Imaging Diagnosis of Primary Brain Iymphoma / 实用放射学杂志

Objective:To describe the imaging findings of primary brain lymphoma in immunologically normal patients.Methods:The clinical manifestations and imaging findings of 5 patients operated with pathological proved primary brain lymphoma were reviewed.Results:In 5 cases,4 patients were men and one was woman.The median age was 47(range 34 to 63 years).Pathological diagnosis was compatible with primary non-Hodgkins lymphoma of brain for all five patients.Primary brain lymphoma may be soiltary or mutiple and locate at supratentorial or infratentorial.Lesions presented as an isodense to hyperdense on CT scan,hypointense on T1-weighted images and isointense or hyperintense to gray matter on T2-weighted images.Most lesions showed dense homogenous enhancement on CT and MR.Tumors associated with different degrees of mass effect.One patient received whole-body 18 FDG PET examination that presented as an intracranial hypermetabolic lesion.Conclusion:Primary brain lymphoma is a rare tumor that imaging findings overlap with those of other intracranial mass lesions,we can only make a suggestive diagnosis of primary brain lymphoma and pathological confirmation is meeded.

The Interventional Treatment of Hepatic, Splennic, and Pharyngeal Hemangiomas / 介入放射学杂志

Purpose: Three kinds of embolizing agents, sodium mirrhuate, lipiodol and gelfoam were used together in treating hemangiomas of liver, pharynx, and spleen by embolizing the arteries. Materials and methods: 35 patients with hemangiomas, 30 cases in liver, 1 in spleen, and 4 in pharynx, were treated with embolizing hepatic artery, splenic artery, maxillary arterry, and face artery, respectively. Results: Tumors decreased 20%～90% in size, and none of then had continued to grow after the treatment for 3～36 months. At the same time, the suitable dose of embolizing agent according to the size of the tumor, the injection speed, the observation of the curative effect and the precaution of the embolization were also discussed, It showed that the effect of this method was better than using only one or two kinds of embolizing agents togethes resued in only slight complications. Conclusion: We think this method is safe and effective by combined with embolizing agents in treating hemaiomas of different organs and tissues.
