case_images: Nuclear scintigraphy of cat 1 following IV injection of 99mTc diethylenetriamine penta-acetic acid (Tc-DTPA). (A) At 5 min following injection, the radiopharmaceutical is distributed through the body with increased signal in the kidneys (*) and urinary bladder ( ). (B) At 30 min following injection, the distribution is homogenous without the signal void in the region of the lungs. (C) At 3 h following injection, there is more radiopharmaceutical accumulated in a triangular shape within the thoracic cavity ( ) compared to other tissues.

case_images: In this case, 2.25 millicuries Tc-DTPA were administered intravenously and 60 s static images were acquired using a low-energy, all-purpose collimator at 5 min, 20 min, and hourly until 4 h following injection (Figures 1, 2).
case_images: Nuclear scintigraphy images (cat 1) 4 h following IV injection of Tc-DTPA, demonstrating accumulation of mobile radiopharmaceutical within the pleural space. (A) The patient is in right lateral recumbency. There is increased radiopharmaceutical in the thoracic cavity (*), which faintly outlines the cardiac silhouette. (B) The patient is placed in sternal recumbency with the gamma camera horizontal to the patient. The radiopharmaceutical in the thorax moves with gravity to a dependent (ventral) position ( ). (C) The patient is placed in dorsal recumbency on the gamma camera. The radiopharmaceutical in the thorax becomes more homogenously distributed and is evident in both hemithoraces ( ).

case_images: In this case, 2.25 millicuries Tc-DTPA were administered intravenously and 60 s static images were acquired using a low-energy, all-purpose collimator at 5 min, 20 min, and hourly until 4 h following injection (Figures 1, 2).
case_images: Sequential post-contrast CT images of cat 1 (A-C) and cat 2 (D-F) are provided during the venous phase (A,D), 4 min (B), 7 min (E), and 10 min (C,F) following contrast administration. (A) In the venous phase images, there is a faint blush of contrast media (*) extending from the cranial pole of the right kidney into the adjacent retroperitoneal effusion. (B) A rim of contrast media ( ) can be seen accumulating in the subcapsular space. (C) Contrast ( ) can be seen leaking from the patient's left kidney and accumulating in the retroperitoneal effusion. (D) Leakage of contrast (*) from the cranial pole of the right kidney into the retroperitoneal space is identified. (E) Degenerative renal changes are evident with numerous cortical cysts, and there is a thin rim of subcapsular contrast accumulation ( ). (F) By the later phases, the retroperitoneal space is filled with contrast ( ).

case_images: Thoracic and abdominal CT scan was performed (Figures 3D-F).
case_images: Intraoperative images of cat 1. (A) The edge of a renal capsular defect (black arrowheads) in the left kidney can be seen with adherence of retroperitoneal fat to the exposed renal parenchyma (white arrow). (B) After removal of adhesions, the renal parenchyma may be seen through the capsular defect.

case_images: Retroperitoneal fat was adhered to the exposed renal parenchyma (Figure 4) and local retroperitoneal fibrosis was detected in these regions.
