Prolonged survival in a patient with disseminated malignant teratoma in the presence of a persistently elevated serum alpha-fetoprotein level.

The authors report a patient with disseminated malignant teratoma who has survived for 3.5 years after discontinuation of treatment despite a persistent and nonprogressive elevation of his serum alpha-fetoprotein level. Potential sources of the marker in his case are discussed and the possibility of a chemotherapeutically induced evolution of his tumor considered.

Functional aortic coarctation caused by thrombosis within a thoracic aortic aneurysm.

A 67 year old male arteriopath presented with chest pain, a new systolic murmur at the lower left sternal border and loss of leg pulses. Mitral regurgitation and ventricular septal defect were excluded by echocardiographic colour flow Doppler mapping and right heart catheterisation. CT scanning demonstrated a leaking aneurysm of the descending thoracic aorta with stenosis of the proximal lumen due to atheroma and thrombus causing a functional coarctation. The findings were confirmed at surgery.
