Table 1. Imaging modalities and their findings‎.

CT, computed tomography; GI, gastrointestinal; HRCT, high-resolution computed tomography; IV, intravenous; IVC, inferior vena cava; MRI, magnetic resonance imaging

Modality	Findings
Upper GI endoscopy with biopsy	Normal esophagus, diffuse erosive gastropathy, and normal duodenum; biopsy of gastric mucosa showed features suggestive of mild reactive gastropathy; no Helicobacter pylori identified; no evidence of intestinal metaplasia, dysplasia, or malignancy seen
Chest X-ray	Filling of right costophrenic angle and evocative of pleural effusion, with no left pleural effusion
CT venogram	No evidence of venous thrombosis
Brain MRI	Empty sella syndrome with papilledema, probably in relation to intracranial hypertension; no evidence of thrombosis
HRCT of the chest without contrast	It marked right pleural effusion with consolidation, bilateral pleuroparenchymal process more at the right side of the infective aspect
Ultrasound of the abdomen	Partial thrombus within the intrahepatic portion of the IVC measuring about 5.5 cm, attenuating more than 80% of the IVC lumen, with mild hepatomegaly, mild gallbladder wall thickening, and mild ascites
CT of the chest, abdomen, and pelvis with IV contrast	Large intrahepatic IVC and non-occlusive thrombus extending to the left hepatic vein with enlarged, engorged liver: findings suggestive of Budd-Chiari syndrome
