BACKGROUND: Portal vein thrombosis (PVT) is complex and risk factors include local precipitating factors and acquired and inherited factors. It occurs secondary to abdominal malignancy, infection or surgical intervention. PVT is commonly forgotten as a possible cause of abdominal pain. The clinical picture may vary but abdominal pain and low grade fever are the most characteristic picture.
METHODS: A 58-year- old male patient was admitted to our hospital complaining of abdominal pain for three days. CT scan revealed an edematous area around the portal vein. Doppler ultrasonography showed evidence of a portal vein thrombosis.
RESULTS: PVT can be diagnosed with CT and Doppler ultrasonography. Fresh thrombus can be undetected by sonography because of the low echogenity but can be recognised by color Doppler ultrasonography. Treatment ranges from observation and bowel rest to surgical resection of bowel.
CONCLUSIONS: When we suspect a case of PVT, it should be treated at an early stage to prevent being lost in a diagnostic dilemma. The immediate use of anticoagulant could be important in preventing serious consequences of PVT.
