Eltrombopag-related renal vein thromboembolism in a patient with immune thrombocytopenia: A case report

Figure 1 Computed tomography studies of the abdomen and chest on admission, with enhancement (intravenous contrast). A and B: Abdominal computed tomography (CT) demonstrating a near-occlusive thrombus of the right renal vein (arrow) extending to the inferior vena cava; C and D: Enlargement of the right kidney on abdominal CT, with upper and lower poles showing poor perfusion; E: Chest CT with patchy infiltrates in lung window and right pleural effusion; F: Emboli of the right pulmonary artery (orange arrow) on chest CT.

Figure 2 Renovascular ultrasound obtained 1 wk later (after filter implantation) confirmed that the thrombus of the right renal vein had resolved. A: Retrievable permanent filter implanted within the inferior vena cava, cephalad to the renal vein; B and C: Renovascular ultrasound (1 wk post-implantation) confirming resolution of the right renal vein thrombus and normalization of kidney size.
