Retroperitoneal Fibrosis Associated With Immunoglobulin IgG4-related Disease in the Differential Diagnosis in Retroperitoneal Tumours. Case Report

Publication date: September–October 2019Source: Reumatología Clínica (English Edition), Volume 15, Issue 5Author(s): Gabriela Ruiz Mar, Óscar E. Cárdenas Serrano, Jorge Roldan García, Abraham Cañavera-Constantino, Víctor M. Menéndez Trejo, Óscar Chapa AzuelaAbstractThe patient was a 55-year-old woman with a 4-month history of pain in left flank that irradiated to the lumbar region. Computed tomography revealed a cystic tumor in the retroperitoneal region that compresses the ureter and left renal pelvis in contact with pancreatic body and tail. Surgery was performed and the definitive pathological report diagnosed nodular retroperitoneal fibrosis associated with IgG4; Ki67-positive in germinal centers (5%) and IgG4-positive (40 plasma cells in 3 fields of 40×) by immunohistochemistry. Retroperitoneal fibrosis is a rare disease, that develops gradually and has an excellent response to steroid management. Surgical treatment is reserved for cases that compromise adjacent structures. Thus, identifying it when studying a retroperitoneal tumor leads to better prognosis and survival.ResumenPaciente de 55 años de edad con cuadro de dolor en flanco izquierdo irradiado a región lumbar de 4 meses de evolución, con tomografía axial computarizada que reporta tumoración quística en región retroperitoneal que comprime uréter y sistema pielocaliceal izquierdo en c...

Authors: Chu Y, Ge W, Wang X Abstract MicroRNAs (miRNAs) play crucial roles in the pathogenesis of neuropathic pain. The present study investigated the effects of miR-448 on the progression of neuropathic pain in a rat model of chronic constriction injury (CCI) of the sciatic nerve. Reverse-transcription quantitative polymerase chain reaction was conducted to detect the gene expression. The paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were used to assess the pain threshold. The protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α (TNF-α) were detecte...

Authors: Guo L, Chen B, Zhang L, Deng Y, Li H, Shi QD Abstract A 49-year-old female patient developed chest tightness and shortness of breath without apparent cause and presented to a local hospital. Chest radiography indicated increased thickening of the lung texture, increased multiple patchy densities in the lower lobes of the bilateral lungs and a slightly enlarged thyroid. The patient was treated for pulmonary infection with antibiotics but the symptoms persisted. A repeated CT scan revealed ground-glass attenuation of the bilateral lungs with multiple flaky exudates and visible bronchogenic signs. The symptom...

All people are the same; only their habits differ. ~ Confucius This is a post about what keeps us stuck and sets us free, about the good news behind bad luck, and the wrong way to want the right thing: It’s about our habits. Human beings are creatures of habit — even emotionally. But why is this? Why do we fall into routines? And why is it so hard to break a habit? The short answer is something called set point. You’re probably familiar with this idea if you have ever been on a diet or had a new year’s resolution. They both start well. You are going to make a change in your life and you are ready fo...

Authors: Xu J, Wang X, Xiao H, Xu J Abstract BACKGROUND To determine the difference in size-specific dose estimates (SSDEs), separately based on effective diameter (deff) and water equivalent diameter (dw) of the central slice of the scan range in computed tomography coronary angiography (CTCA). MATERIAL AND METHODS There were 134 patients who underwent CTCA examination, were electronically retrieved. SSDEs (SSDEdeff and SSDEdw) were calculated using 2 approaches: deff and dw. The median SSDEs and mean absolute relative difference of SSDEs were calculated. Linear regression model was used to assess the absolute rel...

We present the case of a 64-year-old woman complaining of left lower abdomen pain, repeated lower and upper tract urinary infections, emergency urinary incontinence and hematuria. The surgical history shows that she underwent a hysterectomy, caesarean section and appendectomy. The clinical examination emphasizes a normal abdomen, with a normal aspect of the post-operative scars and a second-degree cystocele. An abdominal computed tomography (CT) scan with contrast and a cystography were performed and showed a 16 mm lesion-like tumor on the left bladder wall respectively a third-degree vesicoureteral reflux. These investiga...
