Brunner's gland hamartoma is an uncommon intestinal tumor, most frequently located in the duodenal bulb. We report the endoscopic sonographic (EUS) appearances in 2 cases of Brunner's gland hamartoma. In 1 case, EUS revealed a heterogeneous hypoechoic pedunculated mass, 1.7 cm in diameter, arising from the mucosal and submucosal layers of the wall of the duodenal bulb. Multiple anechoic large and small cystic areas were demonstrated in the tumor. In the other case, EUS revealed a 1.4- x 0.9-cm pedunculated mass with an echogenicity higher than that of the muscular layer and lower than that of the mucosa, arising from the submucosal layer of the duodenal bulb wall. Multiple small anechoic areas were demonstrated in the tumor. We believe that both EUS patterns are typical for Brunner's gland hamartomas.
布伦纳腺错构瘤是一种罕见的肠道肿瘤，最常位于十二指肠球部。我们报告2例布伦纳腺错构瘤的内镜超声（EUS）表现。1例中，EUS显示一个直径1.7 cm的异质性低回声带蒂肿块，起源于十二指肠球部肠壁的黏膜层和黏膜下层。肿瘤内可见多个大小不等的无回声囊性区。另1例中，EUS显示一个1.4×0.9 cm的带蒂肿块，其回声高于肌层但低于黏膜，起源于十二指肠球部肠壁的黏膜下层。肿瘤内可见多个小的无回声区。我们认为这两种EUS表现均为布伦纳腺错构瘤的典型表现。
