Multiple species of muridae and arvicolidae rodents serve as the natural reserviors of hantaviruses. Hantaviruses are distributed in rodent populations world-widely even in geographical areas where hemorrhagic fever with renal syndrome (HFRS) has not been reported. Serologic diagnosis of infection, using hantaviral antigen, indicates that hantaviruses are wider distributed in wild rodents. This study was designed to intended the hantavirus infection among wild rodents captured in Kyebang mountain, Kangwon-do in Korea. A total of 216 wild rodents in 3 species were trapped in July and September in 1995. Serological evidence for hantaviruses infection were tested against five hantavirus antigens by indirect immunofluorescent antibody technique (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius (IFA). Among 100 Eothenomys regulus, 78 Apodemus peninsulae and 38 Apodemus agrarius; 12 C. regulus, 15 A. peninsulae and 6 A. agrarius were IF antibody positive against hantaviruses. This data suggest that Eothnomys regulus and Apodemus peninsulae would be a natural reservoir of hantaviruses.

Bowenoid papulosis (BP) is largely a disease of young, sexually active adults, which presents with pink or flesh colored macular or papular lesions in the anogenital area. It has been established that various human papilloma virus (HPV) types are the causative agents of BP and of these, HPV-16, the oncogenic one, is the most common. The course of BP is variable, ranging from spontaneous regression to persistent of lesions to a transformation into squamous cell carcinoma. We report a case of Bowenoid papulosis in a 29-year-old, sexually active female whose anogenital area was covered with innumerable papular lesions extended to the lower extremities.

PURPOSE: To compare the usefulness of double-dose contrast-enhanced CT (DDCE-CT) and conventional contrast-enhanced CT (CCE-CT) in the detection of metastatic brain lesions. MATERIALS AND METHODS: Sixteen patients with brain metastases were evaluated with both CCE-CT and thinslice DDCE-CT. For CCE-CT, an initial injection of 100 ml contrast medium was given, and DDCE-CT with both 10-mm and 5-mm thickness was performed after the addition of an extra 100 ml of contrast medium. The numbers of metastatic lesions detected by CCE-CT and by DDCE-CT were compared, as were the findings of contrast-enhanced MRI (CE-MRI) and thin-slice DDCE-CT in seven patients who underwent both these procedures. RESULTS: Fourteen metastatic brain lesions were detected by CCE-CT, 22 by 10-mm-thickness DDCE-CT, and 36 by 5-mm thickness DDCE-CT. Thus, almost 2.6 times more lesions were detected by thin-slice DDCE-CT than by CCE-CT. Metastatic lesions were detected by 10-mm-thickness DDCE-CT in 16 patients and by CCECT in seven; in five, edema only was detected, while in four there were no detectable metastases. CCE-CT detected four lesions of less than 5 mm in diameter, while 10-mm-thickness DDCE-CT and 5-mm-thickness DDCE-CT detected seven and 18 lesions, respectively. Eleven lesions were detected by thin-slice DDCE-CT and 17 by CE-MRI in the seven patients who underwent both CE-MRI and DDCE-CT. The lesions detected only by CE-MRI were less than 5 mm in diameter and were discovered in the cerebellum or inferior temporal lobe. CONCLUSION: Thin-slice DDCE-CT was superior to CCE-CT in detecting metastatic brain lesions.

Tuberculosis and lymphoma, these 2 diseases can present with lyphadenopathy in anywhere of the body. Therefor differentiation of tuberculosis from lymphoma is often difficult. CT scans of 17 patients with tuberculosis and 23 patients with lymphoma were retrospectively reviewed to evaluate the efficacy of CT scans in differentating adenopathy between tuberculosis and lymphoma, All the patients underwent abdominal CT scans with contrast enhancement before treatment. The size, internal architecture, distribution of lymph nodes, and associated findings on CT scans were analyzed. As compared with lymphoma, tuberculous lymphadenopathy showed 1) female preponderance (65%), 2) predilection for portocaval lymph nodes (47%), 3) internal low attenuation in lymph nodes (82%), 4) cold abscess formation (24%). Characteristics of lymphoma on CT scans included 1) male prepondrance (78%), 2) conglomeration of lymph nodes (39%), 3) homogenous internal lymph node structure (83%). These results suggest that evaluation of the characteristics of lymphadenopathy on CT scans is helpful for differentiating between tuberculosis and lymphoma.

Kimura's disease is an uncommon, chronic inflammatory disorder of unknown etiology that is seen in an endemic form in the Orient. It usually presents as a mass in the subcutaneous tissue of the head and neck region or the major salivary glands, and is often associated with a regional lymphadenopathy. The patients have peripheral blood eosinophilia and elevated IgE levels but are otherwise usually healthy. We encountered the case of a 33-year-old man who had a soft tissue mass in his left distal arm which was diagnosed as being Kimura's disease.
