Compression of medulla oblongata by the dissecting aneurysm of the vertebral artery 7 years after its rupture: case report

A 56-year-old female, who suffered a subarachnoid hemorrhage (SAH) due to spontaneous dissection of the right vertebral artery 7 years previously, was admitted to our hospital with headache and vertigo. She hadn't had any attacks of SAH for 7 years. A magnetic resonance imaging (MRI) showed a h...

Summary:A 56-year-old female, who suffered a subarachnoid hemorrhage (SAH) due to spontaneous dissection of the right vertebral artery 7 years previously, was admitted to our hospital with headache and vertigo. She hadn't had any attacks of SAH for 7 years. A magnetic resonance imaging (MRI) showed a high signal intensity mass and a low signal intensity due to calcification on the right ventrolateral surface of the medulla on both T1 and T2 weighted images. Vertebral angiography showed complete occlusion of the cervical segment of the right vertebral artery (VA). Left vertebral angiography didn't reveal any retrograde filling of the intracranial segment of the right VA through VA union. Thus, the spontaneous entrapment by dissection of the vertebral artery was demonstrated 7 years after SAH with MRI and serial angiography.
