ABSTRACT

Aims & Objectives: This study aimed to describe the prevalence of the various lesions and to characterize imaging features of the sellar and parasellar lesions and to correlate between clinical and radiological diagnosis. Methodology: This study was done for the characterization of sellar & parasellar lesions with the help of MRI scan, which were done at the MRI centre, MB Hospital, Udaipur, Rajasthan from January 1, 2017, to December 2017. Medical case papers were reviewed for the primary clinical indication that led to a referral for pituitary MRI and serum prolactin levels were noted to follow up regarding surgical or conservative management was done. After analyzing the data results were expressed as frequency of occurrence and percentages of various lesions which were compared with clinical findings. Results: The study population consisted of 80 patients, of which majority were females. MRI revealed abnormality in 68% cases and it was found that combined sellar and suprasellar involvement was there in most of the patients, followed by pure intrasellar and parasellar involvement. Conclusion: The sellar and parasellar regions can be affected by a wide variety of lesions with almost similar presentation. When symptoms of mass effect, visual field deficits and endocrine abnormalities are not sufficient to distinguish these lesions, the use of MRI can helpful in reaching the proper diagnosis.

Key-words: MRI, Sellar, Parasellar Lesions.
