- W2355103635 abstract "ObjectivesTo investigate the imaging characteristics of intracystic nodules in Rathke's cleft cysts(RCC) and analyzethe important role of intracystic nodules in making preoperative diagnosis of RCC.MethodsThe imaging data of 22 patients with RCCconfirmed by surgery were retrospectively analyzed and the value of the intracystic nodules on preoperative cranial MRI to the diagnosisof RCC was analyzed.ResultsThe correct diagnosis of RCC was preoperatively made in 16 cases. The intracystic nodules were found in5 patients with RCC which were definitely diagnosed as RCC before the operation. The intracystic nodules presented high signal on T1 weighted image(T1WI) in 3 cases, iso-signal on T1WI in 1 case, and no definite signal on T1WI in 1 case, but they presented low signalon T2weighted image and had no enhancement after the administration of gadopentetate dimeglumine in these 5 cases. The rate ofpreoperative correct diagnosis was 64.7% in other 17 cases without intracystic nodules. RCC were only in intrasellar region in 14patients, had suprasellar extension besides intrasellar lesions in 6 and were above the pituitary gland in 2.ConclusionsThe preoperativediagnosis of RCC is difficult. The rate of intracystic nodule in RCC is relatively lower on MRI, but it has specific value to making definitediagnosis of RCC." @default.
