Peritoneal abscess

Description

Peritoneal abscesses are localized pus collections in the peritoneal cavity, potentially life-threatening if not promptly treated. They stem from various conditions like post-surgical complications and intra-abdominal infections. Diagnosis now relies on advanced imaging alongside clinical evaluation, with ultrasound being a valuable tool.
