Agenesis of the gallbladder.

Area of Science:

• Gastroenterology and Hepatobiliary Surgery
• Congenital Anomalies
• Diagnostic Imaging

Background:

• Gallbladder agenesis is a rare congenital anomaly with variable clinical presentations.
• Preoperative diagnosis can be challenging, particularly when associated with other biliary tract abnormalities.
• Symptoms may mimic common biliary disorders such as cholelithiasis.

Observation:

• This case highlights the diagnostic difficulties of gallbladder agenesis when a dysplastic cyst is present.
• The dysplastic cyst can simulate the gallbladder, complicating preoperative assessment.
• Surgical intervention is often necessary for definitive diagnosis and management.

Findings:

• Gallbladder agenesis associated with a dysplastic cyst presents a unique diagnostic challenge.
• Open surgery, careful common bile duct dissection, and intraoperative imaging are crucial for confirmation.
• Associated anomalies must be excluded during surgical exploration.

Implications:

• Accurate diagnosis and management of gallbladder agenesis are essential to prevent complications.
• Surgical planning must account for potential associated anomalies and the need for precise dissection.
• This case underscores the importance of advanced imaging and surgical techniques in managing rare biliary tract anomalies.
