A 7-year-old spayed female Somali-cross cat was admitted with a 4-week history of anorexia, vomiting, weight loss, and lethargy. The cat was diagnosed with hepatic lipidosis. With intensive care and nutritional support via a nasogastric feeding tube for 3 weeks, the clinical signs of hepatic lipidosis were improved. However, skin lesions were found in the left and right scapular regions during the treatment that were suspected to be due to feline skin fragility syndrome (FSFS). Intensive wound healing therapy with granulated sugar, laser therapy, and a surgical flap was conducted. Skin lesions improved uneventfully without other clinical signs or recurrence of any skin lesion for a year. To our knowledge, this is the first report of a good prognosis in a hepatic disorder and concurrent FSFS.

We report the radiological findings of regional enhancement of the liver adjacent to the right adrenal pheochromocytoma. CT and MRI showed focal strong enhancement of adjacent liver tissue in the arterial phase. However during the delayed phase, the lesion showed iso-attenuation with normal hepatic parenchyma and not delineated. The lesion did not show abnormal signal intensity on neither T1 nor T2 weighted images and indistinguishable from normal parenchyma. The enhancing hepatic lesion was spontaneously regressed on postoperative follow up CT which was taken several months after the adrenalectomy.

The purpose of this study was to characterize focal hepatic lesions through pre and post ferucarbotran-enhanced T2 and T2＊-weighted imaging and to help differentiate benign and malignant lesions 대상 및 방법： Consecutive 34 patients with 52 hepatic lesions underwent MRI before and after intravenous bolus injection of ferucarbotran (Resovist Sobering, Berlin, Germany) for evaluation of focal hepatic lesions. Lesions included hemangiomas (n=17), metastases (n=12), cysts (n=10), hepatocellular carcinomas (n=8), dysplastic nodules (n=4), and focal fat deposit (n=1). T2-weighted fast spin echo (TR/TE： 4060/138) and gradient echo T2＊-weighted images(TR/TE： 140/5.3, FA = 90) were obtained according to the institutional routine imaging protocol. Lesional signal-intensity and lesion-to-liver contrast changes were measured by contrast-to-noise ratio (CNR) from region of interest.

Hepatic encephalophthy was diagnosed with serum chemistry, abdominal radiography and ultrasonography in a 2.6kg, 4 year-old maltese dog showing signs of hypersalivation, involutary spasm of facial muscles, ataxia, behavior abnormalities like dullness, sleep disorder, restlessness. In serum chemistry, the level of alanine transferase and aspartate trasferase was mildly elevated, ammonia was severely increased. On abdominal radio-graphs, the size of liver was mildly decreased. In ultrasonographic examination, diffuse lesion with hyperechoic change and decreased vasculature were seen in the hepatic region. But vascular abnormalities of liver were not observed. Drug and dietary therapy were undertaken and severities of clinical sign were alleviated.

We present two cases of solitary necrotic nodules of the liver which on radiologic images mimicked hepatic metastasis. Solitary necrotic nodule of the liver is a rare but benign entity which histopathologically consists of an outer fibrotic capsule with inflammatory cells and a central core of amorphous necrotic material. The lesion was seen on contrast-enhanced CT as an ovoid-shaped hypoattenuating nodule; on CT during hepatic arteriography as enhancing nodule; on intraoperative US as a target-appearing hypoechoic nodule; on T2WI as a hyperintensity nodule, and on dynamic MR as a subtle peripheral enhancing nodule. Although the radiologic features are not specific, solitary necrotic nodule of the liver should be included in the differential diagnosis of hepatic metastasis.

