혈액 투석을 받고 있는 상염색체 우성 다낭성 신 질환 환자에서 에탄올을 이용한 신동맥 색전술은 신장 크기 증가로 인한 복부 팽만, 복통 등의 증상 완화에 비교적 안전하고 효과적인 치료 방법으로 생각되며 이전에 시행하였던 수술적 제거술, 경화 요법, 감압법 등을 대체할 수 있는 효과적인 방법으로 생각되어 문헌고찰과 함께 5예를 보고하는 바이다.

Sarcoidosis, systemic inflammatory disease characterized by non-caseating granulomas, is rarely associated with renal failure in a kidney transplant. We report a 51-year-old woman with a kidney transplant who was diagnosed to have renal sarcoidosis. After 7 years of renal transplantation, the patient presented with relatively rapid deterioration of renal function and, subsequently, she underwent kidney transplant biopsy. Renal biopsy revealed interstitial nephritis with non-caseating granulomas compatible with granulomatous interstitial nephritis (GIN). She was also found to have granulomatous lymphadenitis and skin lesions. Diagnosis of sarcoidosis was made based on histopathologic findings, the high serum angiotensin converting enzyme level and exclusions of other causes of GIN including tuberculosis, ANCA associated glomerulonephritis and tubulointerstitial nephritis and uveitis syndrome. The patient was started on oral prednisolone, and subsequently her renal function improved. (Korean J Med 2013; 84:290-294)

Renal vein thrombosis (RVT) is rare and primarily observed in children with severe dehydration or in adults in a hypercoagulable state. This diagnosis is rarely considered when it occurs in adults. We report a case of a young man who had weight loss of 8 kg in 2 weeks accompanied by dehydration with excessive exercise, and he developed a right RVT with a pulmonary thromboembolism. The man had a 3-year history of essential hypertension and was admitted to the hospital because of severe right-flank pain. A RVT and pulmonary thromboemboli were visualized by computed tomography. No abnormal results were observed on coagulation tests, and no evidence of malignancy was found. We concluded that the RVT and pulmonary thromboembolism were induced by dehydration. Even though the patient was an adult, rapid weight loss with dehydration may cause RVT and unusual thromboembolic events must be suspected to avoid a delay in the diagnosis.
