lnflammatory pseudotumor (IPT) is a rare, non-neoplastic inflammatory process. It is most commonly occurs in the orbit, but extension into brain parenchyma is uncommon. In a confirmed case of IPT, most cases show good improvement with steroid theraphy. A 50-year-old man with progressive left-eye visual disturbance and mass lesion was admitted in a hospital. A left orbital mass biopsy revealed w...

Pseudotumors associated with total hip arthroplasty have been associated with metal-on-metal and metal-on-polyethylene total hip arthroplasties due to a granulomatous foreign-body reaction to methyl methacrylate, polyethylene, or metal ion release, but they have not been related to prosthetic joint infections. In this paper, we report an unusual case of Candida albicans total hip arthroplasty i...

Calcifying fibrous pseudotumor is an uncommon lesion and has recently been recognized as a distinctive fibrous lesion. Esophageal calcifying fibrous pseudotumor is extremely rare and, to the best of our knowledge, has never been reported before. A 54-year-old woman underwent upper gastrointestinal endoscopy and endoscopic ultrasound because of intermittent dysphagia. The results showed 1 isoech...

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 inflamma...

Background and Importance: Inflammatory pseudotumors are benign tumors-like lesions of unknown cause. The most familiar sites for inflammatory pseudotumors are the orbit and respiratory tract. An inflammatory pseudo tumor of costo-vertebral junction is rare. Case Presentation: We presented here a 50-year-old male with two month history of progressive left cervico-brachial pain. The MRI&nb...

We report a patient who had an inflammatory pseudotumor (IPT) that invaded to the maxillary sinus and orbital cavity, with the left pterygopalatine fossa as the principal site; this is a very rare case. The patient was an 83-year-old woman who suddenly became aware of impairment in the eyesight and visual field of the left eye. CT images showed a neoplastic lesion that invaded to the maxillary ...

Unusual MR and CT findings of an inflammatory pseudotumor in the parapharyngeal space of a 73-year-old woman are reported. The mass was hypointense on T1- and T2-weighted images and demonstrated ring enhancement after contrast medium injection. Punctated calcifications were scattered at the periphery. Inflammatory pseudotumors in the parapharyngeal space are rare, and only three cases have been...

We report the case of a 33-year-old white female patient. Her personal history was unremarkable. She presented with a three-month history of progressive dysphagia, which was accompanied by vomiting after eating, weight loss (8 kg), and asthenia. Physical examination was normal. Laboratory test results showed microcytic hypochromic anemia (hemoglobin, 10.2 g/dL; mean corpuscular volume, 69 fL; a...

A 35-year-old woman presented with a history of vague epigastric pain which lasted for one day. She had no other gastrointestinal symptoms and had an unremarkable past history and physical examination. An ultrasound scan abdomen showed a 3×3.5 cm mass in the left lobe of liver. A CT scan showed an abnormal hypodense lesion with mild enhancement in the arterial phase, with a central calcificatio...
