CT findings in Mirizzi syndrome

Area of Science:

• Radiology
• Gastroenterology
• Surgical Pathology

Background:

• Mirizzi syndrome is a rare condition caused by impacted gallstones in the cystic duct or gallbladder neck.
• It can lead to biliary obstruction and complications if not diagnosed accurately.

Observation:

• Computed tomography (CT) was used to study six cases of Mirizzi syndrome.
• The study focused on identifying characteristic imaging findings suggestive of the condition.

Findings:

• CT scans frequently revealed an irregular cavity adjacent to the gallbladder neck.
• Calculi (gallstones) were often observed outside the gallbladder lumen.
• While not entirely specific, these CT findings can indicate Mirizzi syndrome.

Implications:

• Computed tomography can aid in the pre-operative diagnosis of Mirizzi syndrome.
• Accurate pre-surgical identification improves surgical planning and patient outcomes.
• Further research can refine CT criteria for earlier and more definitive diagnosis.
