Cyberknife radiosurgery for cranial plasma cell tumor
2014
Cranial and intracranial involvement by myelomatous disease is relatively uncommon. Furthermore, systemic manifestations of multiple myeloma are present in the majority of these cases at the time of symptom onset. The authors report the case of a patient with serial appearance of multiple intracranial plasma cell tumor localizations as the first manifestations of a multiple myeloma. The patient was treated with CyberKnife radiosurgery for a lesion localized at the clivus and sella turcica with complete local control. With such a technique, based on high-dose conformality, the tumor was centered with an ablative dose of radiation and, at the same time, with a low dose spreading to the surrou…
Peritumoral Edema in Meningiomas
1994
Although generally benign tumors, meningiomas may be associated with extensive peritumoral brain edema as seen on computed tomographic scans. Fifty-two patients with intracranial meningiomas were studied, and the hypodense areas on computed tomographic scans were related to the intraoperative microsurgical findings and to the sizes of the tumors. We have identified three kinds of tumor-brain interfaces characterized by different difficulties in microsurgical dissection: smooth type, transitional type, and invasive type. These different microsurgical interfaces seem to correlate very precisely with computed tomographic images of halo-like and finger-like hypodense areas, allowing prediction …
