Acute cholecystitis 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.

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:

Chronic cholecystitis - has less inflammation, fibrotic wall thickening/muscular hypertrophy, may have RK sinuses.
Gallbladder adenocarcinoma.
Intestinal metaplasia of the gallbladder.

Special types

Gangrenous cholecystitis

General:^[7]

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

Microscopic:

Necrosis of gallbladder wall (muscularis propria).^[8]

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