The major medical problem was defined as the presence of at least two chronic systemic diseases, such as hospitalization and/or treatment-requiring diabetes mellitus, congestive heart failure, peripheral arterial disease, renal failure, or transplantation. It was found to be significantly high in the patient population in which RPP was detected
This patient, who presented with intracerebral hemorrhage, was diagnosed as amyloid angiopathy proven by pathologically
