[CT findings of XXXX secreting @entity977 ].

The value of high-resolution computed tomography (CT) in the diagnosis of @entity977 has recently been stressed, especially of the coronal view with contrast enhancement. Analysis of the CT scans of 33 @entity2124 ( @entity2124 ) secreting @entity977 was done (11 cases of microadenomas, 7 cases of intrasellar @entity652 and 15 cases of macroadenomas with suprasellar extension). In macroadenomas, the density was high in five cases, high with isodense portion in two cases, mixed in four cases, isodense in three cases, and isodense and low dense in one case. Six @entity652 showed homogeneous density and nine were heterogeneous. After contrast enhancement, two cases showed marked enhancement, ten cases mild and three cases ring enhancement. Margin of @entity652 was smooth in nine cases and irregular in six. Among seven cases of intrasellar @entity652 one accompanied primary @entity4776 . In microadenomas ten of eleven cases had hypodense mass inside the normally enhanced pituitary gland. The margin was ill-defined in seven cases and well-defined in three. Eight cases had pituitary height 7 mm or more. Upper surface of the pituitary gland was convex upward in five cases, flat in four and concave in two. Deviation of pituitary stalk was found in seven cases. Bony changes of sellar floor were recognized in three cases. There was a tendency that serum @entity2124 level increased with the increment of the size of @entity652 . Serum @entity2124 levels in @entity652 with ring enhancement were lower than those in the homogeneously enhanced @entity652 of similar size. One case with marked enhancement showed the highest @entity2124 level among all @entity652 of the presented series.(ABSTRACT TRUNCATED AT 250 WORDS)
