CT of a thickened-wall gall bladder

Area of Science:

• Radiology
• Medical Imaging
• Gastroenterology

Background:

• Gallbladder wall thickening is a common finding on computed tomography (CT) scans.
• It can be indicative of a wide range of pathological conditions, from benign inflammation to malignancy.
• Accurate interpretation is crucial for appropriate patient management.

Purpose of the Study:

• To review the diverse clinical conditions presenting as gallbladder mural thickening on contrast-enhanced CT.
• To provide a comprehensive visual guide for radiologists and clinicians.
• To correlate imaging findings with underlying pathologies.

Main Methods:

• Retrospective review of contrast-enhanced CT examinations demonstrating gallbladder mural thickening.
• Categorization of findings based on etiology (e.g., inflammatory, neoplastic, systemic).
• Correlation with histopathological data where available.

Main Results:

• Identification of key imaging features distinguishing various causes of gallbladder wall thickening.
• Examples include acute cholecystitis, chronic cholecystitis, gallbladder carcinoma, and extrinsic compression.
• Discussion of less common but important differential diagnoses.

Conclusions:

• Contrast-enhanced CT is a valuable tool for evaluating gallbladder mural thickening.
• Recognizing specific imaging patterns aids in differentiating benign from malignant processes.
• A systematic approach facilitates accurate diagnosis and guides further clinical decisions.
