=====Shuntogram=====
Radionuclide shuntogram is important in the evaluation of [[cerebrospinal fluid shunt complication]]s such as mechanical failure, malpositioning, pseudocyst, or overdrainage. Bermo et al present a case of [[congenital hydrocephalus]] and posterior fossa cyst with multiple shunt procedures and revisions with breakage of the proximal tube of the [[ventriculoperitoneal shunt]] but preserved CSF drainage through the patent fibrous tract. Careful correlation with SPECT/CT images helped confirm the breakage and exclude CSF leak outside of the tract, which was suspected on planar images
