  • Title: A radiological and clinical description of metastatic angiosarcoma simulating a hydatid cyst.
    Author: Ortiz B, Hernández C, Barajas NC.
    Journal: Biomedica; 2019 Sep 01; 39(3):440-447. PubMed ID: 31584759.
    Abstract:
    Angiosarcoma is the most malignant sarcoma originating in endothelial vascular cells. It has a wide differential diagnosis due to its similarities with other entities, such as parasitic diseases. More often, angiosarcoma is diagnosed by exclusion. Neurocysticercosis and hydatid disease, or echinococcosis, are parasitic infections that may involve the central nervous system and their incidence is higher in South American countries. Diagnosis is established based on the epidemiological profile, the parasitological examination, the radiological appearance of the lesions, and the histopathology analysis of specimens. We present the case of a female adolescent with parasitosis risk factors whose neuroimages suggested cerebral hydatid cysts and who was finally diagnosed with cardiac metastatic angiosarcoma. Los angiosarcomas son sarcomas malignos que se originan en las células endoteliales vasculares. Su diagnóstico diferencial es muy amplio debido a su parecido con otras enfermedades, como las parasitarias, y usualmente es un diagnóstico por exclusión. La neurocisticercosis y la hidatidosis cerebral son parasitosis intestinales que pueden comprometer el sistema nervioso central y tienen mayor incidencia en los países suramericanos. El diagnóstico se establece a partir del perfil epidemiológico, el estudio parasitológico, la apariencia radiológica de las lesiones y el estudio de histopatología del espécimen. Se presenta el caso de una adolescente con factores de riesgo para parasitosis y neuroimágenes sugestivas de hidatidosis cerebral, cuyo diagnóstico definitivo fue angiosarcoma cardiaco metastásico.
