We report two cases of reversible left ventricular dysfunction associated with deep negative T waves during acute adrenal crisis due to isolated deficiency of adrenocorticotrophic hormone. There were no symptoms suggestive of heart disease in either case and left ventricular wall motion abnormalities, present mainly around the left ventricular apex, returned to normal in 1-2 weeks. Deep negative T waves normalized 4 weeks after corticosteroid administration. Acute adrenal crisis should be considered when deep negative T waves are associated with left ventricular dysfunction without cardiac symptoms.

Progression of Takayasu's aortitis was observed by serial angiography over 2 years. Acute aortic regurgitation due to marked dilatation of the proximal ascending aorta was followed by aneurysmal dilatation of the distal ascending aorta. Aneurysmal dilatation of the carotid arteries then developed, with subsequent obstruction of both the bilateral vessels by thrombosis.
