Tounderstand a series of eponymous diseases affecting the chestthrough the provision ofa brief vignette of the person, salient clinical features and imaging characteristics.

Many eponymous conditions exist in medicine. There is a general trend to move away from their use, characterising disease based on pathology and treatment response with many subtypes and variants being discovered. Eponymous terms are still of particular use in radiology, often in fellowship exams by easily illustrating complexity and fundamental principles. In addition, they are commonly used in discussions between radiology and non-radiology colleagues. Thus, an understanding of eponymous conditions and their origin is important. Furthermore they often provide interesting insights into how these...

Churg-Strauss syndrome Named after American pathologists Jacob Churg and Lotte Strauss. They presented the histological criteria of the syndrome in the American Journal of Pathology in 1951, based on 13 cases originally diagnosed with polyarteritis nodosa. Clinical features Autoimmune condition affecting asthmatics. Characterised by hypereosinophilia in the blood and tissues and is therefore now known as eosinophilic granulomatosis with polyangiitis. Small to medium vessel necrotising pulmonary vasculitis. Other features include sinusitis, diarrhoea, purpura, and joint pains. Association with pANCA. Imaging characteristics Parenchymal consolidation/ground glass. Pulmonary...
