Radiologic Findings of Single Accessory Splenic Infarction in a Patient with Accessory Spleens in the Abdominal Cavity: A Case Report

Abstract

The presence of multiple accessory spleens in the abdominal cavity is typically limited to two, with cases involving a higher number being exceedingly rare. Concurrently, accessory spleen infarction is remarkably uncommon, primarily resulting from torsion of the vascular pedicle. In this report, we present a case of a 19-year-old male who experienced infarction in one of four accessory spleens. Imaging diagnosis proved challenging, with the definitive diagnosis being made through postoperative pathology, revealing no torsion in the affected accessory spleen. Following surgery combined with anti-inflammatory and analgesic treatment, the patient exhibited an uneventful recovery. No complications were observed at the 3-month follow-up. This case indicates the challenge and difficulty of diagnosing accessory splenic infarction without torsion in imaging diagnosis. Employing a multimodality approach and diffusion-weighted imaging may aid in confirming the diagnosis.

Case Report: Severe intermittent acute abdominal pain caused by extremely rare case of lienorenal accessory spleen torsion and detorsion: an accurate diagnostic and treatment strategy

“…Laparoscopy surgery is proven to be able to effectively excise the accessory spleen, and even the patient can do outpatient care one day after surgery. 13 Besides of good diagnosis strategy, an appropriate treatment strategy is needed. modified anti-Trendelenburg 3-port laparoscopic excision of the accessory spleen (LEAS) could be the best option to evacuate the accessory spleen.…”
