Case report: imaging of a bilobed gallbladder

Occurrence and clinical significance of abnormal liver findings by ultrasound in captive owl monkeys

BACKGROUND

Imaging diagnostic methods are essential for a complete understanding of the liver function and may aid in early detection of hepatic disorders.

METHODS

Sixty-nine owl monkeys were grouped in three age groups (AG): AG1 (<2 years old, n = 14), 2 (2-6 years old, n = 21), and 3 (>7 years old, n = 34). The animals were evaluated by ultrasound, liver function tests, and hemogram.

RESULTS

The ultrasound revealed abnormal findings in the parenchyma ("starry sky" and steatosis) and/or in the gallbladder (cholelithiasis, septum, and wall edema) in 17 individuals, with higher incidence in AG3 individuals. Seven hepatic individuals showed alterations in the blood tests.

CONCLUSION

Our study reported the occurrence of abnormal liver findings by ultrasound in owl monkeys and their associated clinical analyses. We recommend the regular use of ultrasound to evaluate liver condition in owl monkeys, particularly in old individuals.

Bilobed gallbladder diagnosed by oral cholecysto-CT

Morphological anomalies of the gallbladder are rare and are characterized by a large variety of configurations depending on the size and degree of fusion of the lobes, and on the number and position of the cystic ducts. We presented a case of bilobed gallbladder incidentally detected during abdominal ultrasonography. Oral cholecystography and computed tomographic examination after oral cholecystography (Oral Cholecysto-CT) were performed to confirm this abnormality. This is a quite rare anomaly consisted of complete duplication of the fundus and partially duplication of the corpus and separated lobes both of which entered a single infundibulum and cystic duct.
