Malignant MCA(middle cerebral artery) infarction is one of the leading cause of fatal stroke. It is usually caused by occlusion of the ipsilateral MCA or ICA(internal carotid artery). We report a 62-year-old man with posterior circulation stroke(distal basilar artery occlusion) which was later developed in malignant MCA infarction. MRI(magnetic resonance imaging) revealed high signal intensities in more than 2/3 of the right hemispheres and also in the bilateral thalamus, occipital cortices extending to the midbrain, pons and right SCA(superior cerebellar artery) territory of the cerebellum. Ipsilateral ICA and MCA of the infarcted hemisphere were not visible but ipsilateral PCA(posterior cerebral artery) seemed to be relatively prominent compared with the contralateral side in MR Angiography. From the pont of view of the initial pathologic brainstem sign and MR findings, we suggest that embolic occlusion of the distal basilar artery might be responsible for malignant right MCA infarction in this patient, from which the right PCA had dominantly supplied the most of the ipsilateral hemisphere.

PURPOSE: The goal of this study was to estimate development of secondary sex characters and genitalia including testicular volume, penile length and girth, and prevalence of varicocele. In addition, we evalua ted the relationship between testicular volume and presence of varicocele. MATERIALS AND METHODS: A cross sectional study was conducted on 893 school boys between the ages of 14 to 15 years, 3rd grade middle school in Chonju city during the period september to October, 1999. The testicular volume was measured in the upright posture using Prader's orchidometer and penile length and girth were estimated with a ruler. Varicocele was evaluated by dubin's method. RESULTS: The testis volume (mean+/-SD) was 10.20+/-2.6ml on right and 9.93+/-2.6 on left and penile length (mean+/-SD) was 10.9+/-1.6cm and penile girth (mean+/-SD) was 8.0+/-0.8cm. The prevalence of varicocele was 38.2% (342/893) in left side, 16%(146/893) in right side. The difference in testicular volume between right and left testis was statistically significant in students with unilateral varicocele than the students without varicocele (0.78+/-1.06ml v/s, 0.54+/-1.01ml, p=0.004). CONCLUSIONS: In this study, we obtained mean testicular volume, penile length and girth and higher incidence rate of varicocele on adolescent school age group in Chonju area. The difference in testicular varicocele. The reduction of the testicular volume with varicocele correlated with the severity of grade of varicocele need following up to disclose the effect of the varicocele on the testicular growth and fertility potential.
