Sonography of gallbladder duplication and differential considerations

Summary
Gallbladder duplication, a rare condition, can be mistaken for other diseases. Sonography can help identify this anomaly, with non-contracting lobes suggesting a double gallbladder.
Area of Science:
- Medical imaging
- Gastroenterology
- Surgical pathology
Background:
- Routine sonography is crucial for diagnosing gallbladder disease.
- Familiarity with gallbladder duplication and its differentials is essential for accurate diagnosis.
Observation:
- Three cases of suspected gallbladder duplication are presented.
- One case involved surgically proven gallbladder duplication.
- Another case showed sonographic findings consistent with duplication, and a third had an intraperitoneal fibrous band mimicking duplication.
Findings:
- Gallstones were present in all cases, confined to a single lobe.
- Gallstones did not communicate between lobes, even with positional changes.
- Contraction of a non-stone-containing lobe in a nonfasting patient served as an indirect sign of double gallbladder.
Implications:
- Accurate sonographic identification of gallbladder duplication is important to avoid misdiagnosis.
- Understanding differential diagnoses, such as fibrous bands, is critical.
- Recognizing indirect signs like differential lobe contraction aids in diagnosing this rare anomaly.
