Summary
A rare gallbladder cystadenoma caused obstructive jaundice by pressing on the common bile duct (CBD). This first-of-its-kind case highlights a unique gallbladder lesion.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Hepatobiliary Surgery
Background:
- Obstructive jaundice can arise from various biliary pathologies.
- Gallbladder masses are uncommon causes of common bile duct (CBD) compression.
Observation:
- A patient presented with obstructive jaundice attributed to extrinsic pressure on the CBD.
- Imaging revealed a dilated CBD, massively dilated gallbladder, and a multiseptated cystic structure in the gallbladder fossa.
Findings:
- Histological examination of the surgical specimen confirmed a multilocular cyst lined with biliary-type epithelium.
- The cyst walls showed fibromuscular proliferation.
- This gallbladder lesion was not found in existing literature.
Implications:
- This case represents the first documented instance of gallbladder cystadenoma.
- It expands the differential diagnosis for extrinsic CBD compression and gallbladder masses.
- Highlights the importance of thorough histopathological evaluation for rare biliary tract lesions.
