Description
Ryo Ichibayashi, Manami Oki, and Takashi Ishii report a scanning pitfall in a 2025 case. An older woman came to a clinic with nausea and fever. Ultrasound seemed to show a large pool of free fluid in her belly. Free fluid, called ascites, can signal serious gut or pelvic disease.
She was sent to an emergency department for more checks. Repeat ultrasound found no fluid in the low spots where it settles first. Those spots lie by the liver and behind the uterus. A CT scan then revealed the true cause of the image. A giant kidney cyst had mimicked free fluid on the first scan. The fever traced instead to pneumonia near a hernia. The authors stress checking gravity-dependent areas when ascites is suspected. Absent fluid there should prompt a second look and more imaging.
