Acute cholecystitis, abbreviated AC, is a relatively uncommon gallbladder pathology when compared to chronic cholecystitis. It is usually associated with gallstones and seen in older individuals.

General

  • Less common than chronic cholecystitis.
  • Usually due to gallstones.[1]
  • Classically older individuals (50s and 60s) with a slight female predominance.[1]

Notes:

  • Pathologic diagnosis very often discordant with clinical impression.[2]

Gross

Features:[1]

  • Wall thickening - due to edema and hemorrhage.†
  • Gallstone(s) - classically obstructing the gallbladder neck.
  • +/-Mucosal erosions.

Note:

  • † The sonographic criterium for "thick" is greater than 3 mm.[3][4]

Microscopic

Features:[1]

  • Edema.
  • Hemorrhage.
  • +/-Fibrin thrombi in small veins.
  • +/-Mucosal erosions.
  • +/-Neutrophils - useful
    • Not essential for the Dx of acute cholecystitis.
    • Neutrophils usually secondary to necrosis/ulceration or infection.[5]
  • +/-Reactive epithelial changes.[6]

Notes:

  • May see activated fibroblasts.

DDx:

Special types

Gangrenous cholecystitis

General:[7]

  • Older.
  • Clinically "sicker".
  • Worse outcome than (acute) non-gangrenous cholecystitis.

Micro

The sections show gallbladder wall with hemorrhage, and activated fibroblasts. The superficial mucosa has clusters of neutrophils.

Alternate

The sections show an inflamed gallbladder wall with hemorrhage, activated fibroblasts and focal necrosis. The mucosa is partially eroded. Abundant neutrophils and eosinophils are present. No significant nuclear changes are apparent.
