Malign retroperitoneal schwannoma. The retroperitoneal tumors are infrequent and are classified according to the original tissue. This is a case presentation of a patient presenting with pain in right hypochondrium and a tumor in this zone, weight loss and painful discomfort in the anterolateral face of right thigh. In physical examination we found cutaneousmucous paleness and painless tumor in hypochondrium and right flank. Abdominal ultrasound US showed a homogenous mass of 14,11 cm and abdominal computed tomography allows to see a right retroperitoneal tumor rejecting the kidney.

Excretory urogram showed a anteromedial rejection of right kidney. An encapsulated tumor with a few peritumoral adherences was removed. By histological study it was possible to confirm a fusiform cells tumor with hyperchromatism and nuclear pleomorphism, numerous mitosis and areas of necrosis and in the diagnosis of malign tumor of the sheath of a peripheral nerve.

Lymphoplasmacytic Sclerosing Pancreatitis and Retroperitoneal Fibrosis. Directory of Open Access Journals Sweden. Full Text Available Although cases of lymphoplasmacytic sclerosing pancreatitis LSP associated with idiopathic retroperitoneal fibrosis have been reported, the association is rare. We describe a year-old man who presented with obstructive jaundice and weight loss.

Nineteen months earlier, he had been diagnosed with idiopathic retroperitoneal fibrosis and treated with bilateral ureteric stents. Initial investigations were suggestive of a diagnosis of LSP, however, a malignant cause could not be ruled out.

He underwent an exploratory laparotomy and frozen sections confirmed the diagnosis of LSP. An internal biliary bypass was performed using a Roux loop of jejunum, and the patient made an uneventful recovery. This case illustrates the difficulty in distinguishing LSP from pancreatic carcinoma preoperatively. Schwannoma retroperitoneal maligno Malign retroperitoneal schwannoma. In physical examination we found cutaneous-mucous paleness and painless tumor in hypochondrium and right flank.

Ormond's disease or secondary retroperitoneal fibrosis? An overview of retroperitoneal fibrosis. Heckmann, M. Radiologisches Inst. Retroperitoneal fibrosis represents a rare inflammatory disease. The remaining one third is secondary and may be ascribed to infections, trauma, radiation therapy, malignant diseases, and the use of certain drugs.

The clinical symptoms of retroperitoneal fibrosis are non-specific. In sonography retroperitoneal fibrosis appears as a retroperitoneal hypoechoic mass which can involve the ureters and thus cause hydronephrosis.

Intravenous urography and MR urography can demonstrate the typical triad of medial deviation and extrinsic compression of the ureters and hydronephrosis.

CT and MRI are the modalities of choice for the diagnosis and follow-up of this disease. The lesion typically begins at the level of the fourth or fifth lumbar vertebra and appears as a plaque, encasing the aorta and the inferior vena cava and often enveloping and medially displacing the ureters. In unenhanced CT, retroperitoneal fibrosis appears as a mass that is isodense with muscle. When using MRI, the mass is hypointense in T1-weighted images and of variable intensity in T2-weighted images according to its stage: it may be hyperintense in early stages, while the tissue may have a low signal in late stages.

After the administration of contrast media, enhancement is greatest in the early inflammatory phase and minimal in the late fibrotic phase. Dynamic gadolinium enhancement can be useful for assessing disease activity, monitoring response to treatment, and detecting relapse. To differentiate retroperitoneal masses, diffusion-weighted MRI may provide useful information.

Retroperitoneal fibrosis : findings with MR. We present a retrospective review of 3 cases of idiopathic RF studied by means of ultrasound, CT scan and MR imaging, and we assess the features of the MR image, as well as its capacity for characterizing the lesion.

We compare the findings obtained with 3 imaging techniques, describing the utility of each one, and their advantages and disadvantages in the assessment of this pathology. Author 9 ref.

Idiopathic retroperitoneal fibrosis IRF is an uncommon entity described as progressive proliferation of connective tissues leading to a fibrous plaque-like lesions that encases the aorta and inferior vena cava inferior to the level of the renal arteries. Mass forming retroperitoneal fibrosis is rare. We present a rare case of a Retroperitoneal fibrosis with pancreatic involvement — radiological appearance.

Obstructive hydronephrosis is often observed due to ureteral entrapment. This report presents a case of the peripancreatic location of the disease.

The role of CT and MRI in establishing diagnosis of retroperitoneal fibrosis in an atypical site is discussed. The patient was subjected to ultrasound, CT, and MRI which did not confirm urolithiasis but revealed pancreatic infiltration. Partial pancreatectomy, left-sided adrenalectomy and splenectomy were performed. Retroperitoneal fibrosis was diagnosed in the histopathological examination. A few weeks after surgery, a complication such as pancreatitis developed. Repeat CT confirmed it and showed right hydronephrosis secondary to ureteral involvement by a mass adjacent to the common iliac artery defined as a typical manifestation of retroperitoneal fibrosis.

