Horton's aortitis.

Multiple thrombi in the ascending aorta: usefulness of contrast transesophageal echocardiography in a case of Horton's aortitis.

Fractal river networks, Horton's laws and Tokunaga cyclicity

The structure and scaling of river networks characterized using fractal dimensions related to Horton's laws is assessed. The Hortonian sealing framework is shown to be limited in that strict self similarity is only possible for structurally Hortonian networks. Dimension estimates using the Hortonian scaling system are biased and do not admit space filling. Tokunaga eyclicity presents an alterna...

Aortitis.

Aortitis is the all-encompassing term ascribed to inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitides giant cell arteritis (GCA) and Takayasu arteritis, although it also is associated with several other rheumatologic diseases. Infectious aortitis is a rare but potentially life-threatening disorder. In some cases, aortitis is an incidental finding at t...

Pleural effusion associated with aortitis syndrome.

A patient with aortitis syndrome had a pleural effusion which subsided but reappeared with an exacerbation of aortitis symptoms while under antituberculosis treatment. The character of the fluid was that of an exudate, and the glucose concentration was normal. Clinical and laboratory features of the case suggest that the effusion was part of the aortitis syndrome per se.

Mediastinal mass caused by syphilitic aortitis.

A 47 year old man presented with hoarseness and chest pain found to be due to proliferative syphilitic aortitis. The case is unusual as the syphilitic aortitis caused a mediastinal mass without affecting the lumen of the aorta.
