Colangiopatía asociada a SIDA: Cuando la sola imagen no basta AIDS cholangiopathy: When images in isolation are not enough
Abstract
En pacientes infectados con VIH, el hígado y las vías biliares pueden presentar compromiso de distinta índole. Dentro de éstos, la colangiopatía asociada al SIDA se presenta con una sintomatología más bien inespecífica y habitualmente con recuentos de linfocitos T CD4 In HIV-infected patients, liver and biliary tract may be affected by different entities, such as AIDS-cholangiopathy, which is usually associated with CD4+T lymphocytes count below 100 cells/mm³ along with non-specific symptoms. Although imaging studies play a major diagnostic role they should always be evaluated according to patients clinical context. While ultrasound and CT scans provide relevant diagnostic information, specialized studies such as MRI and MRCP have become increasingly valuable due to their ability to demonstrate parietal as well as stenotic biliary changes. Despite ERCP remains the gold-standard for diagnosis of AIDS-related cholangiopathy, currently it is usually reserved to clearly exclude the presence of malignancy, or as a specific invasive therapeutic procedure, when indicated.
