Neuro_MR_Brain: 29 F, history of VP shunt and progressive neurologic decline.
MRI BRAIN WITH AND WITHOUT CONTRAST:
CLINICAL HISTORY: 29-year-old woman with history of VP shunt, recent methamphetamine use and history of alcohol abuse, presenting with 2 months of progressive symptoms including stiffness, loss of function, nonambulatory, poorly interactive, and incontinent. Per report, normal outside MRIs.
Exam degraded by susceptibility artifact from shunt catheter, likely a programmable shunt.
1. No evidence of acute infarct, hemorrhage, mass effect, or abnormal enhancement.
2. Right frontal approach ventricular catheter terminates in the region of the left genu of the internal capsule, with catheter sideholes likely within frontal horn of right lateral ventricle. Ventricles are decompressed. T2 signal abnormality in the posterior body of the corpus callosum, may be related to decompression of hydrocephalus after shunt placement. Comparison with prior outside imaging may be useful to determine the stability of these findings.
