Magnetic resonance imaging of tumours of the sellar region. Evaluation of treatment with bromocriptine retard.

Magnetic resonance imaging (MRI) with a superconductive 0.5 T magnet has been used in 10 patients with pituitary adenomas to evaluate the effect of bromocriptine treatment. Seven patients had prolactinomas, one a growth hormone (GH) producing adenoma and two patients null cell adenomas with slight hyperprolactinaemia. A single dose of 50 mg bromocriptine was given intramuscularly in a slow release preparation, followed after 6 weeks by 5 mg/day orally. Significant reduction of serum prolactin was noticed in all patients. Visual field defects disappeared rapidly. In all prolactinoma patients and in the patient with the GH producing adenoma MRI showed a decrease in tumour size. In 5 of these 8 patients MR signal analysis, aided by the use of a subtraction technique, clearly visualized the development of large intratumour cysts. In one further patient with a null cell adenoma there was also a rapid development of an intratumour cyst and an increase in tumour size. This patient was treated with transsphenoidal needle aspiration. In all tumour cases an increase in intensity quotients based on T1 and T2 relaxation times was calculated.

Altitudinal field defects and retinal nerve fibre degeneration in optic nerve lesions.

Altitudinal visual field defects in five cases with optic nerve lesions due to optic glioma, compression, and trauma are correlated to retinal nerve fibre degeneration, recorded with ophthalmoscopy and photography in red-free light. In one case the optic nerve was damaged at operation. Repeated fundus photography was used to record the evolution of descending optic atrophy. The results suggest that the findings in funduscopic examination of the retinal nerve fibre layer should be cautiously judged and the method cannot replace careful perimetry in cooperative patients.

Haemangio-endothelioma of the orbit.

A case of infantile orbital haemangio-endothelioma was successfully treated with corticosteroids. Roentgenological and histological findings before and after treatment are described. It is suggested that an haemangio-endothelioma may be transformed into a cavernous angioma.

Double point test with the Goldmann perimeter.

A simple accessory to the Goldmann perimeter, permitting simultaneous projection of two targets, is described. The method can be used as a colour saturation test but also for the study of inattention hemianopia. Two cases illustrate its clinical application.