Nephrostomy and conservative treatment improved the clinical state of the patient. No progression of the process was observed in the follow-up examinations. Atypical retroperitoneal fibrosis remains a diagnostic challenge. An unusual distribution of the process e.

A case of retroperitoneal fibrosis responding to steroid therapy. Enhanced computed tomography CT revealed a low density area in the retroperitoneal space.

A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis.

The size of the retroperitoneal soft tissue mass decreased gradually. Although the dose of prednisolone was tapered to 5mg, the patient is doing well without any sign of recurrence. Retroperitoneal fibrosis : the clinical and radiological manifestation. Objective: To analyze the clinical and radiological features of retroperitoneal fibrosis RPF , and to deepen the understanding of this unusual disease and improve the diagnostic level at the early stage.

Methods: Fourteen cases 10 males and 4 females, mean age The clinical and radiological performance of the cases were analyzed.

All patients received non-contrast CT scanning, 10 of them underwent enhanced CT scanning as well. Results: 1 The very first symptoms usually included back pain, bellyache 10 cases , or urinary tract obstruction 3 cases , with increase of ESR, IgG, CRP value and abnormal renal function. Ten cases were mass type and 4 cases were diffuse type. Non-contrast CT scanning revealed soft tissue mass at retroperitoneum with in homogenous or homogenous density. After contrast medium injection the lesions were enhanced with different extent.

MRI results showed that the lesions presented low signal in T 1 WI, while in T 2 WI the signals had no obvious coherence but were different from one case to another. Conclusion: Radiological examination is one of the important methods for diagnosis of RPF.

IgG4-related retroperitoneal fibrosis : a newly characterized disease. Retroperitoneal fibrosis RPF is a rare disease characterized by chronic, nonspecific inflammatory and sclerotic or fibrotic tissue in the periaortic or periiliac retroperitoneum that encases adjacent structures. There will be a series of clinical manifestations once the proliferated fibrous tissues encase the abdominal aorta, iliac arteries and urinary duct.

RPF is generally divided into two types: idiopathic retroperitoneal fibrosis IRPF without identified pathogenesis, making up about two-thirds of cases, and secondary retroperitoneal fibrosis. IgG4-related RPF is often misdiagnosed as retroperitoneal visceral malignancy and is treated with surgery. In addition, because of its good response to glucocorticoid, early detection and treatment is important.

We review the definition, epidemiology, clinical features, diagnostic criteria, treatment and prognosis of IgG4-related RPF in this article to raise awareness of this newly characterized disease. Spontaneous resolution of apparent radiation associated retroperitoneal fibrosis. A year-old man was diagnosed with retroperitoneal fibrosis RPF complicated by ureteral obstruction 4 months after finishing radiotherapy for prostate cancer.

He was treated conservatively with ureteral stent placement. After 3 months, computed tomography scan of the abdomen revealed resolution of RPF without any medical or surgical interventions. Although an uncommon event, the possibility of spontaneous resolution of RPF, as demonstrated by this and previously reported cases, has led some to encourage conservative management.

Pulmonary hyalinizing granuloma and retroperitoneal fibrosis in an adolescent. His PHG and RPF were not associated with histoplasmosis or tuberculosis and appeared to represent idiopathic autoimmune phenomena.

The use of F fluorodeoxyglucose positron emission tomography in the diagnostic and follow-up evaluation of PHG is reported. Young, Adam S. A rare case of Riedel's thyroiditis, 6 years after retroperitoneal fibrosis : two diseases with one pathogenesis? We describe a yr-old female patient in whom both a retroperitoneal fibrosis and 6 years later a Riedel's thyroiditis were diagnosed.

Both diseases belong to the group of fibrotic diseases called "multifocal fibrosis ". Retroperitoneal fibrosis is now known to be an auto-allergic reaction to lipid. Malignant nerve sheath tumours MPNST are rare neoplasias and retroperitoneal cases are fairly rare and clinically difficult to be detected, but they are very agressive neoplasias. MPNST are frequently seen in head, neck and upper extremities. It is necessary to be aware of a potential malignancy in patients diagnosed with plexiform neurofibroma.

The patient was admited to the hospital because of a tumour in the subcutaneous region on her left buttock. The surgeon's clinical diagnosis was lipoma. After the pathological examination of biopsy specimen, the lesion was identified as "plexiform neurofibroma" and then the patient was diagnosed with Neurofibromatosis Type 1 NF1.

Simultaneously, another mass on the retroperitoneal region was identified as malignant peripheral nerve sheath tumour MPNST.

Preferred Scientific Name; Jatropha gossypiifolia.. Jatropha gossypifolia is used in folkloric system to manage emesis and gastrointestinal motility disorders such as constipation and diarrhea. The present study. Plantas indeseables en los cultivos cubanos. Several human and veterinary uses in traditional medicine are described for different parts and preparations based on this plant. More commonly, the studies use solvents or mixtures of solvents with nonpolar characteristics, which could contribute to further characterization of nonpolar compounds, such as terpenoids and lignoids. Gossypifolia is suitable as a protein precipitant for creatinine, CSF and urinary protein estimations.
