A twenty-one-year old man visited our hospital due to abdominal distension for a month. On the physical examination, there was severe abdominal distension with fluctuation and shifting dullness. The routine laboratory results were within normal range. On the Magnetic Resonace angiography, there wasnt any blood flow within the right and middle hepatic vein. So we concluded that the etiologic disease was Budd Chiari syndrome. On the Iiver scan, there was cold area(absence of radiouptake) on entire right lobe of the liver, increased uptake on the bone marrow and showed spienomegaly. This finding was similar to the liver mass occupying right lobe with underlying chronic liver disease. On the previous reports, it is quite uncommon finding that Budd-Chirari syndrome shows lesion like space occupying one on the liver scan. So we report this case with a review of the lit.erature.
