Clinical Report: Case Study of Isolated Littoral Cell Angioma of the Spleen
Overview
This report details a case of isolated splenic littoral cell angioma (LCA) in a 9-year-old male, diagnosed after incidental discovery during a physical examination. Surgical resection was performed, and no recurrence was noted at follow-up.
Background
Littoral cell angioma is a rare primary vascular tumor of the spleen, particularly uncommon in pediatric patients. Most cases are asymptomatic and diagnosed incidentally, leading to potential misdiagnosis. Understanding the clinical and imaging characteristics of LCA is crucial for accurate diagnosis and management.

Key Findings
Isolated LCA is rare in pediatric patients, with most cases being asymptomatic.
The tumor was confirmed through pathological examination and immunohistochemistry.
CT imaging showed characteristic enhancement patterns, aiding in diagnosis.
Surgical resection resulted in no recurrence at 3 and 6 months postoperatively.
Definitive diagnosis relies on pathology, highlighting the importance of surgical intervention.
Clinical Implications
Healthcare professionals should consider LCA in differential diagnoses for splenic lesions in children, especially when imaging shows characteristic enhancement patterns. Surgical resection remains the primary treatment approach.
Conclusion
This case emphasizes the importance of recognizing isolated LCA in pediatric patients and the role of imaging and pathology in diagnosis and management.
