Summary
A rare late complication of appendicitis, a psoas abscess, was diagnosed in a patient 4 years after appendectomy. This case highlights the importance of considering appendicitis sequelae in unusual presentations.
Area of Science:
- Infectious Diseases
- Surgical Complications
- Abdominal Imaging
Background:
- Psoas abscesses are typically linked to adjacent infections.
- Late-onset psoas abscesses following acute appendicitis are exceptionally rare.
- The exact relationship between appendicitis, appendectomy, and subsequent psoas abscess remains debated.
Observation:
- A 25-year-old male presented with fever and right lower quadrant pain.
- A history of acute appendicitis and complicated appendectomy 4 years prior was noted.
- Abdominopelvic CT revealed a large right psoas abscess extending into adjacent muscles.
Findings:
- The patient had fever, abdominal tenderness, and leukocytosis.
- Imaging confirmed a 6 cm hypodense mass within the right psoas muscle.
- Percutaneous drainage and broad-spectrum antibiotics were initiated.
Implications:
- This case underscores the potential for delayed complications after appendectomy.
- It suggests a possible, though rare, link between appendicitis sequelae and psoas abscess formation.
- Further investigation may be warranted to elucidate the pathophysiology of late-onset abscesses post-appendicitis.
