Pancreaticoblastoma is a rare nonfunctioning primary malignant neoplasm of the pancrease occuring in childhood. It arises in the ventral pancreas and is thought to be caused by a disturbance in organogenesis due to failure of the duct of Wirsung to communicate with the duct of Santorini and the ampulla. It is well-demarcated solid and cystic tumor on the basis of the gross morphology. Prognosis is known to be good if the tumor is discovered prior to metastasis. Authors present a case of pancreaticoblastoma in a 3 year-old girl with a brief review of the literatures.

연부조직의 스파르가눔증 (Sparganosis)

박기순 대한영상의학회 1993 대한영상의학회지 Vol.29 No.6

Sparganosis is a rare tissue-parasitic infestation caused by a plerocercoid tapeworm larva (sparganum), genus Spirometra. The common clinical presentation of sparganosis is a palpable subcutaneous mass or masses. Fifteen simple radiographs and 10 ultrasonograms of 17 patients with operatively verified subcutaneous sparganosis were retrospectively analyzed to find its radiologic characteristics for preoperative diagnosis of sparganosis. The locations of the subcutaneous sparganosis were lower extremity, abdominal wall, breast, inguinal region and scrotum in order of frequency. The simple radiographs showed linear or elongated calcifications with or without nodular elongated shaped soft tissue mass shadows in 8 patients, soft tissue mass shadow only in 2 patients and lateral abdominal wall thickening in 1 patient. But no specific findings was noted in 4 patients with small abdominal and inguinal masses. We could classify the subcutaneous sparganosis by ultrasound into 2 types: one is olng band-like hypoechoic structures, correspondingto the subcutaneous tunnel-like tracks formed by migration of sparganum larva and the other is elongated or ovoid hypoechoic nodules, representing granulomas. Long band-like hypoechoic structures sithin or associated with mixed echoic granulomatous masses were noted in 6 patients and elongated or ovoid hypoechoic mass or masses were noted in 4 patients. In conclusion, sparganosis should be considered when these radiologic findings-irregular linear calcifications on simple radiograph and long band-like hypoechoic structures on ultrasonography, corresponding to the subcutaneous tunnel-like tracks formed by migration of sparganum larva-are noted in the patients who have subcutaneous palpable mass or masses. And radiologic examination especially ultrasonography is very helpful to diagnose spargnosis.

음경의 경화성 림프관염 : 증례보고

Sclerosing lymphangitis of the penis occurs as a skin-colored or dusty red, cord-like thickening of tissue at the corona or within the coronal sulcus. The thickened, elongated lesion is firm and relatively nontender. The cause is unknown : because it occurs primarily in those who are sexually very active, however, it is likely that chronic trauma palys an important etiologic role. We experienced a case of pathologically proven sclerosing lymphangitis in a 31 year-old man. Ultrasonographic finding showed circumferential cord like hypoechoic band with irregular, but well demarcated margin.

Diatrizoated의 농도 및 삼투압 차이에 따른 백서 신손상에 관한 연구

There has been few papers regarding the pathologic changes of kidney induced by contrast media, especially in terms of iodine concentration or osmolarity. In order to evaluate histopathologic changes, a series of rat kidneys, after injection of iodinated contrast media, were examined. A total of 220 rats were divided into two groups: those given Urografin-60% by 6.3ml/Kg(1840mg/6.3ml); those given Urografin-76% by 5ml/Kg(1850/5ml). (the same amount of iodine but at different iodine concentration). The kidneys were removed and microscopically examined on 1, 2, 3, 5, 7, 10th days, 2nd, 3rd, 4th, 6th and 12th weeks after injection of contrast media, respectively. The results were as follows:Renal pathologic changes induced by contrast media were congestion and ectatic change of the interstitial vessels, and epithelial degeneration and necrosis of the collecting ducts. Congestion of interstisial vessels and epithelial degeneration and necrosis of the collecting ducts were severe i the higher iodine concentration Urografin-76% group(2100 Osm/Kg H2O) than the Urografin-60% group(1500 Osm/Kg H2O). And above pathological changes persisted for 12weeks without significant interval changes. The authors conclude that the renal damage induced by ionic contrast media becomes more severe in higher concentrations or osmolarities in spite of the same amount of iodine and that the pathologic changes persisted until 12weeks without improvement.

Hepatic infarct is relatively rare and uncommonly diagnosed before autopsy. We experienced a case of hepatic infarct involving the left lobe of the liver. The early findings of the lesion appeared hypoechoic on ultrasonography(US), and poorly demarcated low density on computed tomography. The lesion became more distinctly marginated. Finally, the involved left lobe of the liver was atrophied.

Omental cake is defined as a pancake-like diffuse thickening of the greater omentum stretching from the greater curvature of the stomach down to the lower abdomen. The causes of omental cake are metastatic ab-dominal tumor mesothelioma and peritonitis. The authors evaluated the sonographic findings of omental cakes in 29 patients with metastatic cancer and 17 patients with bacterial or tuberculous peritonitis. Omental cakes were diffuse (78%) or localized (22%) hyperechoic(78%) or heterogenous echogenic (22%) and irregular or smooth. There was no differential point between malignant tumor and inflammation. The authors stress that a radiologist should be alert to detect an omental cake as a staging work-up in patients with cancer or peritoneal infalmmatory disease.

Extrauterine, nongestational choriocarcinoma is uncommon. Most cases arise in the gonads, mediastinum or retroperitoneum with a striking male predilection. Although the lungs are a frequent site of metastatic choriocarcinoma, primary choriocarcinoma of the lung is extremely rare. Recently we experienced a case of primary choriocarcinoma of lung in 28-year-old female. So we report the case with review of literature including radiologic findings.

본 논문은 지하에 엄폐된 군사적 목표에 대한 효과적 타격 수단으로써 군사적 중요성이 부각되고 있는 장거리공대지 정밀유도무기에 대하여 체계 운용개념, 체계 구성 및 특성을 분석하였고, 장거리공대지 정밀유도무기 국산화 개발에 필요한 기술적 요소를 도출하였다. 국내의 장거리공대지 국산화 개발 기술수준은 대공/대지/대함 등의 유도무기의 국내개발 과정에서 획득한 기술능력을 기반으로 선진국 수준에 근접해 있으며, 이를 바탕으로 장거리공대지 유도무기 국산화 개발이 가능함을 보였다. 또한 장거리공대지 국산화 개발 전략으로 국내 유도무기 개발 시 확보한 기술의 효율적 활용을 통한 개발 방안을 제시하였고, 유사무기 체계 개발 시 유발된 경제효과를 기준으로 장거리공대지 국산화에 따른 경제유발효과를 분석하였다. The acquisition of LRASM(Long Range Air to Surface Missile) is urgent issue in South Korea because of North Korea’s 8,200 number of underground nuclear, biochemical and canon military facilities. South Korea needs effective means of attack for these underground military facilities, and has a acquisition prospect of LRASM. South Korea has acquired system and component technology needed for LRSAM development through various type precision guided missile system development, and reached technical level of LRASM system development. This paper analyzed configuration and operational concept for LRASM, and extracted the technical component for LRASM development. This paper also suggested effective developmental strategy for LRASM by using acquired missile technology, and analyzed economic effect of LRASM development.
