An 80-year-old male, nonsmoker, was admitted as a diagnosed case of sputum-positive pulmonary TB already on ATT for a week. Examination of the chest and abdomen was unremarkable. Peripheral edema of the right lower limb was found. The patient was confined to bed for most of his days at home and hospital in the last few months.
Chest X-ray demonstrated consolidation with associated collapse on the right upper lobe [Figure 5].
USG Doppler of the lower limb revealed sluggish flow with rouleaux formation with echogenic material, suggestive of thrombus in right popliteal vein with thickening of venous valves in both lower limbs [Figure 6].
ATT was continued and he was started on low-molecular-weight heparin (LMWH). He was not shifted to oral anticoagulants because of their poor safety profile as the patient was old and had unpredictable liver functions due to concurrent ATT. Patient responded to treatment and peripheral edema disappeared in 2 weeks' time. USG Doppler was repeated at 3rd week which demonstrated complete resolution of echogenic material.
