Retroperitoneal non-pancreatic or idiopathic pseudocysts are very rare lesions. This case report aimed to present our patient and to check all the available literature on this kind of rare disease.
Our patient was a 67-year-old Iranian man admitted with mild abdominal discomfort for three months. Ultrasonography and CT scan revealed a huge cystic structure within the retroperitoneal space. The lesion was excised through midline laparotomy and opening of the retro-peritoneum. The histopathology of the cyst wall revealed a benign cystic lesion with no epithelial lining. A histologic diagnosis of non-neoplastic retroperitoneal pseudocyst was made.
The primary non-pancreatic retroperitoneal pseudocysts are rare lesions and have to be distinguished from other differential diagnoses of retroperitoneal lesions, and a surgeon should be aware of the possible occurrence of these lesions with unknown origin. Surgical excision is the only way to exclude malignancy and confirm the diagnosis.
腹膜后非胰腺性或特发性假性囊肿是非常罕见的病变。本病例报告旨在介绍我们的患者，并查阅关于这种罕见疾病的所有可用文献。
我们的患者是一名 67 岁的伊朗男性，因三个月来轻度腹部不适入院。超声和 CT 扫描显示腹膜后间隙有一个巨大的囊性结构。通过正中剖腹术和腹膜后切开术切除病变。囊壁的组织病理学显示为无上皮衬里的良性囊性病变。组织学诊断为非肿瘤性腹膜后假性囊肿。
原发性非胰腺性腹膜后假性囊肿是罕见病变，必须与腹膜后病变的其他鉴别诊断区分开来，外科医生应该意识到可能发生这些来源不明的病变。手术切除是排除恶性肿瘤和明确诊断的唯一方法。
