Isolated angiitis of the central nervous system is a rare clinicopathologic entity characterized by vasculitis restricted to the vessels of central nervous system without other apparent systemic vasculitis. It manifests headache, higher cortical dysfunction. focal neurologic dysfunction and cranial nerve palsies. We experienced a case of isolated angiitis of the central nervous system in 6 year-old girl who was admitted to out unit because of headache, hemiparesis and altered consciousness. The laboratory test for blood, urine, and cerebrospinal fluid are all within normal ranges. There was no evidence of systemic vasculitis. The contrast enhanced brain CT scan showed low densities along the left cerebellar hemisphere and posterior aspect of temporal lobe without enhancement, and left lateral internal carotid angiogram showed poorly contrast filling along the territory of left posterior cerebral artery due to narrowing or ischemic changes of the vessels. Axial T2WI (TR/TE, 2190/80) of magnetic resonance imaging showed multiple scattered high signal intensities at left pons with cerebellar hemisphere and diffuse high signal intensity along the left occipital lobe with enlarged surrounding gyral patterns, and axial T1WI(TR/TE, 665/25) showed intense gyral pattern contrast enhancement along the left occipital lobe. Steroid was tried with apparent benefit. We report a case of isolated angiitis of central nervous system with review of literature.

This study was performed ta evaluate difference of colposcopic findings between carcinoma in situ and microinvasive carcinoma. From August l, 1988 through November 30,1989, the conixation was undertaken in 138 patients. We compeied colposcpic findings with hiatologic diagnoiis on 1656 seetions. Comparison between the microinvasive carcinorna and the carcinoma in situ groups showed a significant higher incidence of large exoeervtcal lesion size(>3/2 33.9% vs. 1.2%), circumscribved location around external cervical os.(75.0% vs, 51.2%), combined abnormal colposcopic findings(19.6/a vs. 3. 7%) and deep endocervical involvement( >lcm : 23,2% vs. 7. 3%). (P<0.01) Granular area was showed 11% incidence of the worst histologic diagnosis.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.
