Pituitary adenoma and concomitant Rathke's cleft cyst: A case report and review of the literature

摘要

A 42-year-old woman was referred for evaluation of severe headache of two weeks' duration. Neurological examination was essentially normal. A visual field evaluation by neuro-ophthalmology revealed no visual field defect. The serum prolactin level was 39.36 ng/mL and other hormone levels were in a normal range. Magnetic resonance imaging (MRI) revealed an intrasellar cystic solid mass with suprasellar extension, which measured approximately 2.4 cm in the greatest dimension [Figure la]. The mass lesion showed two different intensities, iso-intense on Tl-weighted and hyper-intense on T2-weighted sequences with a hypo-intensity on Tl and T2-weighted image in the mass [Figure la and b]. Post-contrast image showed marked enhancement of the solid part [Figure lc]. Surgery was performed using the endonasal transsphenoidal approach. During surgery, a gray bulging mass with a capsule was exposed. Incision of the capsule revealed a grayish soft mass which was totally curetted. Clear yellowish mucoid fluid was aspirated during curettage.
