Ultrasound and Imaging Findings of Splenic Littoral Cell Angioma in a Child: A Case Report

Splenic littoral cell angioma (LCA) is a rare vascular tumor arising from littoral cells in the splenic red pulp, predominantly affecting adults, with pediatric cases exceedingly rare. An 8‐year‐old girl was admitted after an incidental left abdominal mass discovery. Ultrasonography revealed a slightly hyperechoic splenic mass (75 × 70 × 70 mm). Contrast‐enhanced computed tomography and magnetic resonance imaging demonstrated persistent heterogeneous enhancement, suggesting a benign vascular tumor. Laparoscopic partial splenectomy was performed, and pathology confirmed LCA. At 29‐month follow‐up, no recurrence or metastasis was evident. Multimodal imaging and intraoperative ultrasound‐guided partial splenectomy proved valuable for diagnosis and spleen‐preserving management.
