Clinical and pathological analysis of solitary fibrous tumors with portal vein widening: A case report

RATIONALE: Solitary fibrous tumors (SFTs) are rare soft-tissue tumors characterized with spindle-cell, which occur more common in the chest and rarely seen in the abdomen. So far as we knew, SFTs accompanied with venopathy of portal vein has rarely been reported. PATIENT CONCERNS: A 36-year-old male presented with left-sided abdominal mass and portal vein expansion on ultrasound. DIAGNOSES: The post-operative histopathology confirmed the diagnosis of Solitary fibrous tumor. INTERVENTIONS: Laparotomy was performed and the mass was completely removed. OUTCOMES: Patients had no symptoms, recovered well without recurrence; the portal vein and splenic vein dilatation were alleviated and the symptoms of portal hypertension were relieved. LESSONS: SFTs presents with few symptoms in the early stage of the disease. A rich arteriovenous shunt is beneficial to the diagnosis of SFTs by B-ultrasound and computed tomography (CT) examinations. However, the diagnosis of SFTs must depend on histopathology.
