A 70-year-old nondiabetic and nonsmoker woman from eastern district of Uttar Pradesh, India, was referred to our department as a case of right-sided pleural effusion cause? Tubercular. She was on antitubercular treatment (ATT) for the past one and a half month with no response in her complaints of fever, breathlessness, dry cough, and right-sided chest pain. At the time of presentation, she had low-grade continuous fever, breathlessness, and chest pain, which was in the lower part of the chest on the right side and increased on deep inspiration and coughing. On physical examination, she had reduced chest expansion, stony dull percussion, and reduced breath sounds on the right side. The rest of the examination was not contributory. Her repeat chest radiograph revealed right-sided pleural effusion [Figure 1]. She was investigated on the lines of nonresolving pleural effusion keeping the differential diagnosis of malignancy, collagen vascular disease, and tuberculosis in mind. Her routine blood investigations and biochemistry were within normal limits. The Mantoux test showed no induration. Three sputum specimens for acid fast bacilli were negative on direct smear examination. Antinuclear antibody and Antidouble stranded DNA antibody were not detected. Diagnostic thoracentesis revealed straw colored fluid. It was exudative (protein 4.2 g/dL and serum protein 7.0 g/dL) in nature with cytology showing 240 cells/mm 3 with lymphocytes 90%, eosinophils 05%, and neutrophils 05%. Adenosine deaminase of fluid had the value of 35.5 U/L (normal < 40 U/L). No acid fast bacilli or bacteria were seen on Ziehl-Neelsen and Gram stain, respectively. Polymerase chain reaction of fluid was negative for nontubercular mycobacterium and Mycobacterium tuberculosis. The pleural fluid was negative for malignant cells on four different occasions. During the examination of the fluid in the Neubauer chamber for the leukocyte count, our microbiologist noticed a single parasitic organism [Figure 2].
