Cystic lymphangiomas are uncommon benign lesions extremely rare in the adult population. Most cases are found in the neck and axillary regions; while <1% of patients present with cystic lymphangiomas in the mesentery, greater omentum and retroperitoneum. The present report describes a rare case of large omental lymphangioma mimicking ovarian mass. A 40-year-old G2P2 female patient presented without symptoms for routine gynecological examination. Transvaginal ultrasound examination revealed a cystic mass with a maximum diameter of 10 cm localized at the right parametrium space, suggestive of large cystic lesion of the right ovary. Further preoperative evaluation by magnetic resonance imaging indicated that the mass was either cystic lymphangioma or mesenteric cyst. Complete excision of the cyst without need for gastrectomy was performed via laparotomy under general anaesthesia. Histology revealed omental lymphangioma. Most abdominal lymphangiomas are initially asymptomatic. The role of synchronous imaging examinations, such as ultrasonography and magnetic resonance imaging, in diagnosis of these lesions is crucial. Full preoperative differential diagnosis evaluation in cases of large intraabdominal lesions is required in order to decide the appropriate surgical approach and management.
囊性淋巴管瘤是一种罕见的良性病变，在成人中极为罕见。大多数病例见于颈部和腋窝区域；而肠系膜、大网膜和腹膜后出现囊性淋巴管瘤的患者不到1%。本报告描述了一例罕见的大网膜淋巴管瘤，酷似卵巢肿块。一名40岁、孕2产2的女性患者因无症状前来进行常规妇科检查。经阴道超声检查发现一个最大直径为10 cm的囊性肿块，位于右侧子宫旁间隙，提示右侧卵巢有大的囊性病变。术前进一步通过磁共振成像评估表明，该肿块要么是囊性淋巴管瘤，要么是肠系膜囊肿。在全身麻醉下通过剖腹手术完整切除囊肿，无需进行胃切除术。组织学检查显示为大网膜淋巴管瘤。大多数腹部淋巴管瘤最初无症状。同步成像检查，如超声检查和磁共振成像，在这些病变的诊断中起着至关重要的作用。对于腹部大病变病例，术前需要进行全面的鉴别诊断评估，以决定合适的手术方法和治疗方案。
