A 50-year-old woman presented with epigastralgia. Computed tomography (CT) of the abdomen revealed a 6-cm well-enhanced mass extending from the left lobe of the liver to the abdominal wall, suggestive of cholangiocarcinoma. Liver and skin mass biopsies did not provide evidence of hepatic malignancy but were rich in plasma cells and sclerotic lesions. Subsequent detection of elevated serum immunoglobulin G4 (IgG4) led to a diagnosis IgG4-related inflammatory pseudotumor (IPT) of the liver. Treatment with systemic corticosteroids resulted in rapid clinical improvement...

REVIEW
Claudia F E Kirsch, Karen Black
When patients see double with both eyes open, known as "binocular diplopia," this may be a harbinger of underlying life-threatening causes. This article presents pertinent anatomy, critical abnormality, and radiographic features that should be double checked for in diplopia. Key areas requiring a double check using the acronym VISION include Vascular, Infectious and Inflammatory, the Scalp for giant cell arteritis, Sphenoid and Skull base in trauma, Increased intracranial pressure (pseudotumor cerebri), Onset of new headaches or psychosis, and Neoplasm...

Orbital inflammatory pseudotumor is a rare complication of systemic lupus erythematosus. It may present a challenge for differential diagnosis, especially in the context of treatment with hydroxychloroquine, although dosage and duration of the treatment may guide us. Although high antibody titers can be found, this is not specific.

The actinomycosis is a suppurative infection due to an anaerobic and microaerophillic bacteria called actinomyces. Only few case reports are described for the mediastinal locations of this rare entity. We report a new case of inflammatory pseudotumor in the mediastinum due to Aggregatibacte actinomycetemcomitans revealed by hemoptysis. The mediastinoscopy procedure with biopsy was needed to confirm the definitive bacteriological diagnosis by a positive culture. During the postoperative course, a cutaneous fistula was found which had a favourable evolution after appropriate antibiotherapy...

Here, we present the first cytological report of a primary splenic inflammatory pseudotumor-like follicular dendritic cell sarcoma. The 57 year-old male was incidentally found with a 2.2 cm well-demarcated splenic nodule. A sonography guided fine needle aspiration of the lesion was performed. The cytologic smears revealed loosely cohesive fragments of oval to spindle cells in a background of prominent lymphoplasmacytic infiltration. The cells showed sparse chromatin, distinct nucleoli, syncytial cell borders, and occasional cytoplasmic processes...

OBJECTIVE: IgG4-related disease (IgG4-RD) is an idiopathic inflammatory condition that causes pseudotumor formation in single or multiple organs, including those of the head and neck. Temporal bone involvement is rare, with only 3 cases of unilateral temporal bone IgG4-RD described in the literature. We report the first known case of IgG4-RD of bilateral temporal bones and describe its clinical presentation, diagnosis, and treatment. METHODS: The patient was a 52-year-old man with latent tuberculosis (TB) who presented with a 10-year history of bilateral profound hearing loss and vestibular dysfunction...

INTRODUCTION: Meckel's diverticulum is a common malformation in children, usually asymptomatic, with complications in only 20% of cases. Exceptionally, a tumor can develop in Meckel's diverticulum in children, particularly Burkitt's lymphoma; in adults it can develop into a gastrointestinal stromal tumor, a leiomyosarcoma, or a neuroendocrine tumor such as a carcinoid tumor. The diagnosis of inflammatory pseudotumor following an insidious perforation is rare. OBSERVATION: We report the case of a 14-month-old boy who presented with fever, asthenia, food refusal, and digestive complaints such as vomiting and tender abdomen suggesting appendicitis...

Amebiasis is uncommon in developed countries. Several case reports in the literature emphasize that both the presenting symptoms and the radiological findings of colonic amebiasis closely resemble more common conditions, such as idiopathic inflammatory bowel disease and gastro-intestinal malignancy. We describe a unique case of colonic amebiasis (amebomas) coexisting with signet-ring cell carcinoma of the ileocecal valve, the cecum and the appendix. Endoscopically, the ulcerated tumor was indistinguishable from the ulcerations and pseudotumors (amebomas) detected in the ascending colon...

BACKGROUND: Beside hepatocellular carcinoma, metastasis, and cholangiocarcinoma, the imaging findings of other relatively uncommon hepatic lesions are less discussed in the literature. Imaging diagnosis of these lesions is a daily challenge. In this article, we review the imaging characteristics of these neoplasms. METHODS: From January 2003 to December 2014, 4746 patients underwent liver biopsy or hepatic surgical resection in our hospital. We reviewed the pathological database retrospectively...

Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass...

Tuberculosis can involve any part of the body. Urogenital tuberculosis is a fairly common extra-pulmonary manifestation of tuberculosis and renal tuberculosis is the most common form of urogenital tuberculosis. Renal tuberculosis seldom presents as a mass, usually due to hydronephrosis of the involved kidney. However in extremely rare cases it may present as an inflammatory pseudotumor which may mimic renal cell carcinoma. We present a case of a 65- year- old male who was provisionally diagnosed as renal cell carcinoma based on clinical and radiological findings and managed accordingly but was finally diagnosed as renal tuberculosis based on histopathological examination of surgical specimen...

BACKGROUND: Tumefactive multiple sclerosis (MS) is an unusual variant of demyelinating disease characterized by lesions with pseudotumoral appearance on radiological imaging mimicking other space-occupying lesions, such as neoplasms, infections, and infarction. Especially when the patient's medical history is incompatible with MS, the differential diagnosis between these lesions constitutes a diagnostic challenge often requiring histological investigation. An older age at onset makes distinguishing tumefactive demyelinating lesion (TDL) from tumors even more challenging...

We present the case of a middle-aged woman with antecedents of cholecystectomy and several episodes of resi-dual coledocolitiasis resolved endoscopically. She attended Emergency Services due to a new clinical picture of abdo-minal pain and alteration of hepatic enzymes. Image tests showed lesions that suggested hepatic abscesses without ruling out a malign origin. Given this doubt it was decided to carry out a thick needle biopsy obtaining a diagnosis of an inflammatory pseudotumour of the liver related to IgG4-related disease...

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a systemic necrotizing vasculitis, which affects small and medium sized blood vessels and is often associated with cytoplasmic anti-neutrophil cytoplasmic antibodies (ANCA). Inflammatory pseudotumor is a rare condition characterized by the appearance of a mass lesion that mimics a malignant tumor both clinically and on imaging studies, but that is thought to have an inflammatory/reactive pathogenesis. We report a patient with a GPA which was originally diagnosed as malignancy...

Calcifying fibrous pseudotumor (CFP) is a rare benign soft tissue lesion. We herein present an extremely rare case of CFP of the adrenal gland. A 32-year-old male patient presented to our hospital with a tumor-like lesion in the area of the left adrenal gland detected by ultrasound during a routine check-up several days prior. Contrast-enhanced magnetic resonance imaging examination revealed a solitary, well-circumscribed mass, in close proximity to the medial arterial branch of the left adrenal gland. Histological examination revealed that the tumor consisted of sheets of varying amount of inflammatory cell infiltration; interstitial fibrosis and psammomatous calcifications were also observed...

Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a morphologically distinctive lesion. Although the clinical course of SANT is benign, its reactive or neoplastic nature remains to be clarified. Furthermore, some investigators have suggested that SANT is related to IgG4 sclerosing lesion or inflammatory pseudotumor with stromal cells positive for Epstein-Barr virus (EBV). In this study, we assessed 22 cases of SANT derived from adult women. Clinical data and follow-up information were obtained by chart review...

Paraneoplastic pemphigus (PNP) is an autoimmune blistering disease associated with neoplasms. The disease is most commonly of lymphoproliferative origin and presents high mortality. We describe a patient with PNP and myasthenia gravis associated with inflammatory pseudotumor-like follicular dendritic cell sarcoma, as well as the response to rituximab.

A hepatic inflammatory pseudotumor, which can be misdiagnosed as a malignant tumor, is a relatively uncommon tumor with nonspecific imaging manifestations. As a new diagnostic technique, contrast-enhanced sonography has become increasingly important in the diagnosis of liver focal lesions. Here we present 3 cases of histologically confirmed hepatic inflammatory pseudotumors diagnosed with contrast-enhanced sonography. "Fast-in and centrifugal-out" may be a characteristic contrast-enhanced sonographic enhancement pattern in the diagnosis of hepatic inflammatory pseudotumors, which needs confirmation in further studies...

BACKGROUND: Hepatic inflammatory pseudotumor (IPT) is a rare disease which often mimics a malignant tumor and is therefore often misdiagnosed and surgically resected. Recently, a concept of IgG4-related diseases (IgG4-RD) has been proposed that is becoming widely recognized and includes IgG4-related hepatic IPT. Corticosteroids are widely accepted as the standard treatment. CASE PRESENTATION: A 72-year-old Japanese man, who had been followed for ten years after surgery and chemotherapy for treatment of hilar and lower bile duct cancers, developed intermittent fever and abdominal pain and visited this hospital...
