Benign metastasizing meningioma.
Meningiomas represent about one sixth of all primary neoplasms of the central nervous system. They rarely metastasize outside the intracranial compartment. There are no clear criteria to identify the subset of aggressive tumors which recur locally or metastasize. Histological tumor grade is the most important predictor of recurrence or metastases. We report an unusual case of recurrent metastas...
متن کاملA Case of Metastasizing Meningioma.
Primary intracranial neoplasms rarely give rise to distant extracranial metastases despite the fact that many of them possess the other attributes of malignant neoplasms. Paradoxically it appears that extra-cranial metastases are more liable to originate from the less rather than the more malignant primaryintra-cranial neoplasms (Russell and Rubinstein, 1963). Cushing and Eisenhardt (1938) repo...

Chest X-ray showed multiple bilateral shadows in the pulmonary parenchyma (Figure 1). Asked about any clinical symptom, she just referred a light dyspnea in high exercise situations.

متن کامل"Benign" metastasizing meningiomas.
Less than one in 1000 meningiomas metastasizes. Although the angioblastic and hemangiopericytic tumors are believed by some authors to metastasize with a greater frequency than the other histologic forms of meningioma, most investigators believe that neither the histologic pattern, local aggressiveness, size, nor location of the tumor can be used accurately to predict which tumors will metastas...
متن کاملMalignant meningioma metastasizing through the cerebrospinal pathways.
A 53-year old man presented with a malignant meningioma which was incompletely removed. The tumour subsequently metastasized through the cerebrospinal pathways causing clinical signs through invasion of the cranial nerve roots. Microscopically, the metastatic deposits displayed a papillary pattern and increased anaplastic cytological features.
