Summary
Capsular retraction, a sign typically seen in malignant liver tumors, was unexpectedly observed in a case of benign hepatic inflammatory pseudotumour (IPT). This finding expands the known associations for capsular retraction in liver lesions.
Area of Science:
- Hepatology
- Radiology
- Pathology
Background:
- Capsular retraction is a known radiological sign associated with malignant liver lesions, including hepatic metastases and intrahepatic cholangiocarcinoma.
- It is rarely seen with benign hepatic lesions like atypical hemangiomas.
Observation:
- This report details a rare case of capsular retraction associated with hepatic inflammatory pseudotumour (IPT).
- The patient was a 48-year-old woman presenting with multifocal hepatic IPTs.
Findings:
- Capsular retraction has not been previously reported in hepatic inflammatory pseudotumour.
- This case demonstrates that capsular retraction can occur in benign hepatic IPT.
Implications:
- The findings broaden the differential diagnosis for capsular retraction in liver imaging.
- Recognizing capsular retraction in IPT is important for accurate diagnosis and prognosis of this benign liver condition.
