Patients with RCC were identified, and secondary hypophysitis was subsequently identified based on pathological and MRI findings. Pathologically, the presence of lymphocytic infiltration into the normal anterior pituitary gland was used as a criterion for determining hypophysitis. On MRI, RCCs showing marked thickening of the cyst wall and pituitary stalk swelling \u2265 3.5 mm were considered as hypophysitis. A comparative study was performed at our institution using retrospectively collected data on RCCs with secondary hypophysitis and common RCCs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>The study included 11 patients with RCC with secondary hypophysitis (median age 36 years) and 95 patients with common RCC (median age 51 years). The proportions of patients with headache (90.9% vs 48.4%, p = 0.009), fever (63.6% vs 1.1%, p &lt; 0.001), panhypopituitarism (90.9% vs 24.2%, p &lt; 0.001), and diabetes insipidus (90.9% vs 21.1%, p &lt; 0.001) were significantly higher in the RCC with secondary hypophysitis group than the common RCC group. Although reaccumulation rates and the time to reaccumulation did not differ between the groups, the operative rate when reaccumulation occurred was significantly higher in patients with RCC with secondary hypophysitis than in those with common RCC (75% vs 13%, p = 0.015).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>RCC with secondary hypophysitis was associated with a high incidence of headache, fever, panhypopituitarism, and diabetes insipidus. The reaccumulation rate and time to reaccumulation in the RCC with secondary hypophysitis group did not differ from those in the common RCC group; however, the operative rate at reaccumulation was extremely high for those with RCC with secondary hypophysitis, indicating the need for tailored management strategies. Future studies with larger sample sizes and refined criteria are essential to better understanding RCCs with secondary hypophysitis and to optimize therapeutic interventions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/2025.1.jns24892","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T21:47:37Z","timestamp":1745617657000},"page":"423-430","source":"Crossref","is-referenced-by-count":3,"title":["Clinical features of Rathke\u2019s cleft cyst with secondary hypophysitis and outcomes of endoscopic transnasal surgery versus features of common Rathke\u2019s cleft cysts: a single-center retrospective cohort study"],"prefix":"10.3171","volume":"143","author":[{"given":"Takuro","family":"Ehara","sequence":"first","affiliation":[{"name":"Departments of Hypothalamic and Pituitary Surgery"},{"name":"Department of Neuro-Oncology\/Neurosurgery, International Medical Center, Saitama Medical University, Hidaka, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noriaki","family":"Fukuhara","sequence":"additional","affiliation":[{"name":"Departments of Hypothalamic and Pituitary Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinji","family":"Ito","sequence":"additional","affiliation":[{"name":"Pathology, Toranomon Hospital, Minato City, Tokyo;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuo","family":"Okada","sequence":"additional","affiliation":[{"name":"Departments of Hypothalamic and Pituitary Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Nishioka","sequence":"additional","affiliation":[{"name":"Departments of Hypothalamic and Pituitary Surgery"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"3","key":"b1","series-title":"Endocr J","first-page":"357","article-title":"Prevalence of lymphocytic infiltrate in 1400 pituitary adenomas","volume":"45","author":"Heshmati HM","year":"1998","unstructured":"Heshmati HM, Kujas M, Casanova S,  Prevalence of lymphocytic infiltrate in 1400 pituitary adenomas.
