case_images: Ultrasound revealed a cyst on the right side of the neck in the patient at the age of 2 days. The cyst was 2.2 x 1.8 x 2.1 cm in size, and had a wall thickness of 0.2 cm (A). Color Doppler flow imaging (CDFI) showed no obvious blood flow signal on the edge and wall of the capsule (B).

case_images: Color Doppler flow imaging (CDFI) showed no obvious blood flow signal on the edge and wall of the capsule (Figure 1).
case_images: Cervical computed tomography in the patient at the age of 2 days. Coronal and sagittal imaging of cervical computed tomography (CT) revealed that the cyst (2.7 x 1.6 x 1.7 cm) was located in the parapharyngeal space close to the esophagus, and was causing mild compression of the trachea and cervical vessels (A,C). No reinforcement was observed after contrast-enhanced CT scanning (B,D).

case_images: Histological examination of the resected specimen. Histological examination revealed that the cystic wall comprised of smooth muscle, and was lined with colonic mucosal tissue (hematoxylin and eosin [H&E]; x 100 magnification; A,B). The pancreatic components found consisted of acinar cells and ducts in the focal area (H&E; x 100; x 200; C,D).

case_images: Postoperative pathological examinations showed that the cystic wall consisted of smooth muscle and was lined with colonic mucosal tissue, and pancreatic components (acinar cells and ducts) were found in the focal area, and congenital colonic and pancreatic heterotopia were diagnosed and confirmed (Figure 3).
