Pleural fluid having low glucose is seen in all, except?
Answer is A (None>Tuberculosis): Parapneumonic effusions (bacterial infections), Rheumatoid effusions, Malignant effusions (Mesothelioma) and Tuberculous effusions are all established causes that may present with low glucose (<60 mg/dl) in pleural Although tuberculosis may present with low glucose levels and is included in the differential diagnosis for conditions with low glucose in pleural fluid, the glucose levels in Tuberculosis is more often equal to serum levels. Tuberculosis is therefore the single best answer of exclusion amongst the options provided. Glucose levels in TB are usually equal to serum levels but Tuberculosis may present occasionally with Glucose < 60mg/d1- CMDT 09/277 According to Fishman's textbook on pulmonary disease, the presence of pleural fluid glucose below 60 mg/dl narrows the diagnostic possibilities to seven conditions. Conditions associated with Decreased Glucose (<60mg/dl) in pleural fluid Malignant Effusion (Also mentioned in Harrisons) Rheumatoid EffitsionQ (Also mentioned in Harrisons) Parapneumonic Effusion (Bacterial Infections as mentioned in Harrisons) Tuberculous EffitsionQ (Also mentioned in CMDT) Hemothorax Paragonimiasis Churg-Strauss Syndrome
