Spontaneous Intraventricular Hemorrhage Caused by Sphenoid Meningioma

The aim of the present study was to explore the clinical characteristics of repeated hemorrhages of meningioma and analyze the causes of hemorrhage. Meningiomas are mostly benign tumors that rarely manifest hemorrhagic strokes. In the present study, a case of sphenoid ridge meningioma with repeated hemorrhages is reported. Internal hemorrhage was first observed, which, on further aggravation, formed a hematoma in the brain parenchyma and finally led to the development of a hernia. No neurological deficit was present after surgery and rehabilitation. A postoperative pathological examination showed increased levels of Ki-67, abnormal blood vessels in the tumors and the presence of progesterone, which indicate possible causes of the hemorrhage. A review of associated previous studies revealed that hemorrhages originate mainly from inside the meningioma. Two cases of meningiomas with repeated hemorrhages have been reported; one in the foramen magnum region and the other in the pineal gland area. The foramen magnum tumor had an interval of 1.33 months between two hemorrhagic episodes. Collecting relevant data from the latter case was not possible. In the present case report, the interval between two bleeding episodes was 3 days. The literature review also revealed that the average age of onset of meningioma is relatively young at only 28.00±6.24 years. In conclusion, repeated hemorrhages in meningiomas are extremely rare and the causes have not yet been identified. Increased Ki-67 and abnormally proliferating blood vessels may be potential causes of hemorrhage. Early diagnosis and rapid surgical intervention are essential to prevent further episodes of bleeding, which may otherwise have fatal consequences for the patients.
