Abstract：Objective: To analyze comprehensively the age, location, adjacent relationship and MR imaging features of space occupying lesions on the third ventricle region. Methods: Sixty-eight patients with space occupying lesions on the third ventricle region(confirmed by postoperative histopathology, following up) were reviewed in order to analyze their differences of the age, location, adjacent relationship and the MR imaging characteristics in this study. The correlationship between peritumoral appearance(periventricle extension, periventricle edema), MR imaging feature(T2WI, T1WI signal intensity, uniformity and enhancement pattern) and benign or malignant tumor was analyzed respectively. Results: Of 68 cases with third ventricle region tumor-like lesion(anterior part: 38 cases, upper part: 5 cases, posterior part: 16 cases, floor part: 3 cases, intraventricle: 6 cases), there included 14 non-neoplasm lesions and 54 tumor lesions(36 benign tumors and 18 malignant tumors). Germinoma, Langerhans cell histiocytosis(LCH) were seen commonly in children and adolescents; pituitary adenoma, papillary craniopharyngioma, hypothalamic-chiasmatic glioma and metastases were usually seen in middle-aged and old population; adamantinomatous craniopharyngioma were seen in 7 to 24 years old and 40 to 60 years old; the onset age of vascular lesions had no obvious specificity in our study. There was statistically significant difference between periventricle extension, periventricle edema and tumor malignancy, respectively(P<0.001). There was no statistically significant difference between T2WI, T1WI signal intensity, uniformity, enhancement pattern and tumor malignancy by single factor analysis(P>0.05). Conclusion: Comprehensive analysis of the age, location, adjacent relationship and imaging features of space occupying lesions on the third ventricle region may be helpful to improve their diagnoses and differential diagnoses, so as to guide clinical therapy.
