Acalculous Cholecystitis in Four Canine Cases: Ultrasonographic Findings and Use of Ultrasonographic-Guided, Percutaneous Cholecystocentesis in Diagnosis

Canine cholecystitis is diagnosed infrequently. Clinical signs, physical examination findings, and clinicopathological abnormalities are nonspecific. Few reports exist of associated ultrasonographic findings which also are nonspecific for the disorder. Ultrasonographic-guided, percutaneous cholecystocentesis has been suggested for diagnostic confirmation. The present report further documents ultrasonographic findings associated with canine acalculous cholecystitis and demonstrates the utility of ultrasonographic-guided, percutaneous cholecystocentesis in confirmation of the diagnosis in a prospectively acquired clinical case series.
