RATIONALELiver infarction caused only by hepatic artery occlusion is rare. Elevated levels of eosinophils in the blood and tissue can have devastating consequences.PATIENT CONCERNSMale, 21 years old, presented with persistent abdominal distension and discomfort for more than ten days without an apparent cause. Laboratory findings showed an eosinophil percentage of 32.5% (normal range 0.5%-5%). Computed tomographic angiography of the hepatic artery and its branches did not show any enhancement, only the common hepatic artery was visible.DIAGNOSISThe patient in this case had a peripheral blood eosinophil count of ≥1.5 × 109/L in multiple examinations over 6 months, and eosinophilic leukemia and secondary causes such as parasitic infections, allergic diseases, or tumors were ruled out, confirming the diagnosis of hypereosinophilic syndrome (HES).INTERVENTIONSThe patients were treated with interventional therapy, glucocorticoid pulse therapy and anti-infection therapy.OUTCOMESAfter interventional therapy, glucocorticoid pulse therapy, and anti-infection treatment, the patient was reexamined 2 months later. The CT scan showed that the range of the original infarction in the liver had shrunk compared to before, and the remaining liver had enlarged with good compensation; Laboratory tests improved compared with baseline: eosinophil percentage of 0.1%.LESSONSThis article discusses a rare case of hepatic artery occlusion and liver infarction in a young male patient with HES. The cause of hepatic artery embolism and hepatic infarction may be related to the abnormal increase in eosinophils, which can lead to hypercoagulation and thrombus formation. The article emphasizes the importance of timely diagnosis and treatment of HES to prevent life-threatening thrombotic events and describes the successful management of the patient condition through anticoagulation, anti-infection, liver protection, and glucocorticoid therapy.
