Isolated pulmonary cysticercosis is a rare manifestation of human cysticercosis which mainly affects central nervous system, skeletal muscles, eyes and subcutaneous tissues. Pulmonary involvement is usually a part of disseminated disease and mainly presents as bilateral pulmonary nodules. We report a rare case of isolated pulmonary cysticercosis presenting as lung cyst with pleural effusion. The diagnosis was made on pleural fluid cytology and cell block preparation. Herein we wish to recapitulate the importance of cell block as a diagnostic aid for parasitic infections, where morphological features and architectural patterns are as clearly discernable as in histopathology.

“细胞阻断”寄生冒名顶替者：孤立性肺囊尾蚴病的罕见病例

孤立性肺囊尾蚴病是人类囊尾蚴病的一种罕见表现，主要影响中枢神经系统、骨骼肌、眼睛和皮下组织。肺部受累通常是播散性疾病的一部分，主要表现为双侧肺部结节。我们报告一例罕见的孤立性肺囊虫病，表现为肺囊肿伴胸腔积液。根据胸水细胞学检查和细胞块制备做出诊断。在此，我们希望重申细胞块作为寄生虫感染诊断辅助的重要性，其中形态特征和结构模式与组织病理学一样清晰可辨。
