Introduction And Importance:
Iliopsoas abscess is defined as the accumulation of suppurative fluid within the fascia surrounding the psoas and iliac muscles. Although some cases reported psoas abscess due to foreign body, to the best of our knowledge this is the first case of metal shrapnel causing psoas abscess.
Case Presentation:
A 41 years old male presented to our center after a landmine explosion. After a 24-h of monitoring, he was discharged with no complaints. Later he presented with septicemia, antalgic gait, and low back pain. Computed tomography showed right psoas abscess with metal shrapnel inside. By Anterolateral approach, we drained the retroperitoneal abscess and extracted the metal shrapnel. Follow-up for 6 months revealed no recurrence.
Clinical Discussion:
Iliopsoas abscess is one of the challenging cases that urologists face. We presented a patient with penetrating trauma that led to cause psoas abscess. Computed tomography is considered an excellent imaging study to evaluate such patients. Most cases of psoas abscesses treated with antibiotics and minimally invasive drainage. However, with our case, we performed open surgery to extract the metal shrapnel.
Conclusion:
Psoas abscess with metal shrapnel should be treated emergently. Patients with penetrating trauma should be evaluated strictly. Follow-up is essential in patients with a history of landmine explosion. Psoas abscess with metal shrapnel inside should be treated with broad-spectrum antibiotics and open surgery for drainage.
Insights
This case report details the first instance of a psoas abscess caused by metal shrapnel from a landmine explosion. Prompt surgical drainage and antibiotic treatment were crucial for recovery, highlighting the need for strict evaluation after penetrating trauma.
Area of Science:
- Urology
- Trauma Surgery
- Infectious Diseases
Background:
- Iliopsoas abscess involves pus accumulation around the psoas and iliac muscles.
- While foreign bodies can cause these abscesses, metal shrapnel is an unprecedented etiology.
- Penetrating trauma, such as from landmines, presents unique diagnostic and management challenges.
Purpose of the Study:
- To report the first known case of an iliopsoas abscess caused by metal shrapnel.
- To emphasize the importance of thorough evaluation in patients with penetrating trauma.
- To discuss the management of complex iliopsoas abscesses.
Main Methods:
- A 41-year-old male with a history of landmine explosion presented with symptoms of septicemia and low back pain.
- Computed tomography (CT) revealed a right psoas abscess containing metal shrapnel.
- The abscess was drained via an anterolateral approach, and the shrapnel was surgically removed.
Main Results:
- Successful drainage of the retroperitoneal abscess and extraction of the metal shrapnel were achieved.
- The patient experienced no recurrence of the abscess during a 6-month follow-up period.
- Computed tomography proved effective in diagnosing the condition.
Conclusions:
- Psoas abscess secondary to metal shrapnel requires emergent treatment, including broad-spectrum antibiotics and open surgical drainage.
- Patients with penetrating trauma necessitate rigorous evaluation to identify potential complications like abscess formation.
- Close follow-up is vital for individuals with a history of explosive device injuries.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
