Meningiomas causing intracranial hemorrhage are rare, and hemorrhage from a lateral ventricular meningioma seems to be even rarer. We report a case of trigonal meningioma in a 43-year-old woman who presented with intraventricular hemorrhage, and describe the CT, MRI and angiographic findings.

A boy, aged 5 years, was admitted due to chest pain for 4 months, right lower limb weakness for 2 months, and weakness of both lower limbs for 10 days. There were no symptoms of defecation/urination disorders or disturbance of consciousness, and the boy had upper motor neuron paralysis in both lower limbs, without cranial nerve involvement or sensory disorder. Spine magnetic resonance imaging revealed tumor in the spinal canal between cervical vertebra 6 and thoracic vertebra 2, which put pressure on the spinal cord. He was transferred to the department of neurosurgery for surgical treatment and fully recovered after tumor resection, and no recurrence was observed after 6 years of follow-up. The pathological diagnosis was clear cell meningioma (WHO grade II). For children with chest pain and dyskinesia, spinal meningioma should be considered.

Meningioma rarely manifests as a subarachnoid hemorrhage (SAH), and invasion directly into a major intracranial artery is extremely rare. To the best of our knowledge, meningioma presenting with an SAH associated with major intracranial arterial invasion has never been reported. We present a case of sphenoid ridge meningotheliomatous meningioma manifesting as an SAH without pathologically atypical or malignant features, due to direct tumor invasion into the middle cerebral artery.
