Purpose:To describe the characteristic MRI findings of the Rathke cleft cyst. Materials and Methods:During a seven-year period, we retrospectively evaluated the MRI findings of 24 pathologically-proven Rathke cleft cysts. The patients icluded ten men and 14 women, And thier mean age was 37. MRI findings were analyzed in terms of location, shape, size, signal intensity, homogeneity of cyst content, pattern of contrast enhancement, displacement of the pituitary stalk, and mass effect of the cyst on adjacent structures. Results:The location of 14 cases (58%) was sellar or suprasellar. The mean size of the cyst was $16{ imes}$mm, as seen on sagittal or coronal images. The characteristic shape of the cyst was a sagging water bag in 13 cases (54%) and upward tenting in eleven(46%). The signal intensity of the cyst varied;on T1-and T2WI, eleven cases (46%) showed high signal intensity relative to brain parenchyma;five (21%) showed iso signal intensity on T1WI and high signal intensity on T2WI. While 18 (75%) showed inhomogeneous signal intensity on T1-and T2WI;13(54%) showed a smudge pattern within the cysts, and six (25%) showed homogeneous signal intensity on T1 and T2WI. On Gd-DTPA enhanced images, thin-rim enhancement surrounding the cyst was seen in 20 cases(83%). While no enhancement was seen within the cyst. Seventeen cases (71%) showed anterior displacement of the pituitary stalk;two showed posterior displacement bony erosion or tilting of the sellar floor(8 cases). Conclusion:MRI findings of midline intrasellar cyst with a sagging water bag appearance, high signal intensity on T1-and T2WI, inhomogeneity of cyst content, and peripheral rim enhancement surrounding the cyst are common, and are characteristic of the Rathke cleft cyst.

N/A 131I-6β-iodomethyl-19-norcholesterol(NP-59) has an advantage to assess adrenal dysfunction caused by adrenal cortical disorders. The aim of this study is to evaluate the clinical usefulness of NP-59 scintigraphy in each adrenral disease. Ten patients who did eleven NP-59 adrenal scintigraphies at Dong-A University Hospital from March 1990 to December 1996 were selected as the subject. Among the subject there were 5 cases of Cushing's syndrome, 2 cases of incidentaloma, 1 case of metastatic adrenal tumor, liver cirrhosis with hirsutism and hypertension respectively. Among 5 case of Cushing's syndrome, there were 2 cases of Cushing's disease, 2 cases of adrenal adenoma and 1 case of adrenal carcinoma. There are no disagreement between clinical diagnosis and scan finding in Cushing's syndrome. In 2 incidentaloma cases, even though one is interpretated as a functioning tumor, both of 2 cases could avoid unnecessary biopsy according to scintigraphy result. One case of hirsutism, clinically adrenal originated, revealed the normal scintigraphic hirsutism was extra-adrenal origin. One case of hypertension took the study to exclude the possibility of primary aldosteronism. Normal suppression scan finding revealed that primary aldosteronism did not exist in this case. In conclusion, NP-59 scintigraphy was very useful in diagnosis and differential diagnosis of Cushing's syndrome and it could avoid unnecessary biopsy in the incidental adrenal tumor.
