Symptomatic recurrence of an histologically verified intra- and suprasellar Rathke's
cleft cyst (RCC) was observed 4 months following transsphenoidal microsurgery. The
space-occupying cyst was treated by endocavitary irradiation with colloidal rhenium-186
via a previously implanted catheter with an attached subcutaneous reservoir. The calculated
dose of 4.4 Gy was able to stop the production of cyst fluid. Follow-up after intracavitary
irradiation extends over 13 months. The cyst, with an initial size of 3 × 3 × 4 cm,
has been reduced to 1.1 × 1.06 × 1.2 cm. The production of cyst fluid has decreased
from 25 - 30 ml within 2 months before treatment to zero. The patient's visual and
mental status as well as her quality of life are normal.
