Inflammatory pseudotumor of the liver: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Inflammatory pseudotumor of the liver represents a fairly uncommon pathology. Although it is a benign tumor, the correct diagnosis can be missed.</p> <p>Case presentation</p> <p>We report the case of a 55-year-old Caucasian man, who presented with a one-month history of abdominal pain and weight loss. He was diagnosed with a primary liver tumor by computed tomography and magnetic resonance imaging. Alpha-fetoprotein levels ranged within normal limits. A right posterior sectorectomy was performed. Histopathology revealed an inflammatory pseudotumor of the liver. Our patient remains in good condition one year later.</p> <p>Conclusion</p> <p>Although inflammatory pseudotumor of the liver is usually a benign process, controversy regarding its management still exists. With this case report we review the existing literature and consider hepatectomy as a safe treatment approach.</p

Inflammatory pseudo-tumor of the liver: a rare pathological entity

Inflammatory pseudo-tumor (IPT) of the liver is a rare benign neoplasm and is often mistaken as a malignant entity. Few cases have been reported in the literature and the precise etiology of inflammatory pseudotumor remains unknown. Patients usually present with fever, abdominal pain and jaundice. The proliferation of spindled myofibroblast cells mixed with variable amounts of reactive inflammatory cells is characteristics of IPT. We reviewed the literature regarding possible etiology for IPT with a possible suggested etiology

Micro-tensile testing of reduced-activation ferritic steel F82H irradiated with Fe and He ions

Micro-tensile tests were conducted on reduced-activation ferritic steel F82H specimens after irradiation with Feand He ions. The displacement damage levels were 50 and 200 dpa, and helium concentrations were 0, 2000 and5000 appm. The specimens had dimensions of 8 × 1 × 1 μm for the gage section and they were tension tested atroom temperature in a vacuum. The yield strengths of the unirradiated specimens were close to the literaturevalue reported for a large, unirradiated specimen. The increases in yield strength and ultimate tensile strengthdue to Fe ion irradiation were clearly observed. The loss of work hardening was confirmed for the 200 dpaspecimens (0 or 2000 appmHe). Higher yield strength and ultimate tensile strength were confirmed for the50 dpa/5000 appmHe specimen compared to the no helium specimen (50 dpa/0 appmHe). However, no ap-parent helium effects were confirmed for the 200 dpa/2000 appmHe specimen by the micro-tensile test at roomtemperature
