In 2001, eight small-sized dogs and three medium-sized dogs with or without clinical signs such as vomiting, dyspnea and enlargement of superficial lymph nodes were diagnosed as lymphoma by radiography, ultrasonography and cytology. Among them, six were female mainly over 7 years old and others were male around 4 years old. There were six cases of multicentric form lymphoma, three cases of mediastinal form, an alimentary and an extranodal form, respectively. Radiographic findings were enlarged cranial mediastinal lymph node, sternal lymph node, and tracheobronchial lymph nodes on thorax and hepatomegaly, splenomegaly, and enlarged sublumbar lymph nodes on abdomen. Ultrasonographic findings revealed enlarged abdominal lymph nodes and multifocal hypoechoic lesions on the liver. Especially, severe wall thickness of small bowel was observed in a dog with alimentary lymphoma. Three dogs were dead during chemotherapy, and three dogs were dead without any treatment. Three dogs did not return and two treated dog showed normal status. Radiography and ultrasonography, although not giving an final diagnosis for lymphoma, are useful for assessment and diagnosis of lymphoma.

A female, 14-year-old mixed dog weighing 4 kg and a female,8-year-old schnauzer dog weighing 6 kg showing vaginal discharges and vomiting for a few weeks were examined for the preoperative check of anterior cruciate ligament rupture and the recheck after the surgery of nephrectomy. There were no distinct abnormal signs except for the increased CBC at schnauzer dog on blood chemistry analysis. Radiographic and ultrasonographic findings were a large abdominal mass and a cyst-like hypoechogenic or anechogenic cavitary lesion on the ovary region. These findings were consistent with an ovarian cyst. Thereafter highly suspected ovarian cysts by diagnostic imaging were supported by high estrogen concentration on hormonal assay and the results of Pathologic examination as the unilateral ovarian cysts with secondary pyometra.

A female 8-year-old Pug weighing 7.3 kg and a female 10-year-old Maltese dog weighing 3.5 kg showing anorexia and vomiting for a few weeks were referred to Veterinary Medical leaching Hospital, Seoul National University. Radiographic findings were an enlarged right kidney in a pug dog and a radiopaque material on the right ureteral region lateral to the third lumbar vertebrae with indefinite right kidney contour in a Maltese dog, repectively. Excretory urography performed in a Pug dog revealed a poor opacified enlarged right kidney with absent of pelvic recesses and pelvic dilation with proximal ureteral dilation on contralateral kidney. Ultrasonographic findings were enlarged kidney with dilated pelvis and echogenic sediment within the medulla in both dogs and especially an engorged proximal ureter and a thin rim of functional renal tissue remains in a Maltese dog. Those diagnostic findings indicated high possibility of pyelonephritis and these were confirmed by pathologic examination. Radiography and ultrasonography, although not giving final diagnosis for pyelonephritis, are useful for assessment and diagnosis of pyelonephritis.

Inflammatory bowel disease and alimentary lymphoma are common gastrointestinal disorder in cats. More recently, ultrasonographic features associated with feline alimentary lymphoma has been recognized as a diffuse thickening of muscular layer of small intestine. We investigated correlation between thickening of muscular layer of small intestine and such disease. We found a significantly increased thickness of the muscular layer of small intestine in cats with lymphoma or IBD compared with healthy cats. When a muscularis to submucosa ratio > 1 and regional lymphadenopathy were found during ultrasonography on cats with gastrointestinal signs, full-thickness biopsy could be recommended to make sure presence confirmation of inflammatory bowel disease or alimentary lymphoma.

무릎 퉁김 현상의 원인 중에서 반달연골의 불안정에 의해서 발생하는 무릎 퉁김을 소개하는 논문은 드물며, 특히 실시간 초음파 소견을 소개한 논문도 드물다. 우리는 오른쪽 무릎에 직접적인 손상을 받은 후 무릎 퉁김이 발생한 79세 여자 환자를 보고하고자 하며, 절단된 오른쪽 내측 반달연골의 뒤뿔과 몸통의 앞위쪽 전위에 의해 발생한 퉁김현상을 실시간 초음파를 사용하여 확인하였다.

한선종은 땀샘에서 기원하는 종양으로 전형적으로 진피 및 피하층에 위치한다. 악성 한선종은 매우 드물다. 그리고, 보통 영상 검사 없이 수술적 절제 치료를 시행한다. 악성 한선종의 초음파 소견도 매우 드물게 보고되어 있다. 저자들은 악성 한선종의 초음파 소견을 보고하고자 한다.

This study was carried out to show at the fractal analysis complements the practical disadvantage of gray level histogram which is designed to measure the quantitative classification of echo patterns in ultrasonographic image of parenchymal organs such as spleen and kidney and it is a practical method of measurement for quantitative classification. By using ultrasonographs, kidney and spleen of 21 healthy Beagles were fixed under different gain settings to be scanned for echo patterns and results were analyzed with body gray level histogram and fractal analysis. Then it was compared based on the statistical data obtained. Although there was a proportionate increase in histogram along with gain settings, there were consistencies in the fractal dimension. In terms of quantitative analysis in ultrasonographic images, fractal analysis is concluded to complement the practical disadvantage of gray level histogram.
