거대 해면상간혈관종 2예 = Giant Caverous Hemangiomas of the Liver

다국어 초록 (Multilingual Abstract)

Benign tumors of the liver are rare, and Henson and associates collected only 34 hemangiomas between 1907 and 1954 at the Mayo Clinic. Most of the cavernous hemangiomas of the liver are small in size, and produce no symptoms during life, but some can reach massive proportions and often present as abdominal masses or causes symptoms by encroachment on adjacent viscera. We have recently been confronted by two case of those large tumors, which has prompted this report with a review of this relatively rare condition. 1) A 32-year-old woman was admitted because of anorexia and indigestion associated with headache, myalgia, mild elevation of fever and weight loss of 5kg in two months. Examination of the abdomen disclosed one finger breadth palpable liver which was slightly tender. A large intrahepatic space-occupying lesion was discovered on radionuclide scan, ultrasonography and computed tomography of the abdomen. Selective hepatic angiography revealed characteristic features of puddling of contrast media along the branches of right and middle hepatic arteries throughout the arterial and venous phase of the angiograms. The resected specimen using Cavitron Ultrasonic Surgical Aspirator was proved to a giant cavernous hemangioma of the liver on microscopic exam. A 32-year-old man came to the hospital because of abdominal pain and a extremely huge mass nearly occupying the whole of his belly. The lesion was found to be a multiloculated highly echogenic mass in the left lobe of the liver on ultrasonography, and a huge hypodense, well-circumscribed homogeneous one with central low density component in the liver on computed tomography of the abdomen. Extensive pooling of contrast media was found throughout the markedly enlarged liver with persistence of tumor stain wliich was measured to be about 25cm in diameter until the late venous phase of the selective hepatic arteriograms. The tumor was considered to be an unresectable one, and we recommended radiation therapy.
