Objectives: Inflammatory pseudotumor (IPT) of the liver is a rare benign lesion
which is commonly misdiagnosed as malignant tumor or liver abscess. Surgery is generally
unnecessary because of its benign course. The purpose of this study is to
determine non-surgical treatment options for IPT.
Patients and Methods: Among 1262 patients who underwent liver resection for
tumors from September 1989 to June 2004, seven patients had pathologically confirmed
IPT of the liver. All the seven patients background characteristics, pathologic
findings of the tumor, as well as early and late results were reviewed and analyzed.
Results: The liver function tests were all within normal range with a normal serum
-fetoprotein (AFP) and carcinoembryonic antigen (CEA). Abdominal ultrasonography
showed all tumors as hypoechoic lesions with unclear margin. Enhanced computed
tomography (CT) scans showed a low-density area with marginal enhancement
in six patients. One patient had liver cirrhosis. No complications occurred in any
patient after surgery. All patients survived, with the longest survival time to date
being 14 years.
Conclusions: In patients with or without positive hepatitis seromarkers and normal
tumor markers, if abdominal ultrasonography shows hypoechoic lesions with unclear
margin and CT scan shows a low-density area with marginal enhancement, IPT of the
liver could be suspected. If percutaneous liver needle biopsy confirms the diagnosis of
IPT of the liver, surgery can be avoided. |
