While the differentials of sellar masses are quite large and form an extensive list and the management protocol varies in each case, the onus of properly categorizing and diagnosing the pituitary mass often falls on the reporting radiologist. We hereby present two such unusual masses in the sellar-suprasellar region which were masquerading as pituitary macro adenomas. Materials and Methods: Two cases of sellar-suprasellar masses which were preoperatively diagnosed as pituitary macro-adenomas on radiological imaging proved out to be pituitary natural killer cell lymphoma and lepromatous abscess. Results: The first one is a rare case of pituitary abscess seen in a lepromatous patient which is not yet reported in the literature. The second case is of primary pituitary natural killer cell lymphoma which is almost entirely unknown, with only two such cases being reported worldwide till date. Conclusion: It is important to realize that all enhancing pituitary lesions are not macro adenomas and it is necessary to have a high index of suspicion in such cases. The clinical implications of such an error and steps that can be taken to prevent misinterpretations of unusual sellar masses camouflaging as pituitary macro adenomas have been briefly outlined.<\/jats:p>","DOI":"10.4103\/ajns.ajns_17_17","type":"journal-article","created":{"date-parts":[[2018,4,25]],"date-time":"2018-04-25T12:01:21Z","timestamp":1524657681000},"page":"1005-1007","source":"Crossref","is-referenced-by-count":8,"title":["Unravelling hitherto unreported masses camouflaged as pituitary macro adenomas"],"prefix":"10.1055","volume":"13","author":[{"given":"Vernon","family":"Velho","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, J.J.
