This is a report of a spinal intradural @entity145 associated with an enlarged filum terminale. A 9-year-old female was admitted to our hospital complaining of @entity158 . Neurological examination revealed no abnormal findings. CT scan showed a round shaped @entity66 in the right dorsolateral side of the spinal canal between the level of L1 to S1/2. The @entity66 disclosed isodensity and was not enhanced. A small low density @entity66 was visualized in the dural sac at the same level. MRI showed the @entity66 with low signal intensity on the T1-weighted image, and high signal intensity on the T2. The small @entity66 in the dural sac was demonstrated with low signal intensity on the T1 and T2-weighted image. In addition to this finding, @entity1645 was disclosed. It was suspected that this @entity66 was extradural @entity145 associated with an enlarged filum terminale. Osteoplastic laminotomy between L3 to S1/2 was performed, and an @entity145 was found in the intradural space. It compressed the cauda equina and enlarged tough filum terminale. The cyst was removed subtotally, and the filum terminale was cut off. Postoperative course was uneventful and the @entity158 disappeared. It was thought that this @entity158 might be derived from the intradural @entity145 , or the enlarged filum terminale.(ABSTRACT TRUNCATED AT 250 WORDS)
