Benign symmetric lipomatosis(BSL) is a lesion characterized by symmetrical and diffuse growth of adipose tissue. It is commonly found in the posterior neck or upper trunk, manifesting itself as an entity known as Madelung disease or Lanoid-Bensaude syndrome. Lipomatosis affecting the tongue is very unusual. The etiology of BSL is unknown, but It can be associated with alcoholism, liver dysfunction, hypothyroidism. Because of its diffuse histologic feature, complete resection of the lesion is often difficult. Seventy one years old male patient, whose chief complaint was multiple nodules of tongue was referred to our department. The lesion was diagnosed histopathologically as BSL and subsequently removed surgically. So we report this rare case of BSL with literature review.

Metastatic tumors occur more frequently in the liver than in any other organ. Guided percutaneous fine-needle aspiration (FNA) of the liver is often recommended for confirmative diagnosis of the metastatic lesion, because of its simplicity, high yield, and reasonable safety. The authors studied retrospectively cytologic findings of 110 cases of metastatic tumors to the liver. The frequent primary sites were the stomach (23 cases), pancreas(19 cases), gallbladder(12 cases), and periampullary lesions(6 cases). Most of the metastases were carcinoma (106 cases). There were only 4 cases of sarcoma. The characteristic cytologic findings of FNA of meatastatic tumors were dirty background, abrupt change between hepatocytes and malignant cells, and desmoplasia. Some tumors displayed rather distinctive cytologic appearance that suggests primary sites. For example, the colonic adenocarcinoma showed tall columnar cells with a palisading arrangement, adenocarcinoma of gallbaldder showed focal squamous differentiation in some cases, and metastatic renal cell carcinoma and neuroblastoma showed also distinctive cytologic findings. Because the cytologic features of metastatic tumor are very similar to those of primary tumor, correct cytologic typing may be helpful in pursuit of an occult primary site of metastatic liver lesions, reducing extensive diagnostic investigation in poor prognostic patients.

Purpose: To compare the effectiveness of the in-phase (IP) sequence and the opposed-phase (Op) sequence in the detection of focal hepatic lesions in the single breath-hold hepatic MR imaging with fast gradient T1-weighted pulse sequences. Materials and Methods: IP and OP T1-weighted breath-hold imaging was performed using fast gradient echo sequences in 45 patients referred for known focal hepatic lesions, in which 78 lesions were detected. Three blind readers independently reviewed the images for lesion detectability. The signal-to-noise ratio (SNR) of the liver, the lesion-to-liver contrast-to-noise ratio (CNR) and the liver-to-spleen CNR were also compared. A consensus was reached by three readers to determine which sequence is better in image quality. Results: On OP images, 61(78%), 61(78%), and 63(89%) lesions were correctly identified for reader 1, 2 and 3, respectively. On IP images, 66(85%), 65(83%), and 65(93%) lesions were detected for each reader, respectively. When two image sets were combined, 71(91 %), 69(88 %), and 76(97%) lesions respectively were detected for each reader. In cases of hepatocellular carcinoma, liver-to-Iesion CNR was greater on the OP images(p (0.05), but in other lesions significant difference was not demonstrated. Liver-to-spleen CNR was higher on OP images(p ( 0.1), but the SNR of the liver was higher on the IP images. Conclusion: Use of both IP and OP imaging can be helpful to avoid erroneous missing of some focal hepatic lesions.

An abattoir survey of pneumonia and other lesions in slaughtered pigs from 5 selected herds located In the Western Kyongbuk was carried out during the period from March to December 1995. Pneumonic lungs was attempted bacteriological finding and antibiotic susceptibilities. From 583 slaughtered pigs, 445(76.3%) case was pneumonic lungs, seasonal patterns were Winter, Spring, Autumn, Summer in the order named. Among them, 127(21.8%) case was mycopla-sma pneumonia and 65(11.2%) case was pleuropneumonia. In snout lesion grade from 337 slaughtered pigs, above grade II score was 107(31.8%). In the white spot of liver, grade I was 544(93.3%), grade II32(5.5%) and grade III 7(1.2%). In the gastric ulcer, normal was 350(60.0%), grade I168(28.8%), grade II59(10.1%) and grade III 6(1.1%). Among the pigs(n=271) with pneumonic lesions above 20%, 162 strains werr isolated from 87(32.1%) pigs. The bacteria isolated from pneumonic lesions was Pasteurella sp 61(37.7%), Streptococcus sp 31(19.1%), Actinobacillus sp 3(1.9%), Coliform bacteria 19(11.7%) and the other bacteria 48(29.6%) These isolates were highly susceptible to the antibiotics including ENR 142(87.7%), Cft 138(85.2%) and Cf 126(77.8%).

