OBJECTIVE: Transinfundibular craniopharyngioma (TC) is one of the 4 subtypes of suprasellar craniopharyngioma. In this study, the authors analyzed the clinical features of and operative technique for TC. METHODS: 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. RESULTS: 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%).
