MS-31INTRACRANIAL MENINGIOMAS COMPLICATED BY HYPERTENSION: FOUR CASE REPORTS

BACKGROUND: The etiology and mechanism of both meningioma and hypertension are still not fully understood, and their diagnosis and treatment still need to be improved. The phenomenon that some meningiomas can directly lead hypertension was never reported previously. Here we reported four consecutive cases with hypertension secondary to intracranial meningiomas. CASE PRESENTATION: Case 1 was a 62-year-old woman with a meningioma (size: about 2.0 cm × 1.6 cm × 1.5 cm) at left frontal lobe and with a medical history of hypertension for 10 years; Case 2 was a 50-year-old woman with a meningioma (size: about 1.5 cm × 1.2 cm × 1.1 cm) at right parietal lobe and with a medical history of hypertension for 4 years; Case 3 was a 42-year-old woman with a meningioma (size: about 2.7 cm × 2.6 cm × 2.3 cm) in trigonum of left lateral ventricle and with a medical history of hypertension for 3 months; Case 4 was a 56-year-old woman with a meningioma (size: about 2.0 cm × 1.8 cm × 1.5 cm) at bilateral falx of frontal lobe and with a medical history of hypertension for 8 years. All the four cases were treated in our hospital from April to June in 2013. After surgical resection of the tumors, blood pressure of all the patients returned to normal level in a short term, and it remained stable for 10 to 12 months of postoperative follow-up period. CONCLUSION: These four cases may present a new clinical syndrome and provide important clinical insights, and also should attract the attention of clinicians, i.e. in patients with hypertension, coexisting intracranial meningiomas should be suspected, and appropriate diagnosis and aggressive surgical treatment should be provided; for patients with hypertension secondary to meningiomas, their hypertension can be cured after surgical removal of the tumors.
