False cysts have no cellular lining and usually originate from past abdominal trauma. We herein report a 23-year-old woman with an asymptomatic splenic false cyst. She had no history of abdominal trauma. Abdominal computed tomography showed a cystic lesion without internal structure. In contrast, magnetic resonance imaging and ultrasonography revealed an inhomogeneous internal structure without fluid/debris level. Although the images were not typical of a splenic false cyst, the surgically excised mass histologically showed a splenic false cyst (no epithelial element). Non-traumatic splenic false cysts are rare and show nonspecific clinical findings and symptoms. The recommended treatment is splenectomy.
假性囊肿没有细胞衬里，通常源于既往腹部创伤。本文报告 1 例 23 岁女性患者，其为无症状性脾假性囊肿。该患者无腹部创伤史。腹部 CT 显示囊性病变，无内部结构。相比之下，磁共振成像和超声检查显示不均匀的内部结构，无液/碎屑平面。尽管影像学表现不典型，但手术切除的肿块组织学表现为脾假性囊肿（无上皮成分）。非创伤性脾假性囊肿罕见，临床表现和症状无特异性。推荐的治疗方法是脾切除术。
