RESUMEN
Hydatid disease is commonly encountered in specific geographic areas of the world. Hydatidosis affects multiple organs and has diverse radiologic presentations. Sonography remains an important modality for diagnosing this condition, as it optimally detects cystic structures, floating membranes, and debris. Sonography forms the crux of radiologic diagnosis of hydatid disease. It not only helps diagnose the disease but also aids in guiding therapeutic interventions. The main objective of this article is to describe the imaging features of hydatid disease in its various stages. This article gives an overview of the spectrum of sonographic manifestations of hydatid disease in various locations, along with common differential diagnoses. A brief description of therapeutic management is also presented.

RESUMEN
Tuberculosis (TB) remains a global threat, with the rise of multiple and extensively drug resistant TB posing additional challenges. The International health community has set various 5-yearly targets for TB elimination: mathematical modelling suggests that a 2050 target is feasible with a strategy combining better diagnostics, drugs, and vaccines to detect and treat both latent and active infection. The availability of rapid and highly sensitive diagnostic tools (Gene-Xpert, TB-Quick) will vastly facilitate population-level identification of TB (including rifampicin resistance and through it, multi-drug-resistant TB). Basic-research advances have illuminated molecular mechanisms in TB, including the protective role of Vitamin D. Also, Mycobacterium tuberculosis impairs the host immune response through epigenetic mechanisms (histone-binding modulation). Imaging will continue to be key, both for initial diagnosis and follow-up. We discuss advances in multiple imaging modalities to evaluate TB tissue changes, such as molecular imaging techniques (including pathogen-specific positron emission tomography imaging agents), non-invasive temporal monitoring, and computing enhancements to improve data acquisition and reduce scan times. Big data analysis and Artificial Intelligence (AI) algorithms, notably in the AI sub-field called "Deep Learning", can potentially increase the speed and accuracy of diagnosis. Additionally, Federated learning makes multi-institutional/multi-city AI-based collaborations possible without sharing identifiable patient data. More powerful hardware designs - e.g., Edge and Quantum Computing- will facilitate the role of computing applications in TB. However, "Artificial Intelligence needs real Intelligence to guide it!" To have maximal impact, AI must use a holistic approach that incorporates time tested human wisdom gained over decades from the full gamut of TB, i.e., key imaging and clinical parameters, including prognostic indicators, plus bacterial and epidemiologic data. We propose a similar holistic approach at the level of national/international policy formulation and implementation, to enable effective culmination of TB's endgame, summarizing it with the acronym "TB - REVISITED".
