OBJECTIVE: The purpose of this study is to evaluate the findings of magnetic resonance(MR) perfusion study and relation with the prognosis in patients of head trauma. METHODS: Forty-two consecutive patients with head trauma were evaluated and the findings of brain computed tomography(CT) and MR image were compared with MR perfusion study. We classified perfusion MR findings into 5 categories and correlated with the prognosis. RESULTS: In all 42 patients with head trauma, 38 cases(90.5%) showed new lesions of abnormal perfusion pattern in MR perfusion study compared to CT and conventional MR image. Causes of the trauma were motor vehicle accident(73.8%) falling(16.7%), and blows to the head(7.1%) in order of frequency. The cumulative prevalent sites of focal abnormalities were frontal lobe in 11 cases(39.3%), basal ganglia and thalamus 9 cases(32.1%), temporal lobe 3 cases(10.7%) and parietal lobe 3 cases(10.7%) and occipital lobe 1 case(3.6%) and cerebellum 1 case(3.6%). The pattern of abnormalities in MR perfusion study were focal type in 18 cases(42.8%), diffuse type 18 cases(42.8%), mixed type 4 cases(9.5%). MR perfusion findings showed statistically significant correlation with initial Glasgow Coma Scale score and Glasgow Outcome Scale score(p<0.05). CONCLUSION: The patterns of perfusion MR abnormality show significant correlation with the prognosis. Further study is mandatory to define the meaning of perfusion defect area and clinical significance.

Coincidental Arteriovenous malformation with pituitary tumor is very rare. Only two cases previously have been published in the world literature. A 63-year-old man was suffered from sudden loss of vision, vomiting and gait disturbance. Initial magnetic resonance image and cerebral angiography revealed a mass contained hemorrhage on pituitary fossa and arteriovenous malformation on the left frontal lobe. The tumor removed partially via transsphenoidal approach, and then embolization was performed for the arteriovenous malformation. Histological diagnosis of the mass was pituitary adenoma.

We analyzed parasitic diseases diagnosed by tissue biopsy specimens at KyungHee Medical Center (KMC) from 1984 to 2005. The total number of parasite infection cases was 150 (0.07%) out of the total 211,859 biopsy specimens submitted for histopathological examinations. They consisted of 62 cysticercosis, 23 sparganosis, 16 paragonimiasis, 15 amebiasis, 11 anisakiasis, 11 clonorchiasis, 3 ascariasis, 2 scabies, 2 enterobiasis, 2 trichuriasis, 1 leishmaniasis, 1 taeniasis, and 1 thelaziasis. Out of 62 cysticercosis cases, 55 were detected in subcutaneous tissues or the central nerve system. Eighteen out of 23 sparganosis cases were involved in muscular and subcutaneous tissues. In most anisakiasis cases, the involved organ was the stomach. The lung and the pleura were the most common site of paragonimiasis. The incidence of parasitic diseases during the first 5 years (1984-1988) was the highest of all observed periods. After 1989, similar incidences were shown throughout the period. Whereas cysticercosis was diagnosed in 34 cases during 1984-1988, no case has been diagnosed since 2000. In the case of sparganosis, the chronological incidence was almost uniform throughout the period 1984-2005. Paragonimiasis showed a similar tendency to cysticercosis. In gender and age distribution of parasitic diseases, men showed higher incidence rates than females, and the age groups of the 40s or older indicated higher infection frequencies than other age groups. Therefore, these results are a significant report to appear the tendency of human parasitic disease diagnosed by tissue biopsy in association with parasitosis at KMC in Seoul.
