Diagnosis of gastric duplication cyst by positron emission tomography/computed tomography: A case report

Abstract

BACKGROUNDGastric 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 SUMMARYA 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.CONCLUSIONPreoperative 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.

Uncommon Presentation of Gastric Duplication Cyst with Left-Sided Portal Hypertension: A Case Report and Literature Review

“…There is a higher risk of confusion with the latter method, and the challenge arises from the difficulty in discerning between cystic formations with varying contents. On the other hand, this does not seem to be the case for F-FDG-PET/CT [26]. Mohamad Abdalkader et al presented the case of a 28-year-old adult who reported persistent abdominal pain and nausea [18].…”

Computed tomography features and clinical characteristics of gastritis cystica profunda

“…The gases and liquids are observed in the gastric cavity, indicating that the opening of the diverticulum is connected with the gastric cavity. Gastric duplication cyst is an extremely uncommon lesion, which is common in infants and sometimes accompanied by other malformations [ 37 ]. Ménétrier disease usually presents with thickened gastric folds, but without cystic changes.…”

Quiste de duplicación gástrico en paciente adulto: Reporte de caso y revisión de la literatura

“…En la paciente presentada, de acuerdo con los hallazgos ecográficos iniciales, se realizó una tomografía computarizada de abdomen, para caracterizar mejor la lesión, con la presunción de un tumor del estroma gastrointestinal versus una neoplasia maligna de origen epitelial como diagnóstico diferencial. En relación con el diagnóstico, la literatura reporta mayor rendimiento de métodos como biopsia por aspiración con aguja fina guiada por endoscopia o endosonografía, y la tomografía por emisión de positrones (PET-CT), en comparación con la tomografía computarizada o la resonancia magnética nuclear 13,18,19 . En este caso no se consideró la realización de PET-CT o la biopsia por endosonografía debido a que estas opciones no están disponibles en nuestro medio, no existe evidencia que apoye su uso, su costo es elevado y no afectaba la decisión del manejo quirúrgico.…”
