18 @entity1 with "primary @entity4776 " were reviewed for this study. In 3 of them the sellar enlargement was discovered occasionally by performing skull radiographs for other reasons. The galattorrhea-dismenorrhea or @entity2588 and @entity28 were the most common clinical features. Endocrinological tests were normal in ten @entity1 and abnormal in eight. Slight elevation of serum PRL was the most common record. 12 @entity1 had @entity4776 ; in 4, only the floor was asymmetric and in 2 the sella was quite normal. In 5 @entity1 C.T. without intra-thecal contrast was sufficient to discover the E.S. In 13 @entity1 we performed C.T. cysternography by injecting in the lumbar subarachnoid space 8-10 ml of Iopamidolo 200. This is an excellent and safe technique to perform C.T. cysternography.
