Giant complex non-parasitic splenic cyst in a young boy: is laparoscopic spleen-preserving surgery safe?

Abstract Non-parasitic splenic cysts are an uncommon finding in pediatric patients. We report on a 14-year-old male presenting with a giant abdominal mass. Imaging documented a giant splenic cyst, and preoperative blood tests revealed high levels of CA125. Minimally invasive unroofing of the cyst was performed. Notably, the cyst content was hematic, but histopathological studies described a mesothelial cyst lining. To date, no recurrence has been noted. Laparoscopic spleen-preserving surgery appears to be a valid and safe treatment option in children with complex non-parasitic splenic cyst to preserve the splenic parenchyma.
