RESUMO
Seven patients with cystic meningioma are reported. The computerized tomography appearance of these meningiomas may mimic that of a glial or metastatic tumor with cystic or necrotic changes, and lead to an incorrect presumptive diagnosis. Radiological evaluation and recognition are important for the surgical removal of these potentially curable neoplasms.

The authors report a case of brachial vein epithelioid hemangioendothelioma resembling a median nerve neoplasm clinically and radiologically. It was found as a mass closely attached to median nerve and arising from one of two brachial veins. Simple resection, requiring sacrifice of the vein, allowed nerve median sparing but recurrence occurred one year later. Hemangioendothelioma should be also considered in differential diagnosis and in the planning surgery of arm median nerve masses. Wide local excision is surgical treatment recommended in those cases when regional lymph nodes or systemic metastasis have not been recognized. Regional lymph nodes resection and adjunctive radiation and chemo-therapy should be considered only for "malignant" or metastatic hemangioendothelioma.

A xanthomatous lesion of vermis cerebelli was removed successfully from the posterior fossa of a 19 years old girl with insulin-dependent diabetes and hypercholesterolemia, admitted for cerebellar hemorrhage. A review of literature shows that this is the first case of xanthomatous lesion presented with cerebellar hemorrhage. The pathogenesis of this lesion is reviewed as it relates to the presentation of this case.

The Authors report their results on the treatment of 10 cases of primary spinal epidural lymphoma. All patients underwent surgery followed by radiotherapy and 60% of them improved after treatment. The Authors stress the importance the preoperative neurological status and early diagnosis play on the prognosis. They conclude that only further studies on a large series can determine the influence of the histological type of the neoplasm on prognosis.

By examining 8244 clinical records, in a period of 12 years of paediatric activity, the authors point out the connection between dental caries and rheumatic fever. They suggest fluoride supplementation since the early age, in countries where the fluoride is lack in drink able-water.
