Abstract
- A 53-year-old woman with non-productive cough of unexplained aetiology for two years, developed a sub-acute symmetrical polyneuropathy involving all four limbs, accompanied by fever, cutaneous rash and myalgia in lower limbs. Laboratory studies revealed a leukocytosis with 70% eosinophils and excluded any cause for the hypereosinophilia. An echocardiogram showed increase in thickness of the atrial septum. Motor and sensory conduction velocity were reduced in ulnar and median nerve, and unrecordable in peroneal and tibial nerves. A sural nerve biopsy showed an axonal degeneration involving myelinated and unmyelinated fibers as well as a vasculitis with fibrinoid necrosis and perivascular infiltration of eosinophils. There was considerable clinical and laboratorial improvement with the use of steroids. The differential diagnosis between idiopathic hypereosinophilic syndrome and other disorders known to course with vasculitis and hypereosinophilia is discussed. Uma paciente de 53 anos de idade com tosse não produtiva de etiologia inexplicada durante dois anos desenvolveu polineuropatia subaguda envolvendo os quatro membros, acompanhada de febre, erupção cutânea e mialgia nos membros inferiores. Os estudos laboratoriais revelaram leucocitose com 70% de eosinófilos e excluiram qualquer causa para esta hipereosinofilia. Um ecocardiograma mostrou aumento da espessura do septo atrial. As velocidades de condução motora e sensitiva estavam reduzidas nos nervos ulnar e mediano e não foram registradas nos nervos tibial e fibular. A biópsia do nervo sural mostrou degeneração axonal envolvendo fibras mielínicas e amielínicas, assim como vasculite com necrose fibrinóide e infiltração perivascular de eosinófilos. Ocorreu considerável melhora com o uso de esteróide. O diagnóstico diferencial entre a síndrome hipereosinofílica idiopática e outras afecções que cursam com vasculite e hipereosinofilia é comentado.
