Summary
Ectopic liver, a rare condition, can occur outside the main liver. This case highlights its unusual gallbladder location, diagnosed via imaging and confirmed by surgery.
Area of Science:
- Surgical pathology
- Embryology
- Gastrointestinal surgery
Background:
- Ectopic liver is a rare congenital anomaly resulting from aberrant liver tissue development during embryogenesis.
- It is infrequently documented in surgical literature and often discovered incidentally during procedures for other conditions, particularly biliary tract diseases.
Observation:
- A 3.7-cm mass was identified adjacent to the gallbladder fundus.
- Preoperative computed tomography (CT) visualized the mass, raising suspicion for an unusual lesion.
- The mass was located in an atypical intraperitoneal site, associated with the gallbladder.
Findings:
- Diagnostic laparoscopy confirmed the presence of the mass.
- Histological examination post-cholecystectomy with en bloc resection identified the mass as ectopic liver tissue.
- The ectopic liver was found attached to the gallbladder fundus, a rare presentation.
Implications:
- This case expands the known anatomical variations of ectopic liver presentation.
- Highlights the importance of comprehensive preoperative imaging in identifying rare surgical pathologies.
- Underscores the need for surgical awareness of ectopic liver, even when presenting incidentally with common gallbladder disease.
