INTRODUCTION The splenic lesions that have cystic presentation include a range of disorders. We discuss these non-parasitic ones, which are: the primary or true cysts (epithelial, epidermoid), pseudocysts (serous or hemorrhagic), vascular cysts (post-infarction, peliosis) and cystic neoplasms (hemangioma, lymphangioma, lymphoma and metastases). Splenic cysts are more frequent in the second and third decades of life, but they may appear in other age groups1,2. In 1829, Andral was responsible for the first description of a non-parasitic cyst of the spleen3. Robbins (1978) reviewed a series of 42,327 autopsies over 25 years, founding 32 patients with splenic cysts. Subsequently, isolated cases have been reported and, in 1978, approximately 600 cases were confirmed in the literature4,5. Splenic anatomy and physiology The splenic size and configuration vary. Typical parameters include dimensions of 12 x 7 x 4 cm and a weight of 150 grams (range 100-200 grams) and an anatomic rela...
