[Benign non-parasitic splenic cysts. 9 cases]

Benign non-parasitic splenic cysts are uncommon. Their diagnosis can benefit from ultrasounds and computed tomography. However, it may be difficult, before surgery, to distinguish between true cysts, which are congenital with epidermal lining, and false cysts, which are consecutive to a trauma, inflammatory or degenerative, without epidermal lining. We report nine cases of non-parasitic splenic cysts and try to determine the preoperative diagnostic approach. To prevent the overwhelming post-splenectomy infection syndrome, conservative surgical treatment is mandatory. Various surgical methods are discussed.
