CSF-oma Identification With Nuclear Medicine Shunt-o-GramSchmieder, Stephanie, MD; Schraml, Frank, MDClinical Nuclear Medicine: May 2019 - Volume 44 - Issue 5 - p 399–400 doi: 10.1097/RLU.0000000000002485 Interesting Images Buy Abstract Author InformationAuthors Article MetricsMetrics A nuclear medicine shunt-o-gram is used to evaluate ventriculoperitoneal shunt patency and dispersion of radiotracer into the peritoneal cavity. A 73-year-old man presented with worsening memory, gait disturbance, and urinary incontinence. Shunt-o-gram revealed antegrade flow through the tubing and spillage into the peritoneal cavity without dispersion. CT confirmed a CSF-oma. Symptoms resolved after CSF-oma resection. Normal passage of radiotracer through the shunt without normal dispersion into the peritoneal cavity along with CT imaging correctly identified a CSF-oma. This is an unexpected complication of a shunt. Correct diagnosis on imaging likely saved this patient from unnecessary complete shunt revision.
