Resumo

A suspeição está na base de uma investigação clínica completa, sendo de extrema importância a revisão dos casos clínicos nos quais não consigamos estabelecer um diagnóstico definitivo. Desta revisão surgem hipóteses diagnósticas que contemplam doenças raras, como a macroglobulinemia de Waldenstrom, doença linfoproliferativa de células tipo B, caracterizada por infiltração medular e produção de IgM monoclonal. Em 1% destas gamapatias são diagnosticadas formas biclonais. Apresentamos o caso clínico de um doente com 74 anos, internado em Outubro/04 por colecistite aguda, tendo os exames pré-operatórios revelado derrame pleu-ral bilateral. Durante o internamento foi feita minuciosa investigação etiológica, que foi contudo inconclusiva. Em Maio/05 foi internado, tendo sido submetido a talcagem pleural direita e a investigação clínica, também esta inconclusiva. Em Julho/05 foi reinternado num serviço de medicina interna, por anasarca e dor nos pés. Fez-se nova investigação e o diagnóstico final foi de macroglobulinemia de Waldenstrom.

Abstract

Clinical suspicion is the bedrock of a thorough clinical work-up, and a review of the clinical files with no definitive diagnosis is a must. Such a review can uncover rare diagnoses, such as Waldenstrom's macroglobulinaemia, a proliferative B-cell disease characterised by medular infiltration and monoclonocal IgM production. 1% of these are biclonal. We present a case of a 74 year old patient diagnosed in October 2004 with acute cholecystitis. Surgical evaluation revealed bilateral pleural effusion with an inconclusive aetiology. Patient underwent a right pleurodesis in May 2005 and the aetiology remained inconclusive. The third evaluation, in July 2005, led to a final diagnosis of Waldenstrom's macroglobulinaemia.
