We report a case of Hunter's syndrome in an 8-year-old boy, who presented with ivory-white colored papules and ridges on the left chest area, which were regarded as pathognomonic cutaneous markers for Hunter's syndrome. He also showed growth retardation, dear corneas, hepatosplenomegaly and fair intellect. The histopathological findings of papular lesions revealed loosely arranged collagen fibers with massive mutinous material which stained positively with alcian blue at both pH 2.0 and 0.5. On quantitation of glycosaminoglycans by hexuronic add assay in 24-hour urine, excessive excretion of creatinine was noted. To the best of our knowledge, this is the first case in Korea.

Kimura's disease is a rare benign disease characterized by subcutaneous or dermal tumors occurring predominantly on the head and the neck. It usually occurs in young adults without constitutional symptoms, except for peripheral blood eosinophilia. The histopathologic features of the tumor are characterized by dense lymphoid aggregates containing a prominent germinal center and by the proliferation of endothelial cells associated with varying degrees of lymphocytic, histiocytic, and eosinophilic infiltration. We report a case of Kimura's disease without peripheral blood eosinophilia in a 24-year-old male who had had a painless and slowly growing tumor-like swelling on his right groin for one year. The mass was excised, and the specimen was confirmed as Kimura's disease. After surgical excision, the lesion recurred, so 30 mg of oral prednisone was given daily for one month and then decreased gradually for another one month. Now, the lesion is completely healed.

PURPOSE: MR is the most useful imaging method in evaluating the anatomic changes of the optic chiasm (OC). The purpose of this study is to investigate the relationship between the OC displacement and visual manifestations. MATERIALS AND METHODS: We retrospectively reviewed 44 patients who showed displacement of OC on brain MR. The pattern of OC displacement was classified into 3 groups according to following criteria: group A included the patients with OC displacement only due to empty sella;group B represented the patients with OC displacement by a lesion and the border between the lesion and OC was distinct;and group C was the patients with OC displacement by a lesion and had a indistinct border or thinning of the OC. RESULTS: Visual symptoms and signs were noted in 12 patients and the most common sign was bitemporal hemianopsia. In group A(7 patients), the visual symptoms and signs were seen in only one patient(14%), in whom contracted visual fields persisted since previous pituitary apoplexy had developed. In group B(30 patients), the visual symptoms and signs were seen in 4 patients(13%) who had tumorous conditions except one case of cysticercosis. In group C(7 patients), the visual symptoms and signs were seen in all patients (100%). CONCLUSION: The more OC is compressed, the more the prevalence of visual symptoms and signs increases. However, there was no correlation between the occurrence of visual symptoms and the presence of OC displacement only without compression.

Heterotopic pregnancy, simultaneous intrauterine and extrauterine pregnancy, is an extremely rare case. The incidence of heterotopic pregnancy was about 1 to 30,000 pregnancies, but it has increased after wider use of assisted reproductive technology. The rising incidence presents a serious problem as the diagnosis of this potentially fatal condition is often missed. Careful pelvic examination combined with serial beta-hCG determinations, and transvaginal sonography to evaluate the adnexal region are necessary prerequisites for early diagnosis. We report a case of heterotopic pregnancy following in vitro fertilization and embryo transfer(IVF-ET) with a brief review of literature.

PURPOSE: To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluated in the healthy population. MATERIALS AND METHODS: Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricualr valve areas. RESULTS: Transient signal void was observed within the atrium near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called "physiologic atrioventricular valvular insufficiency". Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects didnot show any evidences of physiologic insufficiency. This physiologic condition does not extend more than lcm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. CONCLUSION: Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpfal in the study of the normal cardiac physiology.

Phakomatosis pigmentovascularis(PPV) was first described in 1947 as a distinctive association of vascular and pigmentary nevi by Ota et al. Hasegawa et al subclassified the disorder into eight types and type I a is characterized by the coexistence of nevus flammeus and nevus pigmentosus et verrucous, which is not associated with systemic organ involvement. PPV type I a is relatively rare and a case with multiple pyogenic granulomas developed in pregnancy, is not reported yet. We present a case of PPV type I a with multiple pyogenic granulomas developed in pregnancy within nevus flammeus in a 29-year-old female.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.

PURPOSE: To observe the hemodynamic change in brain tumors and peritumoral edemas after steroid treat-ment, and then nvestigate the clinical usefulness of perfusion MRI. MATERIALS AND METHODS: We acquired conventional and perfusion MR images in 15 patients with various in-tracranial tumors (4 glioblastoma multiformes, 4 meningiomas, 3 metastatic tumors, 1 anaplastic ependymo-ma, 1 anaplastic astrocytoma, 1 hemangioblastoma, and 1 pilocytic astrocytoma). For perfusion MR imaging, a 1.5T unit employing the gradient-echo EPI technique was used, and further perfusion MR images were ob-tained 2-10 days after intravenous steroid therapy. After processing of the raw data, regional cerebral blood volume (rCBV) maps were reconstructed. The maps were visually evaluated by comparing relative perfusion in brain tumors and peritumoral edemas with that in contralateral white matter. Objective evaluations were performed by comparing the perfusion ratios of brain tumors and peritumoral edemas. RESULTS: Visual evaluations of rCBV maps, showed that in most brain tumors (67%, 10/15), perfusion was high before steroid treatment and showed in (80%, 12/15) decreased afferwards. Objective evaluation, showed that in all brain tumors, perfusion decreased. Visual evaluation of perfusion change in peritumoral edemas revealed change in only one case, but objective evaluation indicated that perfusion decreased signifi-cantly in all seven cases. CONCLUSIONS: rCBV maps acquired by perfusion MR imaging can provide hemodynamic information about brain tumors and peritumoral edemas. Such maps could prove helpful in the preoperative planning of brain tumor surgery and the monitoring of steroid effects during conservative treatment.
