The authors report their 27-year experience regarding 35 cases of supratentorial brain metastasis from sarcoma treated in a single institution: these included ten osteosarcomas, seven leiomyosarcomas, five Ewing sarcomas, four malignant fibrous histiocytomas, three alveolar soft-part sarcomas (ASPS), two rhabdomyosarcomas, one liposarcoma, and three unclassified sarcomas. The first 15 cases of the series have already been described in a previous publication. Median survival after craniotomy was 9.8 months (range: 4-24). In patients with preoperative Karnofsky performance score (KPS) > 60 it was 12.8 months (range: 6.5-24 months) versus 5.4 months for those patients with a KPS ≤ 60 (P = 0.01). Eight patients had more than one lesion, six of which were treated in the last ten years. Of the three patients with ASPS, the first two were alive at 15 and 20 months (before being lost to follow-up) whereas the third patient is alive at 24 month follow-up. The authors conclude that surgery is more effective in treating selected patients with sarcoma metastatic to the brain, and that patients with metastasis from ASPS have good prognosis when submitted to surgical treatment. The complete removal of all brain metastases "en bloc" and a KPS > 60 are associated with the best prognosis. Finally, it seems that surgical indications for multiple brain metastases from sarcoma have increased during the last ten years. © 2009 Springer Science+Business Media, LLC.

Single brain metastases from cervical carcinomas are rare. We report two cases of solitary brain metastases, showing different histological types, which have been excised with microsurgical technique. Neuroendocrine differentiation does not seem to be connected to clinical behavior, indeed a poor prognosis depends on poorly differentiated histological types. In our cases, brain metastases were a late event and they have been successfully excised in microsurgery, thanks to their solitary and resectable nature, and a well-controlled primary disease. © 2011 Springer-Verlag.

The only environmental factor undoubtedly linked to an increased risk of brain tumors (including gliomas) is therapeutic X-rays. We aim to conduct a detailed study of radiation-induced low-grade gliomas, in order to better understand the pathogenesis of such gliomas. Furthermore, we want do prove whether or not there are significant differences, according to clinical features and biological behavior, between this type of tumor and general low-grade gliomas. We analyzed the existent literature of low-grade radiation-induced glioma case reports and other epidemiological reports based on the experience of the senior author. We were able to collect 20 cases of such gliomas. Demographic data and previous X-ray details, along with latency intervals of all patients are provided. The amount of radiation able to cause mutations is not necessarily very high, as tumors occur even after low doses of radiation (as 3–5 GY). The incidence of this kind of tumors may be underestimated and may rise in the future. Care must be taken when observing patients who were irradiated more than 10 years before, especially in the recent years in which access to radiosurgical and radiation therapies has increased in the general population for treating many cerebral pathologies. Radiation-induced low-grade gliomas appear to be different from general gliomas only in terms of age in which they occur. In terms of clinical and biological behavior, there seem to be no differences, even though exceptional cases are reported. © 2015, Springer-Verlag Italia.

Papillary tumor of the pineal region (PTPR) is a rare variety of CNS neoplasms and, since its first definition in 2003, only 64 cases have been described. PTPR is a primary neoplasm morphologically characterized by papillary structure staining for cytokeratin, transthyretin, neurone- specific enolase and S-100 protein. We report on a case of about 4 years' clinical history and neuroradiological follow-up of PTPR, in a 47-year-old Indian patient, with the aim of increasing the knowledge of its natural history. We describe through CT and MRI scans the natural evolution of this neoplasm, enhancing changes and morphologic structures involved, together with the final surgical treatment and pathological details. A mean growth rate average was calculated for this kind of lesion. In conclusion, the inexorable progressive growing nature of this tumor leads us to advocate an aggressive attitude among neurosurgeons and radiotherapists, with a precocious surgical approach when the suspicion rises. © 2011 Springer-Verlag.
