Left panel: magnetic resonance (MR) imaging (T2 weighted image) of lumbar and sacral region. Enlarged spinal canal demonstrated in the sacral region. Upper right panel: radioisotope cisternographic findings of the lumbosacral region. Note that leakage of the radioisotope activity was found around the region caudal to the enlarged meningocele. Lower right panel: MR imaging (gadolinium enhanced, T1 weighted image) of the cranial region. No hygroma or subdural enhancement was found.
