1days in group II and Post-operative ultrasonography during hospitalization showed no
perinephric collection.
Allowable features within an oncocytoma include focal loss of cytoplasm in cells, imparting an oncoblastic appearance (B); focal degenerative-type atypia (C); and extension into the
perinephric adipose tissue (D) (hematoxylineosin, original magnifications X100 [A, B, and D] and X200 [C]).
Perinephric soft tissue infiltration was considered as the differential diagnosis of ECD.
MRI features of obstructive uropathy include an abrupt change in ureteral caliber, renal enlargement,
perinephric fluid, and when visible, a low-signal intensity ureteral filling defect on T2weighted imaging, which reflects the obstructing calculus (Figure 5).
The most common localization of primary dissection of
perinephric arteries is renal arteries (20).
Transient microscopic hematuria was seen in almost all patients; this was associated with post biopsy CT scan evidence of an intrarenal or
perinephric hematoma in 60 to 80 percent of patients.
No
perinephric effusion or hematoma was detected in the affected side during color Doppler ultrasound a day after surgery.
Endometriosis in a kidney with focal xanthogranulomatous pyelonephritis and a
perinephric abscess.
An abdominal and pelvic CT-scan was performed showing mild right
perinephric stranding with no hydronephrosis or hydroureter.
Moreover, it showed moderate
perinephric fat stranding with
perinephric fluid on the right side and thickening of anterior and posterior right pararenal fasciae.
apiospermum isolated from the perihepatic,
perinephric, and biloma fluid.
She subsequently developed hemodynamic instability from a retroperitoneal bleed secondary to hemorrhage of a massive left lower pole
perinephric mass containing few small vessels, as well as mixed fatty and soft tissue elements as seen on computerized tomography (Figure 1).
