Abstract:
Objective To investigate the clinical features and therapeutic strategies of one patient with meningioangiomatosis ( MA ) complicated with intracranial aneurysm formation. Methods The clinical data of one patient with aneurysm-formed MA admitted to the Department of Neurosurgery,the First Affiliated Hospital of Sun Yat-sen University was analyzed retrospectively. The patient received emergency craniotomy and middle cerebral artery aneurysm clipping and evacuation of intracranial hematoma. The meningeal tissue around the aneurysm was taken for pathological examination. Results Microscopy revealed meningeal thickening in the patient with MA accompanied with intracranial aneurysm. Spindle cells around the meninges and perivascular tissue of cortical hyperplasia formed an annular and fence-like structure. The results of immunohistochemistry showed the hyperplastic vessels and perivascular fibroblast like spindle cells diffuse vimentin-positive;the hyperplastic vascular endothelial cells CD99,CD34 were positive;and the residual glial cells in the lesions showed glial fibrillary acidic protein positive. Conclusion MA complicated with intracranial aneurysm is rare. The vascular condition is poor. The shape of aneurysm is irregular,and the risk of bleeding is high. Excise the involved meningeal tissue and clip the aneurysm with microsurgical operation is the resonable treatment.
