Regression of Intracranial Meningioma during Treatment with α(1)-Adrenoceptor Blocker

Background Regression of meningioma has been reported after hemorrhage or hormonal withdrawal. Here, we report a case of an incidentally diagnosed meningioma that regressed in association with α(1)-adrenoceptor antagonist. Case report A 59-year old male patient with an incidentally diagnosed lateral...

Sumario:Background Regression of meningioma has been reported after hemorrhage or hormonal withdrawal. Here, we report a case of an incidentally diagnosed meningioma that regressed in association with α(1)-adrenoceptor antagonist. Case report A 59-year old male patient with an incidentally diagnosed lateral sphenoid wing meningioma was followed with serial magnetic resonance imaging. The tumor with a maximum diameter of 43 mm showed progressive regression, and after 3 years the size was reduced to 22% of the initial volume. During follow-up the patient was treated with an α(1)-adrenoceptor antagonist (tamsulosin) for benign prostatic hyperplasia. Possible mechanisms are discussed, including our main hypothesis of reduced mitogenic effects through phospholipase C-signal transduction. Conclusion This is the first report of regression of an incidentally diagnosed meningioma associated with α(1)-adrenoceptor antagonist treatment.
