RESUMO
La hidatidosis es una parasitosis cuyo agente etiológico es el céstodo del género Echinococcus, siendo las especies más frecuentemente involucradas la E. granulosus y E. multilocularis. Puede afectar a cualquier órgano, aunque con mayor frecuencia se asocia a compromiso hepático y pulmonar. Los hallazgos imagenológicos clásicos en órganos habitualmente comprometidos están ampliamente descritos, no así en localizaciones poco comunes. Presentamos un caso de hidatidosis multiorgánica con compromiso peritoneal y pericárdico, estudiado con ultrasonido y tomografía computada, con revisión de la literatura actualmente disponible al respecto.
Abstract. Hydatidosis is a parasitic disease whose etiologic agent is the tapeworm of the genus Echinococ-cus, the species most frequently involved being E. granulosus and E. multilocularis. It can affect any organ, but most often is associated with liver and lung involvement. The classic imaging findings in organs that are usually involved are fully described, but not so for those in unusual locations. We report a case of multi-organ hydatidosis with peritoneal and pericardial commitment, studied with ultrasound and computed tomography, with a review of the currently available literature regarding this.

A shift from large to small average sizes was observed in Triatoma infestans and Rhodnius domesticus between field and domestic (or laboratory) conditions of life. It was more pronounced in the female specimens, leading to a subsequent reduction of sexual size dimorphism. This feature is discussed in terms of genetic and populational changes occurring from natural to artificial habitats, in particular those related to population densities. Sexual size dimorphism is then recommended as a new character to be used in the study of species of Triatominae adapting to domestic ecotopes
