Table 2 USG characterization of benign and malignant GB wall thickening
From: Clinical approach to patients with thick wall gallbladder
USG features | Benign | Malignant |
|---|---|---|
Thickening | Diffuse and symmetrical | Focal and asymmetrical |
GB wall layered pattern | Preserved | Absent |
Mucosal continuity | Intact | Breached |
Parenchymal infiltration | Absent | Present |
Color Doppler (Mean & Peak Flow Velocities) | Low | High |
Elastography | Low velocity | High velocity |
Contrast-enhanced US | Homogeneous enhancement Delayed washout | Heterogeneous enhancement Early washout |
