The findings are in keeping with infarction of a fatty appendage of the falciform ligament, an entity falling within the umbrella term of "intraperitoneal focal fat infarction" or IFFI. Other and more common types of IFFI include epiploic appendagitis and omental infarction. The diagnosis is important to make accurately as management is usually conservative. CT is the key diagnostic tool as it excludes other more serious pathology such as visceral perforation.