Authors analyzed sonographic findings of 59 cases of hepatic hemangioma, with had been diagnosed through examination in our Medical. dept, from Januray, 1985 to December 1989. The results of the analysis are as follows: 1) The hepatic hemangioma was found in 59 cases(0.33%) among the 17,714 insureds. 2) In all 59 cases who have hemangioma, hemangioma was found in 37 cases(0.35%) among the 10,724 insureds of male, and in 22 cases(0.31%) among the 6,990 insureds of female. 3) The possessing rate of hemangioma in male was increased by age regardless of sex-5/2,120 cases(0.24%) in $21{\sim}30$ years, 25/8,122 cases(0.31%) in $31{\sim}40$ years, 16/4,997 cases(0.32%) in $41{\sim}50$ years, 8/1,775 cases(0.45%) in $51{\sim}60$ years, and 5/359 cases(1.39%) in over 61 years. 4) The tumor involved right lobe of the liver in majority(71.4%) 5) The size of tumor was 10 lesions in under 10 mm, 58 lesions in $31{\sim}50$ mm, and 6 lesions in over 51 mm. The smallest tumor was 8 mm in diameter and the largest was 72 mm in diameter and 78 lesion(92.8%) were less than 50 mm in size. 6) Posterior acoustic enhancement was noted in 4 lesions among 68 lesions of less than 30 mm in long diameter, and in 4 lesions among 16 lesions more than 30 mm in long diameter. 7) Echographically most of the lesions presented as a round or oval high homogeneous echogenic mass, although a few mass appeared to be hypoechoic or Mixed echogenic. Finally a small round echogenic, sharply-marginated and internally homogeneous lesion is highly suggestive of hemangioma. If the hypoechoic lesion has homogeneous internal echoes and/or strong marginal echoes, it is also suggestive of hemangioma.

Objective: To investigate the efficacy of gadobenate dimeglumine (GdBOPTA) enhanced MR imaging for the detection of liver lesions in patients with primary malignant hepatic neoplasms. Materials and Methods: Thirty-one patients with histologically proven primary malignancy of the liver were evaluated before and after administration of GdBOPTA at dose 0.05 or 0.10 mmol/kg. T1-weighted spin echo (T1W-SE) and gradient echo (T1W-GRE) images were evaluated for lesion number, location, size and confidence by three off-site independent reviewers and the findings were compared to reference standard imaging (intraoperative ultrasound, computed tomography during arterial portography or lipiodol computed tomography). Results were analyzed for significance using a two-sided McNemar's test. Results: More lesions were identified on Gd-BOPTA enhanced images than on unenhanced images and there was no significant difference in lesion detection between either concentration. The largest benefit was in detection of lesions under 1 cm in size (7 to 21, 9 to 15, 16 to 18 for reviewers A, B, C respectively). In 68% of the patients with more than one lesion, Gd-BOPTA increased the number of lesions detected. Conclusion: Liver MR imaging after Gd-BOPTA increases the detection of liver lesions in patients with primary malignant hepatic neoplasm.

Four water monitors at Zoological Garden, Chang Gyeong Won, Seoul, died within a week after signs of anorexia, lethargy, and discharge from eyes, nasal and oral cavities. The autopsy findings of the four animals were similar. As a main lesion, the liver was congested and diffuse necrosis was observed. The terminal portions of the rectum were studded with numerous small ulcers causing rectal stenosis. Histopathologically, massive hepatic necrosis preceded by fatty changes were evident. The rectal lesions manifested coagulative necrosis and thrombosis in the mucosa and submucosa.

Majority of hepatocellular carcinoma is evolved from a well differentiated cancerous condition such as hyperplastic lesions eg. adenomatous hyperplasia in cirrhotic liver or de no vo carcinogenesis and prolifenation along with dedifferentiation. Adenomatous hyperplasia is may be seen in severe acute hepatic injury, like submassive hepatic necrosis, or in chronic liver diseases, particularly liver cirrhosis and it has recently attracted much interest from both clinicians and pathologists because it is regarded as a precursor lesion of hepatocellular carcinoma. Hepatic adenomatous hyperplasia resembling focal nodular hyperplasia might have developed from localized vascular changes associated with chronic liver disease, pre-existing arterial malformation and early stage of angiogenesis in hepatocarcinogenesis. We present a patient who developed hepatocellular carcinoma after hepatic artery ligation.
