Incidental 99mTc-DTPA Uptake in Tarlov Cysts on Radionuclide SPECT/CT Cisternography.
Sacral perineural cysts are also known as Tarlov cysts. A 58-year-old man with suspected intracranial hypotension was evaluated with Tc-DTPA radionuclide cisternography. Radionuclide planar and SPECT/CT cisternography revealed Tc-DTPA uptake in sacral lesions. Spine MRI confirmed Tarlov cysts at the S1 and S2 levels.
