Abstract:
✓ A brain tumor with histological features reminiscent of schwannoma with underlying meningioangiomatosis was subjected to electron microscopic and immunohistochemical analysis, which confirmed the neoplasm as a meningioma. This prompted reexamination of a similar tumor, described in a previous publication as a cerebral schwannoma, with identical immunohistochemical techniques. The results obtained favored alteration of this diagnosis to that of meningioma. This experience has led the authors to recommend the use of immunohistochemistry techniques when evaluating unusual intracranial neoplasms

Abstract:
Among the diagnoses to be mentioned before a brain tumor, that of tuberculosis, has retained a significant place in the developing countries. The extra axial form poses a real problem of differential diagnosis especially with meningioma. We report a case of a cerebral tuberculoma mimicking meningioma. A histological study is necessary in order to make a correct diagnosis and plan an adequate and early medical procedure.

Abstract:
Seizures occurring during pregnancy and postpartum may lead to the suspicion of eclampsia. However, it is essential to conduct paraclinical examinations (brain CT scan and brain MRI) to rule out cerebral expansive processes. In this main article, we report two cases of patients admitted for eclampsia, in whom a diagnosis of meningioma was made. Based on the observations, we discuss the different entities of this pathology with data from the literature.

We report a case of a left frontal lobe meningioma presenting in a woman with proteinuric preeclampsia in her first term pregnancy.

She had no residual disease and has had another successful pregnancy. This case highlights the importance of cerebral imaging in the context of an atypical clinical course of preeclampsia.
