Presentation: 2-3 months progressive cough and dyspnea, no fever, no chest pain, no weight loss. Good appetite, sleeping well.

CT (non-contrast, 11.05.2026): No mass, no lymphadenopathy. Right pleural effusion reaching 6cm with adjacent atelectasis. Right apical pleural thickening. Bilateral emphysematous changes.

Admission blood labs (11.05.2026):

WBC: 10.1 (slightly high)
CRP: 9.3 (ref <5)
LDH: 222 (normal)
D-dimer: 1.51 (high, ref 0-0.5)
INR: 1.52 (high)
APTT: 46.1 (high)
Procalcitonin: 0.05 (normal, low sepsis risk)
AFB sputum: negative

Pleural fluid - Day 1 (12.05.2026):

Glucose: 10 mg/dL
LDH: 1020 u/L - Albumin: 26 g/L
Protein: 63.8 g/L
ADA: 36.2 u/L (ref 0-30) → HIGH
Culture: no growth
RBC: 0
Total nucleated cells: 5630/uL

Blood labs after 2 days IV Tazobactam (13.05.2026):

LDH: 174 (dropped from 222, now normal)
CRP improving
Glucose: 88 (normal)

Treatment & discharge:

Diagnostic thoracentesis only, less than 1% of fluid drained
IV Tazobactam x2 days, no oral antibiotics on discharge
No chest tube inserted
Cytology pending 30-45 days
PET-CT planned
Discharge codes: C34.9 + J90

Questions:

Pleural glucose dropping from 10 to 1 mg/dL in one day with LDH >1000 - TB or malignancy or empyema?
ADA elevated on both days (36.2 and 35.7) with father dying of TB - does this point toward tuberculous pleuritis?
Negative cultures don't rule out TB since standard cultures don't grow TB - correct?
Differential cell count was unmeasurable on both days - does this change the picture?
Was it appropriate to discharge without chest tube drainage given glucose of 1 mg/dL?
How urgently should we push for drainage tomorrow?

Treatment:IV Tazobactam x2 days only. Doctor stated "there is infection." No culture sent (or not shared). No oral antibiotics on discharge. No ADA test done.

Discharge codes:C34.9 (unspecified lung malignancy) + J90. Cytology pending 30-45 days. PET-CT planned.

Mu questions

Pleural glucose 10 + LDH 1020 with no CT mass - does this point more toward empyema or malignancy?
Was it appropriate to stop antibiotics without oral continuation?
Should ADA have been tested to rule out TB?
Is 30-45 days for cytology acceptable in this situation?
How urgently should we pursue PET-CT privately?
