ABSTRACT
Introduction: The prenatal detection of an intrathoracic cyst during the first trimester of pregnancy is an exceedingly rare condition. In this report, we describe a case of first-trimester intrathoracic cyst causing cardiac dextroposition, which resolved by 24 weeks' gestation. Case report: A 5-mm intrathoracic cyst causing cardiac dextroposition was detected during the routine sonographic scan performed at 12 weeks + 2 days. The cyst remained stable in size until 20 weeks and was no longer identified during focused fetal echocardiography at 24 weeks. Discussion: Our case demonstrates that a first-trimester intrathoracic cyst can have a benign course, either by remaining stable in size or even undergoing complete resolution during the second trimester. A focused sonographic examination should therefore be undertaken as follow-up to determine the final prognosis of these lesions. Conclusion: The etiology of intrathoracic cysts detected in the first trimester is unclear and could represent a resolving pericardial cyst.
ABSTRACT
The existence of a cystic mass which walls originated from a metastatic gallbladder adenocarcinoma is infrequent. We present the case of 68-year-old male that present to the emergency department with abdominal distention, hyporexia and jaundice. Upon exploratory laparotomy, a duodeno-colonic cyst with walls formed by metastatic cells derived from a Gallbladder Adenocarcinoma. Metastatic disease from a gallbladder adenocarcinoma to transverse colon and duodenum formed adherences between both organs, leading to the formation of cystic mass. Cancer cells have multiple adaptation mechanisms in order to survive harsh environments.
La existencia de un quiste cuyas paredes se originaron de una metástasis de adenocarcinoma de vesícula biliar es infrecuente. Varón de 68 años con distensión abdominal, hiporexia e ictericia. En la laparotomía exploratoria se evidencia un quiste duodeno-colónico de paredes conformadas por células metastásicas producto de un adenocarcinoma de vesícula biliar. La metástasis del adenocarcinoma de vesícula biliar hacia colon transverso y duodeno formaron adherencias entre ambos órganos, conduciendo a la formación de una masa quística. Las células cancerígenas pueden adaptarse de muchas maneras para sobrevivir en entornos adversos.
