Hypereosinophilic syndrome is a rare hematologic disorder with sustained eosinophilia. Peripheral blood eosinophilia without an underlying etiology and with organs dysfunction has been designated hypereosinophilic syndrome. We report a rare case of symptomatic spinal infiltration of eosinophils at osteolytic T5 in patient with idiopathic hypereosinophilic syndrome.

Objective: The purpose of this study was to describe the CT findings of hepatic hypereosinophilic syndrome in which hepatic lobes or segments were involved. Materials and Methods: Seven patients with hypereosinophilic syndrome with hepatic lobar or segmental involvement were included in our study. In all seven, diagnosis was based on liver biopsy and the results of corticosteroid treatment. CT findings were retrospectively reviewed by three radiologists, who reached a consensus. Biopsy specimens were examined, with special reference to portal and periportal inflammation. Results: CT demonstrated well-defined, homogeneous or heterogeneous low attenuation with a straight margin limited to a hepatic lobe (n = 2), segments (n = 3), or subsegments (n = 2), particularly during the portal phase. Where there was subsegmental involvement, lesions were multiple, ovoid or wedge-shaped, and showed low attenuation. In two patients with lobar or segmental involvement, segmental portal vein narrowing was observed. Histopathologic examination disclosed eosinophilic infiltration in the periportal area, sinusoids and central veins, as well as portal phlebitis. Conclusion: Hypereosinophilic syndrome may involve the presence of hepatic lobar, segmental, or subsegmental low-attenuated lesions, as seen on CT images. Their presence may be related to damage of the liver parenchyma and to portal phlebitis.

특발성 과호산구 증후군은 호산구 매개에 의한 조직 손상으로 인해 다발성 장기부전, 특히 심장을 침범하는 드문 전신성, 백혈구증식성 질환이다. 심장침범은 특발성 과호산구 증후군 환자의 75% 이상에서 일어난다. 심장증상은 심내막 하 섬유증, 제한성 심근병증, 판막부전, 그리고 말초동맥 혈전증을 유발하는 혈전이다. 이 질환은 남자에서 여자보다 9 : 1로 호발하고, $20{\sim}50$대에서 주로 발현하는 경향이 있으며 소아에서는 매우 드물다. 인공 대동맥판막부전을 나타낸 특발성 과호산구 증후군 환자(58세, 남자)를 인공판막 재치환 수술 후 부신피질호르몬제와 hydroxyurea 투여로 성공적으로 치료하였기에 보고하는 바이다.

Bronchoalveolar lavage (BAL) has emerged as a useful technique for the study of pulmonary interstitial disorders. Several types of Information are provided by the evaluation of lavage fluid identification of cellular constituents helps to separate inflammatory process. Recently we have studied cellular constituents of BAL from three cases with histologically confirmed pulmonary sarcoidosis, idiopathic pulmonary fibrosis and hypereosinophilic syndrome. Pulmonary sarcoidosis showed a marked increase in lymphocytes, idiopathic pulmonary fibrosis revealed a predominance of neutrophils, and hypereosinophilic syndrome presented a marked increase in eosinophils in the lavage fluids.

Hypereosinophilic syndrome (HES) is characterized by the presense of hypereosinophilia with evidence of target organ damage. We report a patient diagnosed with eosinophilic cystitis and HES. A 7 year old boy had hematuria, dysuria, and increased urinary frequency for 1 day. Laboratory examinations revealed hypereosinophilia (eosinophils, $2,058/{\mu}L$), hematuria, and proteinuria. Abdominal sonography revealed diffuse and severe wall thickening of the bladder. The patient was treated initially with antibiotics. However, his symptoms did not improve after 7 days. A computed tomography scan demonstrated severe wall thickening of the bladder and the hypereosinophilia persisted (eosinophils, $2,985/{\mu}L$). The patient complained of chest discomfort, dyspnea, epigastric pain, and vomiting on hospital day 10. Parasitic, allergic, malignancy, rheumatologic, and immune workups revealed no abnormal findings. Chest X-rays, electrocardiography, and a pulmonary function test were normal; however, the hypereosinophilia was aggravated (eosinophils, $3,934/{\mu}L$). Oral deflazacort was administered. A cystoscopic biopsy showed chronic inflammation with eosinophilic infiltration. The patient's respiratory, gastrointestinal, and urinary symptoms improved after 6 days of steroids, and he was discharged. The eosinophil count decreased dramatically ($182/{\mu}L$). The hypereosinophilia waxed and waned for 7 months, and the oral steroids were tapered and stopped. This case describes a patient diagnosed with eosinophilic cystitis and HES.

A 39-year-old man presented with cough, chest discomfort, and weight loss. On the basis of the patient history and laboratory findings, he was diagnosed with the hypereosinophilic syndrome. Transthoracic echocardiography revealed a large thrombus in the left ventricle. Medical treatment with anticoagulation and immunosuppression was commenced immediately. Fourteen days after the initial diagnosis, the patient presented with acute pain in his right leg. Computed tomographic angiogram showed embolic occlusion of the infrarenal abdominal aorta and bilateral iliac (including common, external, and internal iliac) arteries. Emergent thromboembolectomy and left ventricular thrombectomy were performed. The postoperative course was uneventful, and the patient has undergone follow-up for 2 months without any evidence of recurrence of thromboembolism.

We report here a case of strongyloidiasis in a 72-year-old diabetic patient (woman) accompanied by gastrointestinal stromal tumor receiving imatinib therapy, first diagnosed as hypereosinophilic syndrome and treated with steroids for uncontrolled eosinophilia. She suffered from lower back pain and intermittent abdominal discomfort with nausea and diagnosed with gastrointestinal stromal tumor. After post-operative imatinib treatment eosinophilia persisted, so that steroid therapy was started under an impression of hypereosinophilic syndrome. In spite of 6 months steroid therapy, eosinophilia persisted. Stool examination was performed to rule out intestinal helminth infections. Rhabditoid larvae of Strongyloides stercoralis were detected and the patient was diagnosed as strongyloidiasis. This diagnosis was confirmed again by PCR. The patient was treated with albendazole for 14 days and her abdominal pain and diarrhea improved. This case highlights the need for thorough investigation, including molecular approaches, to test for strongyloidiasis before and during steroid therapies.
