ABSTRACT
A patient with pheochromocytoma showed remarkable improvement of myocardial metaiodobenzylguanidine (MIBG) uptake within a short time after surgical resection of the tumor. Myocardial MIBG findings in this case may contribute to an interpretation of the kinetics of MIBG in the human heart.

The authors report a rare type of cardiac alternans during percutaneous transluminal coronary angioplasty (PTCA) in a patient with acute myocardial infarction. Not only ST segment but also QRS alternans were observed on electrocardiogram and were accompanied by mechanical alternans. The mechanism of these unusual findings is briefly discussed.

A formerly healthy 32-year-old woman was hospitalized for a closer examination of undiagnosed fever with mild headache. Despite lack of distinct findings on physical and laboratory examinations at admission, she suddenly developed anuresis due to acontractile neurogenic bladder. On the basis of her symptoms and the faint nuchal rigidity revealed later, as well as the results of cerebrospinal fluid analyses, a diagnosis of aseptic meningitis was eventually reached. While aseptic meningitis subsided within 3 weeks, about 10 weeks, including a 26-day period of anuria, was necessary for complete restoration of normal voiding function, necessitating intermittent self-catheterization. Acute urinary retention should be considered an uncommon but critical manifestation of aseptic meningitis.
