Background and Objective: Inflammatory pseudotumor is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. Some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. The aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflamm...

Mediastinal inflammatory pseudotumor is a rare benign disease with its capability for local invasion and rapid growth. We present a case of middle-mediastinal inflammatory pseudotumor and report its contrast-enhanced chest computed tomography, (18)F-fluorodeoxyglucose positron emission tomography/computed tomography and pathologic findings.

Inflammatory pseudotumor has been commonly reported in patients undertaking total hip replacement (THR) for different reasons. The precise etiology of this biological reaction and whether the primary disease has an influence on pseudotumor formation remain unclear. There seems to be a consensus that metal ions and debris do play an important role during this process. Recently, however, compared...

has been described in both genders of all ages, and in almost any location (1, 2). It is characterized histologically by the presence of acute and chronic inflammatory cells with a variable fibrous response (2). Its pathogenesis is uncertain, but the lesion is generally regarded as reactive or postinfectious, and it originates from an inflammatory process (2). It has been reported to occur in m...

We report a rare case of inflammatory pseudotumor of the prostate revealed on suprapubic prostatectomy. A 70-year-old man presented with nocturia, urgency and difficulty in voiding. The histopathological examination of the suprapubic adenomectomy specimen reported fibromyxoid pseudosarcomatous tumor (inflammatory prostatic pseudotumor). It is important to take this benign lesion under considera...

hepatic inflammatory pseudotumor (ipt) is a rare non-neoplastic process of unknown etiology, generally following a benign inflammatory condition. it is often mistaken as an either primary or metastatic malignancy in imaging studies. we report a 48 year-old female with numerous target lesions (2-4 cm) seen on high resolution ultrasound, spiral ct scan, and mri in all liver lobes compatible with ...

Inflammatory pseudotumor refers to a nonmalignant or low-grade neoplastic lesion characterized by the presence of spindle-cell proliferation with abundant inflammatory cells. Lung and orbit are the most frequent sites of occurrence, but the lesions may originate in nearly every site in the body, including the abdomen. We present a rare and interesting case of inflammatory pseudotumor of the col...

The inflammatory pseudotumor of the liver is an exceptional hepatic lesion first described in 1953 by Pack et al. (1,2) that mimics a malignant tumor but has benign histology and good clinical outcome. Its exact etiology is still unknown (2-4) but has been associated with some systemic inflammatory disorders (1,3). We present a case of a multiple hepatic inflammatory pseudotumor with spontaneou...
