Can you tell me how wagner disease and a stroke occur simutaneously?

Rare manifestation: Neurologic manifestations of Wegener granulomatosis (WG) are primarily cranial neuropathies and peripheral neuropathies. Other neurologic manifestations include seizures, cerebritis, stroke syndromes, and granulomas extending from the sinuses, which may affect the pituitary gland, resulting in diabetes insipidus. Stroke is rarer.
