الإجابة: B. Tuberculosis
A serous, lymphocyte-predominant (exudative) effusion in a young woman is typical of tuberculous pleurisy. Parapneumonic effusions are neutrophilic. CHF and hepatic hydrothorax produce transudates with few cells.

ليش غلط
Parapneumonic effusion follows pneumonia and presents with fever, chills, cough and sputum. This woman has only progressive dyspnea, and the fluid is lymphocytic, not purulent.

TB effusion is a serous, amber exudate with lymphocytes predominating (adenosine deaminase raised, positive pleural biopsy).

C
ليش غلط
Cardiac failure gives a serous, straw-coloured transudate with few cells, not a lymphocyte-predominant exudate.

D
ليش غلط
Hepatic hydrothorax is a transudate due to cirrhosis and portal hypertension; it does not explain lymphocyte-predominant fluid, and nothing here suggests liver disease.
