Abstract
BACKGROUND

Gastric duplication cysts (GDCs) are extremely uncommon lesions and the definitive diagnosis of GDCs is challenging for gastrointestinal specialists. It is important that a differential diagnosis is performed to rule out the possibility of other diseases, mainly malignancies with a cystic component. Despite the use of multiple diagnostic modalities including endoscopy, the preoperative diagnosis of GDCs is challenging.

CASE SUMMARY

A 53-year-old female patient with a GDC was confirmed by positron emission tomography/computed tomography (PET/CT) instead of more conventional procedures such as endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). We propose that 18F-FDG-PET/CT has higher accuracy than EUS-FNA and may be an effective technique for the characterization of duplication cysts.

CONCLUSION

Preoperative diagnosis of GDCs in adults is difficult largely due to their rarity and the absence of characteristic findings. In addition, few endoscopists include GDCs in the differential diagnosis when they encounter a lesion with cystic characteristics. 18F-FDG-PET/CT with additional imaging data, may complement EUS-FNA in the diagnosis of GDCs.

Core tip: Gastric duplication cysts (GDCs) are rare congenital gastrointestinal abnormalities. This is the first case report in which both endoscopic ultrasonography-guided fine needle aspiration and positron emission tomography/computed tomography approaches were used in the diagnosis and intervention of GDCs. Even though a panel of imaging modalities is available to consolidate the diagnosis, it is still recommended that a different operative approach to resect the cystic lesion is chosen, as most cases with symptomatic manifestations and/or complications have the possibility of malignant transformation at the time of presentation.
