“…However, the computerized tomographic (CT) appearance of this phenomenon has received little attention. The previously described appearance is a bilateral nephrographic abnormality involving the area of the kidneys included in the radiation field, usually the medial aspects [3,4]. We demonstrate a delayed nephrogram with prolonged corticomedullary differentiation.…”

We present two cases showing bilateral segmental delayed nephrograms secondary to radiation injury which occurred during radiation therapy for retroperitoneal adenopathy. The abnormal areas in the affected kidneys were not devoid of a nephrogram, but rather showed a persistent corticomedullary separation indicative of slowed perfusion. Linear margins not conforming to the normal renal lobular configuration were a confirmatory feature. Radiation injury should be included in the differential of both the asymmetric prolonged nephrogram and the "segmental" nephrogram.

“…Andersen et al described two cases of radiation nephritis with a decreased nephrogram in the affected areas [3], and Moore presented a single case with a focal delayed dense nephrogram following an initially normal appearance [4]. A prolonged corticomedullary differentiation was not noted.…”

“…CT findings of radiation-induced changes in the kidneys have also been described. 3,[7][8][9] While the irradiated renal tissue shows low attenuation during the early nephrogram phase as noted in our case and those reported in the literature, 3 the delayed ceCT demonstrated persistent nephrogram in the irradiated regions with clearance of contrast from nonirradiated regions. 7,9 This persistent nephrogram resembles iFDG and the increased 99m Tc-MDP activity at 1 to 3 hours after injection.…”

It is often challenging to assess renal activity on FDG-PET/CT due to intense physiological activity in the collecting system, thus any unusual intrarenal activity should be evaluated carefully. While increased bone tracer uptake in the irradiated region of the kidneys has been reported in the literature, altered biodistribution of FDG in irradiated renal tissue is not well described. We report a case of FDG PET/CT showing increased FDG activity in small portions of the kidneys that were previously irradiated.

Computed tomography of acute radiation nephritis

A patient with Hodgkin's disease received a fractionated 3,740 rad dosage over 4 weeks to a portal that included both kidneys. Three months later a computed tomographic scan obtained 2 hours after intravenous contrast injection demonstrated sharply demarcated, dense, persistent nephrograms corresponding to the irradiated areas. These changes are ascribed to acute radiation nephritis, reflecting tubular stasis and ischemia.
