Sonography of the accessory spleen
AJR. American Journal of Roentgenology
|July 1, 1984
Summary
Sonography effectively identifies accessory spleens, which appear as round or oval solid masses similar to the main spleen. This imaging technique aids in preoperative detection and localization for potential splenectomy in hematologic conditions.
Area of Science:
- Radiology
- Medical Imaging
- Abdominal Imaging
Background:
- Accessory spleens are congenital anomalies, often asymptomatic.
- Preoperative identification is crucial for patients undergoing splenectomy for hematologic disorders.
Purpose of the Study:
- To describe the sonographic features of accessory spleens.
- To evaluate the diagnostic utility of sonography in detecting and localizing accessory spleens.
Main Methods:
- Retrospective analysis of sonographic findings in 19 patients with 20 accessory spleens.
- Detailed assessment of size, shape, echogenicity, and vascularity of accessory spleens.
Main Results:
- Accessory spleens presented as round/oval solid structures with echogenicity similar to the main spleen.
- High-amplitude interfaces surrounded accessory spleens, differentiating them from adjacent organs.
- Sonographic demonstration of vascular supply from the splenic artery/vein was diagnostic in 90% of cases.
Conclusions:
- Sonography is a valuable tool for preoperative detection and localization of accessory spleens.
- Understanding sonographic characteristics aids in surgical planning for patients requiring splenectomy.
