This article reports one case and presents a review of the literature on this topic. A 55-year-old man presented with acute drowsiness, aphasia and right homonymous hemianopsia and hemiparesis. The first CT scan showed a left occipitoparietal hematoma and the second one, nodular, contrast-enhanced lesions. He had been previously operated on soft tissues MFH. Lung metastases developed subsequently. A craniotomy was performed with evacuation of the hematoma and total gross resection of the mass lesions. Microscopic examination disclosed a metastasis from a MFH. Neoangiogenesis, stimulated by angiogenic growth factors, seems to take part in this vascular, stroke-like event. Due to longer survivals of patients harboring systemic sarcomas, these tumors should be considered in the differential diagnosis of intracranial neoplasms, whether hemorrhagic or not. In particular, h...

The potential advantages comparatively to surgery and conventional radiotherapy made this technique a very important tool in the therapeutic armamentarium of neurooncology. This series presents the experience of treating more than 100 intracranial lesions with linear accelerator-based radiosurgery at Hospital de Santa Maria in Lisbon with special emphasis on the indications and results. It also provides a review of the concepts and procedures of this modality as well as a general overview of the main published results in series of patients with brain tumors treated with stereotactic radiosurgery.
