Ectopic splenic tissue in any location could represent accessory spleen, a common congenital abnormality, splenosis, the presence of numerous nodules of ectopic splenic tissue after spleen trauma/surgery or splenogonadal fusion, a rare congenital malformation found mostly in males. Ectopic splenic tissue in the ovary is usually found in the context of an extensive pelvic splenosis. Solitary ovarian splenosis presenting not as a part of pelvic splenosis, but rather as a solitary mass masquerading an ovarian tumor is extremely rare. Differential diagnosis in this case includes mostly splenosis and splenogonadal fusion of the discontinuous type. Relevant literature and possible pathogenesis are discussed.
任何部位的异位脾组织都可能代表副脾，这是一种常见的先天性异常；也可能是脾外伤/手术后或脾性腺融合出现的多发性异位脾组织结节，这是一种罕见的先天性畸形，主要见于男性；或者是卵巢异位脾组织，这种情况通常发生在广泛的盆腔脾组织化生性的背景下。孤立的卵巢脾组织化生而不是作为盆腔脾组织化生性的一部分，而是作为伪装成卵巢肿瘤的单一肿块，极为罕见。这种情况下的鉴别诊断主要包括脾组织化生和不连续型脾性腺融合。本文讨论了相关文献和可能的发病机制。
