Radiologic Findings of Single Accessory Splenic Infarction in a Patient with Accessory Spleens in the Abdominal...

Area of Science:

• Abdominal Imaging
• Surgical Pathology
• Gastroenterology

Background:

• Accessory spleens are congenital anomalies, with multiple spleens being rare.
• Accessory spleen infarction is uncommon, usually caused by vascular pedicle torsion.

Observation:

• A 19-year-old male presented with infarction in one of four accessory spleens.
• Imaging diagnosis was difficult; definitive diagnosis required postoperative pathology.
• No evidence of vascular pedicle torsion was found in the infarcted accessory spleen.

Findings:

• The case presented a rare instance of accessory spleen infarction without torsion.
• Postoperative pathology confirmed the diagnosis, challenging initial imaging interpretations.
• The patient recovered well after surgical intervention and conservative management.

Implications:

• Diagnosing accessory splenic infarction without torsion poses significant challenges for imaging modalities.
• A multimodality imaging approach, including diffusion-weighted imaging, may improve diagnostic accuracy.
• This case underscores the importance of integrating imaging findings with pathological results for rare abdominal conditions.
