Considering her clinical profile, her age and smoking
status, lung cancer
cannot be ruled out especially if the pleural fluid has re-accumulated in a short time. You need to get the consultation of a pulmonologist. A pleural biopsy (either blind or through thoracoscopy
) can be done, pleural fluid investigations should be sent and if required bronchoscopy
can be done. Only after the results of investigations are available will the picture be more clear. Normally infective effusions do not recur in such a short duration.
