The double pylorus-is a fistulous communication between the gastric antrum and duodenal bulb, usually extending from the lesser curvature of the stomach to the superior aspect of the duodenal bulb, and seperated by septum or bridge of normal mucosa. Although its incidence is rare, reports concerning double pylorus are increasing with the recent development of upper gastrointestinal endoscopy and more awareness of this abnormality. We recently experienced two cases of double pylorus; an aquired one in 72-year old male who had an another opening with healing ulcer at the superior aspect of the original pyloric channel, central erosion with clubbing and fusion of mucosal folds at the greater curvature of the lower body and a 3 x 4 cm sized ulcer at the lesser curvature of the lower body, and the other congenital one in 53-year old male who had an another opening at the superior aspect of the original pyloric channel with histologically intact muscularis mucosa in the pyloric septum with no evidence of chronic peptic ulcer scarring. We report here two cases of double pylorus, one-acquired, and the other-congenital, with a review of the literature.

PURPOSE: To characterize the MRI appearance of the peripherally located schwannoma as compared with pathologic findings. MATERIALS AND METHODS: 11 cases of 13 lesions of the schwannoma confirmed by pathology were analyzed, retrospectively. T11 T2 and Gadolinium-enhanced T1 weighted sagittal and axial images were obtained. The signal intensity, contour of lesion, and relationship with surrounding tissue were analyzed. All cases were correlated with MRI and pathologic findings. RESULTS: In 9 out of the 11 cases, schwannoma was connected to the main nerve trunk. Among them, tumors were located centrally in 6 cases and eccentrically in 3 cases. MR findings of schwannoma were iso signal intensity on T1WI(8 cases) with muscle intensity, high signal intensity on T2WI(all cases), strong heterogenous enhancement in all cases. 8 cases showing heterogenous appearance on T2WI, showed mixture of Antoni-A and B area and multifocal hemorrhage. Central low and peripheral high signal intensity on T2Wl(Target sign) was mainly high cellular component in the central portion and diffuse myxoid degeneration at the periphery, pathologically. Reversed target appea.rance(central high, peripheral low on T2WI) revealed central cystic degeneration with low cellular component and hemorrhage in the central portion, and high cellular component at the periphery. Linear band-like low signal intensity on T2WI, suggesting capsule of the schwannoma, was not the true capsule proven by pathology. Thin true capsule was not visualized on T2WI. CONCLUSION: MR appearance of schwannoma was non-specific. The signal intensity on T2 weighted MR imaging was determined by the presence of multifocal hemorrhage, focal cystic and myxoid degeneration, admixture of Antoni-A and B area.

PURPOSE: To evaluate the surgical result and complications of scleral fixation of foldable intraocular lenses. METHODS: We reviewed the medical records of 17 patients who had undergone scleral fixation of acrylic three-piece foldable intraocular lens. RESULTS: Uncorrected visual acuity were improved in all eyes with time. Postoperative best corrected visual acuity were better than preoperative best corrected visual acuity in 14 eyes from 1.18+/-0.84 to 0.26 +/-0.25 in logMAR visual acuity. Estimated refractive error were 0.01+/-0.34 diopter in spherical equivalent preoperatively and .0.59+/-1.00 diopter postoperatively (p=0.02, paired t-test). The corneal astigmatic changes (dK) of mild against-the-rule astigmatism decreased as time passed. There was no intraoperative bleeding. There were postoperative complications such as increased intraocular pressure in 2 eyes, corneal epithelial defect in 1 eye. CONCLUSIONS: In cases of scleral fixation, by using acrylic foldable intraocular lens through small incision, we were able to reduce corneal astigmatism and complications due to large incision and therefore, improve visual acuity instantly.

PURPOSE: Narcolepsy is a specific neurologic syndrome consisting of excessive daytime drowsiness, cataplexy, and the additional phenomena of sleep paralysis and intense dreamlike hallucinations at sleep-wake transitions. We are reporting a patient with narcolepsy whose repeated self-injury caused traumatic eyeball perforation. METHODS: A 26-year-old male with narcolepsy injured himself, which resulted in eyeball perforation in his both eyes. We diagnosed him as traumatic corneal laceration, traumatic cataract, and vitreous opacity due to lens material in vitreous in both eyes. RESULTS: After improvement of narcoleptic symptom and healing of corneal perforation, we performed cataract extraction and pars plana vitrectomy under local anesthesia. During operation, we found preretinal gliosis at superior portion of optic disc and subretinal hemorrhage in the right eye. We observed successful improvement in visual acuity through intraocular lens implantation.

The evidence of infarction within the territory of the posterior cerebral artery could be diagnosed clinically using follow-up CT scan in whilt it has been pathologically well proved entity when the tentorial herniation occurred particulary in cases of head trauma with intracranial hematoma, although its incidence was generally within 10%. Visual field defects in traumatic intracranial surface hematomas have been proposed as result and directly optic tract or visual cortex. Authors experienced the infarction of occipital and temporal lobe on CT scans and the homonymous hemianopsia in 3 cases of 20 epidural hematomas after CT was available. The case histories and CT findings of the infarction were detailed and discussed. It may be stressed that the careful examination and frequent follow-up CT scan are performed even in epidural hematoma.

In adults, it is known that the choroid is the most eyeball common site of metastasis. However, only a few cases have been reported. The authors have experienced a case of pulmonary squamous cell carcinoma metastasis in the Lt. choroid in a 57 year old Korean male patient. We report this case and a review of the literature.
