Description

<p>At present, computed tomography (CT) myelography, magnetic resonance myelography, and radioisotope cisternography (RIC) are the main diagnostic imaging techniques for cerebrospinal fluid leakage. RIC is used in our hospital, although only a few cases can be diagnosed with RIC alone. We encountered three cases in whom a definitive diagnosis was possible using RIC combined with single photon emission CT (SPECT/CT). SPECT/CT is a three-dimensional imaging technique that measures the administered radiation distribution and superimposes it onto the CT image. SPECT/CT clearly showed the anatomical position of the leakage site, could accurately determine the leakage direction, and led to leakage site healing following treatment with an effective epidural blood patch. If CT myelography cannot be performed because of a contrast agent allergy, or if a clear diagnosis cannot be made on the basis of existing imaging criteria, combining RIC with SPECT/CT may provide a sensitive diagnostic option for cerebrospinal fluid leakage.</p>
