Melioidosis varies from subclinical infection to fulminating disease with multiple organ involvement. Although endemic in South-East Asia and northern Australia, it may be imported into temperate zones. It is the wide spectrum of manifestation that makes it 'the great imitator'. The purpose of this pictorial essay is to familiarize the radiologist with the range of radiological manifestations of this disease. Intrathoracic findings include pulmonary nodules, consolidation, necrotizing lesions, pleural effusion, pleural thickening and mediastinal abscess. Abscess in almost all organ systems can be seen in the septicaemic and suppurative infections. Both clinical and radiological findings are non-specific. A high index of suspicion is required to focus the search for bacteriological confirmation. A prompt diagnosis is essential, as melioidosis is often rapidly fatal.
类鼻疽病的表现范围从亚临床感染到累及多个器官的暴发性疾病不等。尽管在东南亚和澳大利亚北部为地方病，但它可能传入温带地区。正是其广泛的表现使其成为“伟大的模仿者”。这篇图文并茂的文章旨在使放射科医生熟悉这种疾病的各种放射学表现。胸部表现包括肺结节、实变、坏死性病变、胸腔积液、胸膜增厚和纵隔脓肿。在败血症和化脓性感染中可见几乎所有器官系统的脓肿。临床和放射学表现均无特异性。需要高度怀疑才能有针对性地进行细菌学确诊检查。及时诊断至关重要，因为类鼻疽病往往迅速致命。
