Abstract
Objective To analysis and summary of magnetic resonance imaging features and differential diagnosis of the intraventricular common tumors in order to improve the diagnostic accuracy. Methods Make a retrospective analysis of the clini-cal manifestations and magnetic resonance signal of 34 cases of intraventricular tumor patients had been confirmed by pathology ex-amination. Results A larger proportion of the children and adolescents in 34 cases of patients. The most of tumors located in the lateral ventricle and a few of the tumors in the septum pellucidum. Choroid Plexus Papilloma was found only in the lateral ventri-cle. Most of ependymoma in the fourth cerebral ventricle. Most of Germ Cell Tumor located in the sella turcica. Most of the cranio-pharyngeal duct tumor located in the third ventricle. Astrocytoma and Meningioma distribution did not feature. Most patients whose lesions was showed moderate/long T1 signals or moderate/long T2 signal in the MRI scanning, very few of patients are short T1 signal or short T2 signal. The signal of short T1 and short T2 appears only in craniopharyngioma and meningioma. Most of the le-sions were enhancement inhomogeneous. There were 4 cases without signal enhancement. All lesions were often calcified and cyst-ic degeneration, but the bleeding was relatively rare. All of the lesions had hydrocephalus mostly. Half of the lesions had cerebral edema. Conclusion There are characteristic clinical symptoms and directly or indirectly magnetic resonance signals in the intra-ventricular tumors.关键词
