The cholecystectomy sonographic pseudolesion

Area of Science:

• Radiology
• Gastroenterology
• Surgical Imaging

Background:

• Post-cholecystectomy patients may present with imaging findings that can be mistaken for pathology.
• The right upper quadrant is a common area for such pseudolesions.

Purpose of the Study:

• To describe a frequent post-cholecystectomy pseudolesion in the right upper quadrant.
• To outline imaging features that distinguish this pseudolesion from true lesions.

Main Methods:

• Review of imaging studies in patients post-cholecystectomy.
• Correlation of imaging findings with clinical data.
• Identification of characteristic features of pseudolesions.

Main Results:

• A specific pseudolesion is frequently identified in the right upper quadrant after gallbladder removal.
• Distinct imaging characteristics differentiate this pseudolesion from true hepatic or biliary lesions.

Conclusions:

• Recognition of this post-cholecystectomy pseudolesion is crucial for accurate diagnosis.
• Understanding these features can prevent unnecessary investigations and interventions.
