Spinal Cerebrospinal Fluid Leak Demonstrated by Radioisotopic Cisternography

Abstract

Many conditions are known to cause a cerebrospinal fluid (CSF) fistula; one of them is lumbar puncture for contrast myelography. Reported here is the case of a man who underwent contrast myelography at the L2-L3 level and who presented with postural headaches and lumbalgia with radiation to the legs three weeks after the procedure. Tc-99m albumin isotopic cisternography at the L5-S1 level was performed and clearly depicted a functional CSF leak through the dura at the L2-L3 level and CSF suffusion along several rachidian roots. Scinticisternography may thus be used to localize accurately a CSF leak.
