Congenital cystic adenomatoid malformation of the lung(CCAML) is a rare developmental anomaly characterized by an "adenomatoid" hyperplasia of terminal respiratory structures with formation of the cysts of varying sizes. CCAML is separated into three major types based on the gross and microscopic findings. We have analyzed 22 cases of CCAML, those consisted of 6 autopsy cases and 16 surgical specimens. Out of 22 cases, 5 cases were composed of large cysts(type I) and 9 cases had multiple small cysts(type II). Remaining one case revealed features of solid type(type III), and 7 cases were mixed form. There were 16 boys and 6 girls. All cases were below the age of 14 years. There was no clear-cut age difference between different types of CCAML. However, inflammation, fibrosis and pseudostratification of epithelium were often found in older age. All fetal autopsy cases of CCAML had hydrops fetalis and were associated with maternal hydramnios. One case of type III showed definite mucinogenic cells in the cysts unexpectedly, and one case of the mixed form(typeI+II+III) was found in a fetus of 22 weeks of gestational age. Above findings contradicted the classical description of the CCAML, and suggested that arbitrary classification into three types may not be the best way in understanding this condition.

Ascariasis is probably the most common helminthic infestation of man, but it seldom causes severe illness. Pathologic conditions of Ascaris may be caused by adult worms, eggs or larvae. We describe a case of Ascaris egg granulomas that were found incidentally on the surface of the liver in a 75-year-old woman who had undergone a segmentectomy for an intrahepatic stone. Grossly, there were several yellowish calcific nodules of 0.4 cm in diameter on the lateral surface of the left lobe of the liver. Microscopically, the lesions were located in the hepatic capsule and consisted of fibrocalific nodules with many eggs. The eggs were round to oval, thick-shelled and measured 50~75x30~50 um. Most of the morphologically preserved eggs were fertilized eggs, but they had smooth shells without external protein coats. This case is of interest for the unusual location of the lesion, the presence of eggs without mammillation, and the association with the intrahepatic stone.

Cerebral amyloid angiopathy (C.A.A) is characterized by the extracellular amyloid protein deposition in the vessel walls of the brain and meninges. It has been estimated to account for 5 to 10% of all primary, nontraumatic brain hemorrhage. We report two cases of C.A.A causing nontraumatic intracerebral hemorrhage in the frontal lobe. The first case was a 60-year-old female who was admitted for the left hemiplegia and dysarthralgia. Brain CT revealed right frontal lobe hemorrhage. The second case was a 72-year-old male who was admitted for amnesia and gait disturbance. Clinical impression was Alzheimer's disease. Brain MRI revealed multifocal small hemorrhage in the right frontal lobe. Microscopically, both cases showed dilated small arteries of superficial cortex and meninges with hyalinization. Some vessels showed microaneurysm and fibriniod necrosis. Congo-red stain also exhibited birefringence under polarized light. There was no evidence of Alzheimer's disease.

The nonprogressive unilateral intracranial arteriopathy known as transient (focal) cerebral arteriopathy is not a well-recognized arteriopathy among practitioners of Korea and Japan, although it cannot be easily differentiated from early moyamoya disease. This review summarizes the nomenclature, pathophysiology, diagnostic evaluation, clinico-radiological features, and management of nonprogressive (reversible or stable) unilateral arteriopathy based on the relevant literature and our own experiences. Nonprogressive unilateral arteriopathy should be strongly suspected in children presenting with basal ganglia infarction and arterial beading. The early identification of patients likely to have nonprogressive or progressive arteriopathy would ensure proper management and guide further research for secondary stroke prevention.

The Sturge Weber syndrome is an uncommon disorder characterized by port-wine nevus of the face with angiomatosis of the ipsilateral cerebral leptomeninges and extensive calcification in the underlying cerebral cortex. Associated with this syndrome are mental retardation, choroidal angioma, buphthalmus or glaucoma, seizure and hemiplegia. We studied a case of incomplete form of Sturage Weber syndrome in a 12 year-old boy, who had generalized seizure, a homonymous hemianopsia, intracranial calcification and leptomeningeal angiomatosis. There are no characteristic facial nevus, mental retardation, occular changes and hemiplegia.

Endometriosis is defined as the presence of endometrial tissue(gland and stroma) outside the uterus. The incidence of scar endometriosis is quite rare, and must differentiate with cellulitis and abscess. We have experienced one case of perineal endometriosis and one case of abdominal wall endometriosis at the site of postoperative wound scar. The possible pathogenesis of endometriosis and treatment were discussed.

The term "chordoid meningioma" means meningioma, which is pathologically similar to chordoma, and previously reported that rarely associated with microcytic anemia and/or dysgammaglobulinemia especially in pediatric population. We present a case of this rare variant, which comprises less than 0.5% of all meningiomas. A 33-yr-old man visited our hospital, complaining visual field defect worsening over 7 yr. Neurological examination showed left homonymous hemianopsia. The brain magnetic resonance imaging revealed well enhancing right temporo-occipital mass with cystic portion. Histopathologic findings of resected tumor were compatible with chordoid meningioma which included trabeculae of eosinophilic, vacuolated cells in a myxoid matrix with prominent lymphoplasmacellular infiltration. The neoplastic cells were positive for vimentin and epithelial membrane antigen and negative for glial fibrillary acidic protein and cytokeratin. This is an adult case of chordoid meningioma without anemia or dysgammaglobulinemia.

We report a rare case of cavernous hemangioma (CH) which developed in adjacent location to a preexisting CH after gamma knife radiosurgery (GKRS). A 36-year-old woman underwent GKRS for a CH in the left lentiform nucleus. Three-and-half years after radiosurgery, MRI revealed a new CH in the left caudate nucleus. Surgical excision of the new lesion was performed. The pathological examination confirmed the diagnosis of CH. In radiosurgery for CH, it should be noted that a new CH may develop, which is likely to result from the interaction between radiation and predisposing factors of the patient.

OBJECTIVE: The purpose of this study is to investigate the difference on regional volume in temporal lobe between Alzheimer's disease patients with psychosis (AD+P) and Alzheimer's disease patients without psychosis (AD-P). METHODS: Altogether, 24 AD+P and 25 AD-P matched age, gender, and clinical dementia rating sum of box (CDR-SOB) were include from a Memory impairment clinics of Pusan National University Hospital in Korea. AD+P were diagnosed according to Jeste and Finkel's proposed diagnostic criteria for psychosis of Alzheimer's disease. Grey matter volume of temporal lobe was measured with 3-tesla magnetic resonance imaging and freesufer analysis. Analysis of variance was used to investigate the association between temporal lobe and AD+P after controlling age, gender, education years, CDR-SOB and total intracranial volume. RESULTS: We found an association between AD+P and reduced grey matter volume in total temporal lobe as well as in specific temporal regions such as left middle temporal lobe, left inferior temporal lobe, both hippocampus and both fusiform. CONCLUSION: Our findings suggest that AD+P are associated with reduced grey matter volume of temporal lobe.

A 37-year-old woman was admitted to our hospital with altered mentality. The patient was diagnosed an internal carotid artery (ICA) dorsal wall aneurysm leading to acute subdural hemorrhage (SDH) without occurring subarachnoid hemorrhage and/or internal parenchymal hemorrhage. An aneurysmal neck clipping and hematoma evacuation were performed at once. A pure SDH by ruptured aneurysm is unusual, but it is important to consider it if a SDH patient has no other medical history.
