“…Bilateral symmetrical perirenal involvement is typically seen in pathologic conditions like perirenal lymphoma, perinephric collections, hematoma, urinoma, abscesses, bilateral perirenal lymphangiomatosis, bilateral nephroblastomatosis perirenal extramedullary hematopoiesis, bilateral retroperitoneal tumors, and fibrosis [1]. These conditions can be renal, subcapsular, or perirenal in origin and often indistinguishable with respect to the same.…”

Fibromatosis and/or desmoid tumors which constitute less than 1% of all neoplasms and 3.0% of all soft-tissue tumors are pathologically benign proliferations of the fibroblasts but are locally aggressive with infiltrative type of growth and tendency toward recurrence. Bilateral symmetrical perirenal involvement has been described in many conditions which can be renal, subcapsular, or perirenal in origin. However, bilateral perirenal fibromatosis as an isolated presentation was very uncommon. We report an exceptionally rare case of bilateral perirenal fibromatosis with renal infiltration.

Acute conditions affecting the perinephric space: imaging anatomy, pathways of disease spread, and differential diagnosis

et al. 2012

View full text Add to dashboard Cite

The perinephric space is an important, central compartment of the retroperitoneum which may host various acute conditions. Imaging evaluation of the perinephric space requires an understanding of its anatomy and the pathways of disease spread to and from other retroperitoneal compartments. Numerous acute conditions can affect the perinephric space and may occur in isolation, extend from nearby retroperitoneal structures, or be part of a systemic condition. Familiarity with the key imaging findings of acute conditions affecting the perinephric space is imperative to facilitate diagnosis and guide treatment. The purpose of this article is to review and illustrate the relevant anatomy, pathways of disease spread, and acute pathology encountered during cross-sectional imaging evaluation of the perinephric space.
