Infection and Peri-renal abcess have always been a diagnostic problem for radiologists. They cause high morbidity and mortality in late diagnosis. Ultrasonography (US) and CT-scan enable the radiologist to search the retroperitoneal space clearly and make a smart diagnosis by US and then drained with US guide are introduced. Low cost, high speed of drainage and complete response to therapy are ...
Neurofibromatosis Type 2 (NF2) is a dominantly inherited tumour-prone disorder, characterized by the development of multiple schwannomas, meningiomas and ependymomas. Its prevalence is around 1:60 000. Vestibular schwannoma (VS) is the hallmark of NF2. Retroperitoneal schwannomas are expected to occur in only 3% of cases. We present the case of a large retroperitoneal schwannoma in a patient wi...
Neuroblastoma is the most common extracranial solid tumor in childhood. In different classification of neuroblastomas, a subset of undifferentiated or poorly differentiated tumors with bizarre histological features has been mentioned. A 3-year-old girl presented with abdominal pain. Her haematological and biochemical parameters were normal except her urinary vanelylmandelic acid level was elevat...
INTRODUCTION One of the most important requirements in treatment of acute necrotizing pancreatitis is minimized invasion. AIM We are presenting experience in treatment of acute necrotizing pancreatitis by an original minimally invasive retroperitoneal necrosectomy technique, comparing our results to other studies, evaluating feasibility and safety, discussing advantages and disadvantages of t...
Giant lipomatous lesions of the thigh swelling with extension into retroperitoneum are rare. Lesions can be malignant or benign and can have similar clinical presentation. Treatments options differ and their prognosis varies with histology. We present two cases of liposarcoma and lipoma with the same clinical presentations that underwent surgical resection.
BACKGROUND The peak prevalence of retroperitoneal liposarcoma (RPLS) is between the age of 40 to 70 years, usually seen in male 1.43:1. RPLS during pregnancy is extremely rare and a challenge for both the surgeon and the pregnant woman. CASE PRESENTATION A 27-year-old woman was discovered to have a giant retroperitoneal tumor incidentally during her routine obstetric examination at 16 weeks o...
The first report in the world literature of the condition which is now generally known as idiopathic retroperitoneal fibrosis was that of Albarran (1905), but the first report in the English language did not appear until that of Ormond (1948). Since then many further case reports have been published, but the aetiology of the condition remains obscure. The disease usually presents as a urologica...
Liposarcomas are the most common mesenchymal tumors of the retroperitoneal space. Retroperitoneal liposarcomas are usually grown slowly and frequently reach a very large size before clinical recognition. Precise diagnosis and distinct multiplanar evaluation is essential for complete resection of these tumors. Here in we reported two cases with giant retroperitoneal liposarcomas which were evalu...
A case report is presented of a large retroperitoneal hibernoma along with the clinical, radiographic, and pathologic findings. Despite the unusual size and location of this hibernoma, the case illustrates the salient features of these rare tumors of brown fat origin. Pitfalls in preoperative diagnosis are discussed. To date, there has been no convincing evidence of malignant potential of this ...
Erdheim-Chester Disease is a multi-systemic condition characterized by non-Langerhans histiocytic infiltration. Cardiovascular involvement with pseudotumoral infiltration of the right atrium is present in approximately one-third of patients and may be asymptomatic. Although retroperitoneal fibrosis is common, perinephric dystrophic calcification has not been previously described.
