Perigastric appendgitis is a rare inflammatory/ischemic process involving the perigastric ligaments (gastrohepatic, gastrospleic and falciform ligaments).

Epiploic appendagitis, greater omental infarction, and perigastric appendagitis have similar mechanisms, clinical presentations, and radiological appearances.

Clinical presentation

Acute and severe abdominal (epigastric) pain in absence of fever.

Pathology

Peritoneal ligaments contain uneven quantities of extraperitoneal fat.

Similar to epiploic appendagitis and greater omental infarction, perigastric appendagitis occurs when perigastric ligament appendages spontaneously twist causing vascular compromise and infarction.

Radiographic features

CT

CT appearances consist of:

oval heterogeneous fat density focus with mild surrounding fat stranding along the course of the gastrohepatic (anterior to the stomach), gastrosplenic (posterior to the stomach), and falciform (anterior to the liver) ligaments
