Alveolar echinococcosis is a parasitic disease primarily invading the liver. Due to its aggressive nature, it invades the adjacent structures and can even metastasize to distant organs. The appearance of hepatic involvement on computed tomographic scan is characteristic, but not specific, with areas of calcification seen within a hypoenhancing mass. Although magnetic resonance imaging may better define the extent of the disease, it often misleads the radiologist, especially if the lesion is devoid of cystic component(s) and if it occurs in nonendemic areas. Knowledge of the imaging appearance may prompt serological evaluation and aid in making an early diagnosis and planning appropriate treatment of this uncommon fatal disease, especially in nonendemic areas.
肺泡型棘球蚴病是一种主要侵犯肝脏的寄生虫病。由于其侵袭性，它会侵犯邻近结构，甚至可转移至远处器官。计算机断层扫描显示的肝脏受累表现具有特征性，但不具有特异性，在低密度强化肿块内可见钙化区域。尽管磁共振成像可能能更好地确定疾病范围，但它常常误导放射科医生，尤其是当病变没有囊性成分且发生在非流行地区时。了解影像学表现可能会促使进行血清学评估，并有助于对这种罕见的致命疾病做出早期诊断和制定适当的治疗方案，特别是在非流行地区。
