Malignant 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.
متن کاملBenign 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...

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...
متن کاملPrimary mediastinal malignant meningioma.
Primary ectopic meningiomas are extremely rare tumors of controversial origin and they are usually limited to the head and neck region. Its occurrence at the mediastinum is even rarer. There has not been any official report regarding primary mediastinal malignant meningioma until today. Because of its rarity and potential value, we report here a case of primary mediastinal malignant meningioma,...
متن کاملMalignant Transformation of Pulmonary Benign Metastasizing Leiomyoma
Pulmonary benign metastasizing leiomyoma (PBML) is defined as metastasis of a leiomyoma to lung tissue. It was first reported in 1937. P BML is known as a benign disease, but can undergo malignant transformation. Only 1 case of the malignant transformation of PBML to leiomyosarcoma has been reported previously. In this report, we present a case of malignant transformation of PBML.
