The case of a 5-year-old Friesian mare with a mass in her abdomen and a gait irregularity of the left hind limb is discussed. At rectal ultrasonogrphic examination the mass appeared to be a thin-walled, anechogenic cavity in the left abdomen. By means of laparoscopy the mass could be visualized as a smooth structure, covered by peritoneum and fat. Under laparoscopic guidance the mass was punctured and fluid was aspirated. Cytological and bacteriological findings of the fluid were indicative of a cyst. After drainage of the cyst the locomotion disorder of the left hind limb disappeared. It is concluded that this horse suffered from a subperitoneal cyst, a rare disorder in humans and never previously described in horses. The case emphasizes the value of laparoscopy in the diagnosis and treatment of (intra)abdominal masses and further clearly shows that in the differential diagnosis of locomotion disorders not only structures related to the locomotion system should be taken into account.
讨论了一匹5岁弗里斯兰母马的病例，该马腹部有肿块且左后肢步态异常。直肠超声检查时，肿块在左腹部表现为一个薄壁、无回声的腔。通过腹腔镜检查，肿块可被视为一个光滑的结构，被腹膜和脂肪覆盖。在腹腔镜引导下，对肿块进行穿刺并抽吸液体。液体的细胞学和细菌学检查结果表明为囊肿。囊肿引流后，左后肢的运动障碍消失。结论是这匹马患有腹膜下囊肿，这在人类中是一种罕见疾病，此前在马中从未有过描述。该病例强调了腹腔镜检查在诊断和治疗（腹）内肿块方面的价值，并进一步清楚地表明，在运动障碍的鉴别诊断中，不仅应考虑与运动系统相关的结构。
