Summary
Secondary psoas abscesses following spinal fusion are rare but serious infections. Early diagnosis with CT scans and prompt treatment, including surgery and antibiotics, are crucial for patient outcomes.
Area of Science:
- Spinal Surgery
- Infectious Diseases
- Radiology
Background:
- Psoas abscess is a rare clinical condition.
- Often presents with non-specific symptoms, potentially leading to delayed diagnosis.
- Secondary psoas abscesses can occur after anterior spinal fusion.
Observation:
- Three cases of secondary psoas abscess following anterior spinal fusion are presented.
- Computed tomography (CT) is the preferred imaging modality for diagnosis.
- Symptoms may manifest as a late infection post-surgery.
Findings:
- Treatment involves open abscess drainage and antibiotic therapy.
- Addressing the primary infection source, such as deep wound infection after spinal fusion, is essential.
- Predisposing factors include large implants, bone grafting, prolonged surgery, prior spinal procedures, and compromised immunity.
Implications:
- Prompt diagnosis and treatment are critical to reduce morbidity and mortality.
- Surgical intervention may require multiple procedures, including implant removal if stability is maintained.
- Extended antibiotic therapy post-normalization of infection markers is recommended.
