[Giant aneurysm of both vertebral arteries. Drop-attacks (author's transl)]

A 79 year-old woman suffered from drop-attacks for 2 years. There were in addition disorders of swallowing. She then had a mild right hemiplegia. At age 81, she had a mild spastic quadriparesis with paresis of the right sterno-mastoid and trapezius muscles and of the right side of the tongue. She died from bronchopneumonia. At autopsy a giant aneurysm involving both vertebral arteries was present. This case exemplifies: 1) drop-attacks due to a lesion near the foramen magnum; 2) signs which may suggest an aneurysm of the posterior fossa; 3) an apparently very rare kind of aneurysm of the vertebral arteries.
