MULTIPLANAR MRI AND CT IMAGING OF SELLAR AND PARASELLAR TUMOURS WITH CLINICAL AND PATHOLOGICAL CORRELATION
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 19
Abstract
AIMS AND OBJECTIVES To review the anatomy of sellar and parasellar regions. To review a systematic anatomic approach to differential diagnosis of a sellar or parasellar tumors. To correlate the diagnosis on magnetic resonance imaging with pathological DIAGNOSIS. MATERIALS AND METHODS A Prospective study of a total of 40 consecutive patients who were referred to the department of Radiodiagnosis, Osmania General Hospital from December 2010 and September 2012 were included in the study after informed consent. RESULTS Majority of patients were between 20 to 40 years. Male preponderance was seen (Males 26, females 14). Commonest tumor encountered in our study was pituitary adenoma (65%) among which macro adenomas constituted about 50% of the cases and 15% of cases were micro adenomas. Most of the functioning adenomas were seen in females - of which prolactinoma was the commonest. CONCLUSION MR imaging is preferred over CT for the diagnosis of pituitary adenomas because it provides multiplanar high contrast images, higher definition of small sellar lesions (Microadenomas) of the pituitary and further it improves anatomical definition of the pituitary, optic chiasma compression, cavernous sinus invasion before surgery. It is also preferred for postsurgical surveillance. CT has a complementary role in delineating bony destruction and the visualization of calcification and preoperative planning. Coronal images are the best for anatomical details of this region.
