Radionuclide shuntography in a hydrocephalic patient

Radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in cerebro- spinal fluid flow. We present a case of complicated cerebro- spinal fluid shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. The findings were confirmed by surgery performed for correction of the shunt system
