Chronic gallbladder wall thickening: Is it always malignancy?

Area of Science:

• Gastroenterology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Gallbladder wall thickening can indicate malignancy.
• Features like perforation and fistula formation are often associated with gallbladder cancer.
• Differentiating benign from malignant causes is critical for patient management.

Observation:

• Xanthogranulomatous cholecystitis (XGC) presents with gallbladder wall thickening.
• XGC shares aggressive clinical, radiological, and surgical features with gallbladder carcinoma.
• This case involved chronic gallbladder wall thickening initially suspected to be malignant.

Findings:

• The patient's condition, initially suspected as gallbladder cancer, was ultimately diagnosed as Xanthogranulomatous cholecystitis (XGC).
• This highlights the challenge in distinguishing XGC from gallbladder carcinoma based on imaging and clinical presentation alone.
• Histopathological examination is crucial for definitive diagnosis.

Implications:

• Misdiagnosis of gallbladder cancer can lead to inappropriate radical surgical interventions.
• Recognizing XGC avoids unnecessary aggressive treatment for a benign condition.
• Improved diagnostic criteria and awareness are needed to differentiate XGC from gallbladder malignancy.