Aim: This study aims to investigate the manifestation of CT, MRI and dynamic enhanced scans for primary hepatic neuroendocrine cell carcinoma. Methods: CT or MRI arterial and venous phase scan images of 19 cases of pathologically confirmed PHNEC were retrospectively analyzed. Results: 14 cases (73.68%) with single lesion, 5 cases (26.3%) with multiple lesions, with an average diameter of 13.2 cm. Some 12 cases (63.16%) showed inhomogeneous enhancement, seven cases (36.8%) showed homogeneous enhancement, 13 cases (68.4%) demonstrated significant enhancement in the arterial phase, 13 cases (68.4%) had significantly enhanced portal venous phase including 7 cases (36.8 %) with portal venous phase density or signal above the arterial phase and 5 cases (26.3%) with the portal vein density or signal below the arterial phase. Seven cases (36.8%) had continued strengthened separate shadows in the center of the lesion. Thrombosis were not seen in portal veins. Conclusion: CT and MRI images of liver cell neuroendocrine carcinoma have certain characteristics that can provide valuable information for diagnosis and differential diagnosis.

Background: The aim of this study was to investigate the value of serum gastric markers to differentiate between patients with precancerous lesions and nonatrophic chronic gastritis. Materials and Methods: Serum samples of 128 patients with dyspepsia who were candidates for endoscopic examination were tested for pepsinogen (PG I and PG II), PG I/II ratio, gastrin 17(G-17), anti-Helicobacter pylori (anti-H pylori ) and anti-CagA antibodies. Two sample t-tests, chi-square tests and Pearson's correlation analyses were used for analysis using SPSS (version 20). Results: PGI, PG I/II ratio values were decreased significantly in the precancerous lesion group (0.05, 0.001 respectively). The frequency of H pylori infection was significantly (p=0.03) different between the two groups ofthe study. Conclusions: We suggest PGI and the PG I/II ratio as valuable markers for screening of premalignant gastric lesions.

There have been reported numberous cases of liver scanning in use of $^{198}Au$ colloid by many investigators, however, one in use of $^{113m}In$ colloid has not been reported as yet in this country. The dose of $^{113m}In$ for high diagnostic value in examination of each organ was determined and the dignostic interpretability of liver scanning with the use of $^{113m}In$ was carefully evaluated in comparison with the results of the liver scanning by the conventionally applied radioisotopes. The comparative study of both figures of liver scannings with the use of $^{113m}In$ colloid and $^{198}Au$ colloid delivered following results: 1. The liver uptake rate and clearance into peripheral blood were accentuated more in case of $^{113m}In$ colloid than in case of $^{198}Au$ colloid. 2. The interpretability of space occupying lesion in liver scanning with $^{113m}In$ was also superior to one with $^{198}Au$. 3. The figure of liver scanning with $^{113m}In$ colloid corresponds not always to the figure with $^{198}Au$. This difference can be explained by differences of phagocytic ability of reticuloendotherial system within liver. 4. In the liver scanning with $^{113m}In$ colloid, the spleen is also visualized even in normal examinee. 5. In the cases of disturbed liver function, uptake is more decreased in use of $^{113m}In$ colloid than in $^{198}Au$, in the spleen, however, the way is contrary. 6. With use of $^{113m}In$ colloid, the time required for scanning could be shortened in comparison with $^{198}Au$. 7. The filtration of $^{113m}In$ colloid for scanning prior to human administration gives an expectation for better scanning figure.

Capillaria hepatica a primary trichuroid nematode parasite in rodents, has been reported in wide range of secondary hosts including humans. We report a rare case of Capillariasis in a 4-year old raccoon dog(Nyctereutes procyonoides) submitted to the Veterinary Diagnostic Laboratory Chonbuk National University for necropsy on July 5, 1996. Grossly the thoracic cavity contained approximately 200 mls of blood-tinged exudate. Edematous lesion was present around aorta and vena cava. liver was slightly swollen and mottled and contained multifocal yellowish-white lesions ranging from 1 to 3 mm in diameter. Histologically liver lesions were localized around central veins and were characterized by cell swelling and necrosis with mixed inflammatory cells surrounding parasite eggs. These eggs were barrel-shaped with polar caps consistent with Capillaria hepatica.

The role of scintigraphic imaging has moved from the detection of lesions to the tissue-specific characterization of lesions over the past 2 decades. Major advances in nuclear medicine imaging include: 1) positron imaging, 2) improved instrumentation, such as the use of multidetector (dual or triple head) gamma cameras for single photon emission computed tomography, and 3) development of numerous new radiopharmaceuticals for positron or single photon imaging (labeled glucose analogue, amino acids, fatty acids, hormones, drugs, receptor ligands, monoclonal antibodies, etc). These advances have resulted in a significantly improved efficacy of radionuclide techniques for the evaluation of various tumors, including those within the liver. The current role of nuclear medicine in the evaluation of focal hepatic tumors is reviewed in this article with an emphasis on the clinical applications of various tracer studies and imaging findings.
