We report a rare case of an intra-abdominal bronchogenic cyst. An abnormal lesion was detected on an ultrasonogram, done as part of a physical checkup, in an 81-year-old woman. Computed tomography and magnetic resonance imaging showed a cystic mass attached to the lesser curvature of the stomach. Initially, we suspected a congenital cyst without malignant components; however, as the patient wished to have the lesion removed, we performed a minilaparotomy. The cystic lesion was firmly attached to the lesser curvature by fibrous tissue. Microscopic examination subsequently revealed the 26-mm mass to be a benign bronchogenic cyst with a bronchial element. We compared our findings with those of 50 previously reported cases of intraabdominal bronchogenic cysts. None of these patients was older than ours, and lesions attached to the esophagus or stomach were extremely unusual. Bronchogenic cysts are difficult to diagnose preoperatively based on imaging findings, but surgery may be indicated if malignant components are suspected, or if the lesion is enlarging or causing symptoms.
我们报告了一例罕见的腹腔内支气管源性囊肿病例。一位 81 岁女性在体检时超声检查发现异常病变。计算机断层扫描和磁共振成像显示胃小弯附着的囊性肿块。最初，我们怀疑是无恶性成分的先天性囊肿；然而，由于患者希望切除病变，我们进行了小剖腹手术。囊性病变通过纤维组织牢固地附着于小弯。随后的显微镜检查显示，26 毫米大小的肿块为良性支气管源性囊肿，具有支气管成分。我们将我们的发现与之前报道的 50 例腹腔内支气管源性囊肿病例进行了比较。这些患者中没有一个比我们的患者年龄更大，食管或胃附着的病变极为罕见。根据影像学表现，支气管源性囊肿术前难以诊断，但如果怀疑有恶性成分，或者病变增大或引起症状，可能需要手术。
