (POCUS) performed at the bedside.
- Computed tomography (CT) scan to confirm POCUS findings.
Main Results:
- POCUS revealed bilateral iliopsoas abscesses in the emergency department.
- CT confirmed the presence of bilateral iliopsoas abscesses.
- The patient's presentation included fever, weight loss, and malaise.
Conclusions:
- POCUS is a valuable tool for the early detection of iliopsoas abscesses.
- Bedside ultrasound can expedite diagnosis and treatment initiation for iliopsoas abscesses.
- Integrating POCUS into emergency department protocols can improve outcomes for patients with suspected iliopsoas abscess.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
