• Thigh Pain

  A 54-year-old man presented with right lower abdominal and upper thigh pain. Cross-sectional imaging of the abdomen revealed right hydronephrosis caused by a mass adjacent to the bladder. [em-consulte.com]

Computed tomography (CT), magnetic resonance imaging (MRI), and endoscopic retrograde cholangiopancreatography (ERCP) are usually included in the diagnostic workup. [hematologyandoncology.net]

Workups for infectious causes for RPF including histoplasmosis or tuberculosis were negative. She has no history of radiation to the pelvis. [elynsgroup.com]

Workup IgG4-related disease is diagnosed on the basis of clinical, biochemical and histopathological findings. It is essential to exclude differential diagnoses, some of which are shown in box 2. [tidsskriftet.no]

Understanding of its various clinical manifestations, response to treatment and prognosis has grown substantially in the past decade. It is now recognized to involve potentially any organ system either one at a time or several at once. [medicine.emory.edu]

The prognosis for patients with the disorder varies according to the type. It is relatively good for idiopathic retroperitoneal fibrosis, with a small long-term effect on quality and quantity of life. [news-medical.net]

Etiology Secondary retroperitoneal fibrosis Malignancies and exposure to methysergide are the most common causes of secondary RPF ! [amboss.com]

A 79-year-old man had a 3.5-year history of edema of the lower extremities of unknown etiology. [ncbi.nlm.nih.gov]

Etiology Aetiology is unknown in most patients, hence the name ``idiopathic retroperitoneal fibrosis''. Diagnostic methods RPF can be diagnosed by computed tomography, magnetic resonance imaging or biopsy. [orpha.net]

Summary Epidemiology Its incidence varies between 0.4 and 1/200 000. Clinical description Symptoms may vary depending upon the location and extent of fibrotic growth. The commonest manifestations are pain, weight loss, nausea and vomiting. [orpha.net]

Epidemiology Retroperitoneal fibrosis is an uncommon disease that affects 1 person per 200,000-500,000 population per year, depending on the specific location. [news-medical.net]

Abstract Purpose of review Remarkable insights have been gleaned recently with regard to the pathophysiology of IgG4-related disease (IgG4-RD). [ncbi.nlm.nih.gov]

Pathophysiology: the role of IgG4 IgG4 itself is unlikely to drive the pathogenesis of IgG4-RD  The properties of the IgG4 molecule suggest that it would suppress inflammation. [slideshare.net]

This further supports the similar underlying pathophysiology of the two conditions. Similar results were seen in our patient who responded in the first week after starting the steroid therapy. [japi.org]

They concluded, "As knowledge of the pathophysiology of this fibroinflammatory disease advances, treatment algorithms are also likely to evolve to include therapies that target the problematic fibrotic lesions as well as the highly cellular lymphoplasmacytic [medpagetoday.com]

Since the majority of cases cannot be linked to any specific cause, prevention may not be possible. [healthline.com]

Since immunesuppressants or B-cell targeted therapies may halt or reverse progression, early diagnosis and treatment is important to prevent terminal fibrosis. [ard.bmj.com]
