CT characteristics of primary retroperitoneal neoplasms in children
European Journal of Radiology, 2010 Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults.

Imaging of primary retroperitoneal neoplasms.
Annali italiani di chirurgia, 2022 Retroperitoneal soft tissue tumors are frequently incidental findings on imaging tests as Computed tomography (CT) or Magnetic Resonance Imaging (MRI). Retroperitoneal soft tissue tumors are rare and therefore not common in daily radiological practice. Clinician and radiologist'skills to set retroperitoneal soft tissue tumors at presentation is crucial

Retroperitoneal pneumography in the diagnosis of retroperitoneal lymphomatous neoplasms
The American Journal of Medicine, 1955Abstract Retroperitoneal pneumography is a valuable adjunct in the diagnosis and demonstration of retroperitoneal lymphomatous neoplasms. Modification of the usual technic by the use of a polyethylene catheter for administration of the gas is recommended. Fluoroscopy and body section roentgenography are believed to be important additions to the usual

Retroperitoneal fibrosis secondary to metastatic neoplasm
Urology, 1977Retroperitoneal fibrosis may occur secondary to metastatic neoplasm and may simulate the features of the idiopathic variety. A case of retroperitoneal fibrosis due to gastric carcinoma is presented and the historical, physical, cystoscopic, urographic, operative, and pathologic similarities to the idiopathic form discussed.

CT Characteristics of Primary Retroperitoneal Neoplasms
Critical Reviews in Computed Tomography, 2004Primary retroperitoneal neoplasms account for only 0.1-0.2% of all malignancies. Retroperitoneal neoplasms are most commonly mesodermal, neurogenic or lymphatic in origin, with lymphoma, liposarcoma, leiomyosarcoma and malignant fibrous histiocytoma the vast majority of malignant primary retroperitoneal tumors.

RETROPERITONEAL TUMORS SIMULATING GENITAL TRACT NEOPLASMS
Obstetrical & Gynecological Survey, 1946Summary The subject of retroperitoneal and mesenteric tumors has been discussed. Both have common derivation in the extracoelomic mesenchyme. Lacking a satisfactory grouping encompassing all these tumors, a suggested classification is proposed. Tivelve cases front our records (an incidence of 1:1,093) are tabulated.

Adrenal Myelolipoma Simulating a Retroperitoneal Malignant Neoplasm
Journal of Urology, 1981We describe a case of a large myelolipoma (15 by 12 cm. maximum diameter) that was removed surgically and resembled clinically and semeiologically a malignant retroperitoneal tumor. The patient also had chronic pancreatitis and cholelithiasis. Experimental findings, as well as the frequent association of myelolipomas (usually small) with several ...
