In this study, the authors analyzed the clinical features of and operative technique for TC.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n A total of 95 consecutive cases of suprasellar craniopharyngioma that had been resected via the endoscopic expanded endonasal approach were retrospectively reviewed. Patients were divided into 2 groups: 34 in the TC group and 61 in the nontransinfundibular craniopharyngioma (NC) group. Clinical and radiographic features, intraoperative findings, histopathological and genetic findings, and surgical outcomes were analyzed and compared between groups.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n \n Compared with NC, TC was mostly seen in adult patients (97.1%); it was rare in children (2.9%). Clinical presentations tended toward headache, hydrocephalus, and diabetes insipidus. The relatively smaller volume, midline location (consistent with the stalk position), unidentifiable stalk, no shift of the third ventricle, and greater likelihood to involve the third ventricle and cause hydrocephalus were the characteristic features of TC in the preoperative MRI study. According to the degree of vertical extension of the tumor, the 34 TCs could be classified into 3 subtypes: type 1, entity was limited to stalk (n = 2, 5.9%); type 2, tumor extended up to the third ventricle (type 2a) or down to the subdiaphragmatic cavity (type 2b) (n = 23, 67.6%); and type 3, tumor extended in both directions (n = 9, 26.5%). For TC resection, the chiasm\u2013pituitary corridor, lamina terminalis corridor, and pituitary corridor could be used separately or jointly. Most of the TCs originated from the infundibulum\u2013tuber cinereum, grew within and along the long axis of the infundibulum, and the pituitary stalk was not usually preserved in TCs (20.6%), whereas the rate of preservation was higher (80.3%) in NCs. Bilateral hypothalamic injury was found in nearly all TCs if radical resection was performed, whereas the relationship between NCs and hypothalamus was either compression (32.8%) or unilateral invasion (67.2%). Meanwhile, the postoperative endocrine and neuropsychological function outcomes in patients with TC were worse than in patients with NC. The genetic analysis with whole-exome sequencing studies showed no differential mutations of\n CTNNB1<\/jats:italic>\n (\u03b2-catenin) and\n BRAF<\/jats:italic>\n (V600E) between TC and NC subtypes, but there was a difference between adamantinomatous craniopharyngioma and papillary craniopharyngioma.\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n TC is a special subtype of suprasellar craniopharyngioma, which is remarkably different from NC. Identification of this type of tumor preoperatively is essential for the planning of appropriate surgical approach and degree of excision.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2019.3.jns181953","type":"journal-article","created":{"date-parts":[[2019,6,14]],"date-time":"2019-06-14T19:50:44Z","timestamp":1560541844000},"page":"119-128","source":"Crossref","is-referenced-by-count":16,"title":["Clinical features and operative technique of transinfundibular craniopharyngioma"],"prefix":"10.3171","volume":"133","author":[{"given":"Bin","family":"Tang","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ShenHao","family":"Xie","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"GuanLin","family":"Huang","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZhiGang","family":"Wang","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Le","family":"Yang","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XuanYong","family":"Yang","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shan","family":"Xu","sequence":"additional","affiliation":[{"name":"Pathology, The First Affiliated Hospital of Nanchang University, Nanchang, Jiangxi Province, People\u2019s Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ErMing","family":"Zeng","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Hong","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Nat Genet","doi-asserted-by":"publisher","first-page":"285","DOI":"10.1038\/ng.2526","article-title":"Genomic sequencing of meningiomas identifies oncogenic SMO and AKT1 mutations","volume":"45","author":"Brastianos PK","year":"2013","unstructured":"Brastianos PK, Horowitz PM, Santagata S, Jones RT, McKenna A, Getz G, : Genomic sequencing of meningiomas identifies oncogenic SMO and AKT1 mutations.
