Abstract
A 51-year-old male patient presented with breathlessness for 10 days. Chest radiograph revealed bilateral moderate pleural effusion. Ultrasound-guided diagnostic pleural aspirate revealed sterile transudative fluid. CT thorax revealed bilateral moderate pleural effusion with partial collapse of both lower lobes and thrombus in right brachiocephalic vein. Two-dimensional-echo revealed circumferential pericardial effusion with mild pericardial thickening and moderate tricuspid regurgitation. Cardiolipin antibodies were within normal limits. d-Dimer assay and C reactive protein were markedly raised. During the period of investigations, the patient had developed mild swelling and pain in right upper limb for which colour Doppler ultrasonography of his right upper limb and neck regions were done. Thrombi in right internal jugular, subclavian and brachiocephalic veins were noted. CT angiography, CT abdomen and chest confirmed the above findings. However, extent of the thrombus and lung lesions was better delineated by CT angiography. We have highlighted the pathognomonic imaging findings of Lemierre syndrome.
