[CT findings of growth hormone secreting pituitary adenomas].
    No to shinkei = Brain and nerve, 1986, Volume: 38, Issue:3

    The value of high-resolution computed tomography (CT) in the diagnosis of pituitary adenoma has recently been stressed, especially of the coronal view with contrast enhancement. Analysis of the CT scans of 33 growth hormone (GH) secreting pituitary adenomas was done (11 cases of microadenomas, 7 cases of intrasellar adenomas 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 adenomas 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 adenoma was smooth in nine cases and irregular in six. Among seven cases of intrasellar adenoma one accompanied primary empty sella. 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 GH level increased with the increment of the size of adenoma. Serum GH levels in adenomas with ring enhancement were lower than those in the homogeneously enhanced adenomas of similar size. One case with marked enhancement showed the highest GH level among all adenomas of the presented series.(ABSTRACT TRUNCATED AT 250 WORDS)

Angiographic ablation of parathyroid adenomas.
    Radiology, 1979, Volume: 130, Issue:3

    Six mediastinal parathyroid adenomas were stained by infusing contrast agent through a catheter wedged in the feeding artery. Adenomas in the first three cases were stained unintentionally with small volumes of dilute contrast media and hypercalcemia recurred within 3 to 6 months. In the next three patients, adenomas were deliberately stained with larger doses of concentrated contrast media and these patients have remained normocalcemic from 2 to 18 months following staining. The permanency of parathyroid ablation following deliberate staining with contrast media has not been established.
