Cyst infection in renal allograft recipients with adult polycystic kidney disease: the diagnostic value of labeled leukocyte scanning: case reports.

Occult infection following renal transplantation is a common diagnostic problem facing nephrologists and transplant surgeons. Patients with adult polycystic kidney disease (APKD) are prone to recurrent infections in their native kidneys and this can present with little if any localizing signs. Conventional radiological imaging with computed tomography or ultrasonography has a low sensitivity and specificity in such patients due to anatomic distortion and poor native renal function, and therefore identifying the source of sepsis can be difficult.
