Among the 3270 treated patients, the diagnosis of double pituitary adenoma was established in 22 patients. Clinical, laboratory, detailed histopathological and diagnostics imaging data were collected and analyzed.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There were 21 cases of synchronous and one case of asynchronous double pituitary adenoma. The main clinical finding was acromegaly (12\/22) followed by Cushing\u2019s disease (3\/22). The diagnosis of synchronous double pituitary adenoma was suspected in the preoperative MRI in 11 patients. In the remaining patients the diagnosis of contiguous double pituitary adenoma was confirmed in the histopathological examination. There was no predilection for gender and the mean observation time was 74.2\u00a0months. In one case of Cushing\u2019s disease the occurrence of double pituitary adenoma led to the initial failure of achieving hormonal remission. One patient presented with double pituitary adenomas as a manifestation of Carney complex.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Double pituitary adenoma is a rare entity that can pose a significant challenge especially in the setting of Cushing\u2019s disease. Careful inspection of preoperative MRI and diagnostic work-up before transsphenoidal surgery and thorough histopathological microscopic examinations with immunohistochemical staining for all pituitary hormones is essential for establishing the diagnosis of double pituitary adenoma.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s11102-019-00996-2","type":"journal-article","created":{"date-parts":[[2019,10,9]],"date-time":"2019-10-09T10:07:47Z","timestamp":1570615667000},"page":"620-632","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Double pituitary adenomas in a large surgical series"],"prefix":"10.1007","volume":"22","author":[{"given":"Grzegorz","family":"Zieli\u0144ski","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1510-6209","authenticated-orcid":false,"given":"Emir Ahmed","family":"Sajjad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Maksymowicz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"P\u0119kul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Koziarski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,10,9]]},"reference":[{"issue":"2","key":"996_CR1","doi-asserted-by":"publisher","first-page":"341","DOI":"10.1227\/01.NEU.0000223437.51435.6E","volume":"59","author":"BW Scheithauer","year":"2006","unstructured":"Scheithauer BW, Gaffey TA, Lloyd RV, Sebo TJ, Kovacs KT, Horvath E, Yapicier O, Young WF Jr, Meyer FB, Kuroki T, Riehle DL, Laws ER Jr (2006) Pathobiology of pituitary adenomas and carcinomas.
