ABSTRACT
Rathke's cleft cyst is a non-neoplastic sellar cyst, which is increasingly reported on radiological investigation performed for unrelated intra-cranial pathology. When symptomatic, it is associated with headache, visual symptoms, and pituitary dysfunction. We report a case of an 18 year-old male patient with Rathke's cleft cyst, who presented with failing vision, headache, and hypocortisolism. After defaulting on planned surgery, the patient continued to take a replacement dose of prednisolone for a year. He reported significant improvement in vision and remarkable reduction in cyst size on repeat imaging after a year. Surgery was later performed in view of persisting severe headache. The authors discuss the reduction in cyst size in relation to long-term usage of replacement steroid. They postulate that selected patients with Rathke's cleft cyst with radiological evidence of inflammatory fluid can be given a trial of glucocorticoids and assessed for cyst shrinkage and changes in imaging characteristics.
