Primary retroperitoneal serous cystadenomas (PRSCs) are rare cystic lesions whose pathogenesis is currently not well understood. Although the vast majority of tumors are benign, early recognition and resection is necessary to avoid malignant transformation, rupture, and secondary infection. Here we present the case of a 79-year-old woman who presented with confusion, visual hallucinations, and a history of fall. As part of the work-up for abdominal distension, computed tomography scan of the abdomen and pelvis was performed, which revealed a right-sided retroperitoneal cystic lesion measuring 26.6 × 16.7 cm in size. The lesion was resected laparoscopically, and the surgical specimen measured 28 × 17 cm. Histology revealed a serous cystadenoma. The postsurgical course was uneventful, and no radiological recurrence was noted on 3 months follow-up. Very few primary retroperitoneal cystic lesions have been reported in the literature. Most lesions are benign and predominantly occur in females. They may remain asymptomatic for long periods of time and are usually discovered when they reach very large in size. In rare cases, these lesions may have malignant potential. Diagnosis of PRSC should be considered in the differential diagnosis of all retroperitoneal cysts.
原发性腹膜后浆液性囊腺瘤（PRSCs）是一种罕见的囊性病变，其发病机制目前尚不清楚。尽管绝大多数肿瘤是良性的，但为避免恶变、破裂及继发感染，早期识别和切除是必要的。在此，我们报告一例79岁女性病例，该患者出现意识模糊、视幻觉及跌倒史。作为腹胀检查的一部分，进行了腹部和盆腔的计算机断层扫描，结果显示右侧腹膜后有一个大小为26.6×16.7 cm的囊性病变。该病变通过腹腔镜手术切除，手术标本大小为28×17 cm。组织学检查显示为浆液性囊腺瘤。术后过程顺利，3个月随访未发现影像学复发。文献中报道的原发性腹膜后囊性病变非常少。大多数病变是良性的，主要发生在女性。它们可能长期无症状，通常在体积非常大时才被发现。在罕见情况下，这些病变可能具有恶变潜能。在所有腹膜后囊肿的鉴别诊断中均应考虑PRSC的诊断。
