A pericardial cyst was incidentally discovered in a 53-year-old woman after a routine abdominal ultrasound suggested thoracic fluid accumulation, which was confirmed by CT and MRI.
Highlights the potential for incidental discovery of thoracic abnormalities such as pericardial cysts during routine abdominal ultrasound.
ABSTRACT During a routine health check‐up, a 53‐year‐old woman underwent an abdominal ultrasound, suggesting the presence of fluid accumulation within the thoracic cavity. For further evaluation, chest computed tomography and magnetic resonance imaging were performed, revealing a cystic lesion, which was diagnosed as a pericardial cyst.
Yasuhito Sekimoto (2026) studied this question. A pericardial cyst was incidentally discovered in a 53-year-old woman after a routine abdominal ultrasound suggested thoracic fluid accumulation, which was confirmed by CT and MRI.
