Abstract:

Meningeal metastases are rare entities in clinical practice, they are frequently observed in known
cancer patients, cause of the improvement of life expectancy and diagnostic means; they represent
about 8% of metastases of the Central Nervous System (CNS).
We report three original observations of patients without neoplastic history, initially transferred
from the Emergency Department (ED), who are operated for a solitary leptomeningeal process
whose appearance on CT scan and MRI was a meningioma. The histological study confirmed
the metastatic nature of the lesions and the extension assessment allowed detecting the unknown
primary tumor. The post therapeutic follow-up did not show any complications or tumor recurrence
in our cases.
Although rare, leptomeningeal metastasis can radiologically mimic the typical appearance of a
meningioma, which leads to consider this pathology as a differential diagnosis of meningioma. In the
light of these observations and through a review of literature, we will discuss the physiopathological,
clinical, paraclinical, therapeutic and evolutionary aspects of this pathology.
