Table 1

Summary of extensive workup that was done to investigate etiology of portal vein thrombosis in our patient. It includes three disease categories that are most commonly associated with development of PVT. All listed laboratory tests were either negative or the values were within normal limits.

Prothrombic disorders (inherited and acquired)	Occult malignancy	Cirrhosis
JAK 2 V617 F mutation; Fibrinogen; Thrombin time; Protein C levels; Protein S levels; Factor V Leiden mutation; ANA; PTT; Anti-β2 glycoprotein antibodies; Antithrombin functional activity; Lupus anticoagulant; Anticariolipin antibodies	CEA; CA-19- 9; AFP; PSA; Abdominal CT scan; Abdominal MRI	Platelets; INR; Albumin; Total bilirubin; Abdominal US; Abdominal CT scan; Abdominal MRI; HBV antigen and antibodies; HCV antibodies

AFP, alfa-fetoprotein; ANA, anti-nuclear antibodies; CA, carbohydrate antigen; CEA, carcinoembryonic antigen; CT, computed tomography; HBC, hepatitis B virus; HCV, hepatitis C virus; INR, international normalized ratio; MRI, magnetic resonance imaging; PSA, prostate specific antigen; PTT, partial thromboplastin time; US, ultrasound. The values of these tests might not be accurate during the acute phase of thrombosis.
