Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

Nonpalpable breast abnormalities which require excision and biopsy usually require marker localization. Many of these abnormalities are visible on ultrasound and this imaging technique can be used to guide fine needle aspiration and the placement of a wire marker prior to surgical excision. A non-invasive technique which does not require placement of a wire marker would offer significant advantages, being more pleasant for the patient and less demanding on resources. We attempted to localize 36 nonpalpable breast masses with non-invasive ultrasound marker technique at the department of general surgery, Soon Chun Hyang University Hospital, between January 1994 and February 1995. Cases clearly visible on ultrasound, whether on mammography(15 patients) or not(17 patients), underwent non-invasive ultrasound localization. In all cases the abnormality was easily identified and removed during surgery. The surgical biopsies contained fibroadenoma(19 cases), fibrocystic disease(12 cases), epithelial hyperplasia(1 case), intraductal papilloma(1 case), parasitic disease(1 case) and infiltrating ductal carcinoma(2 cases). The average age was 43 years old.. This non-invasive technique is a simple and accurate method for localizing small ultrasonically visible nonpalpable breast abnormalities, especially in younger female patient with dense breast, though further trials and studies will be attempted.

Tuberous sclerosis is a rare multisystem syndrome characterized by hamartomatous tumors of the brain, skin, viscera, and eye. The diagnostic triad for this disease, proposed by Vogt, included epilepsy, mental retardation, and adenoma sebaceum. In eyes, retinal hamartomas and optic nerve phacoma are observed over 50% and hypopigmented areas of peripheral retina and iris are often found. We introduce an 18-year old girl with adenoma sebaceum of the face, history of epilepsy and insignificant mental retardation status. She also had a retinal hamartoma in her right eye, optic nerve phacoma in her left eye, shagreen patch on lumbosacral area, angiomyolipoma of both kidneys, periventricular subependymal nodules and calcified cortical nodule of occipital lobe of brain.

PURPOSE: To evaluate MRI findings of malignant ovarian tumors. MATERIALS AND METHODS: MRI findings were retrospectively reviewed in 25 patients with surgically confirmed 30 malignant ovarian tumors(common epithelial tumor;23, sex cord stromal tumor;2, endodermal sinus tumor ; 1, metastatic tumor ;4). The findings evaluated were the lesion size, solid and/or cystic component, wall thickness, septal thickness, necrosis, invasion of adjacent organ, ascites, and adenopathy. RESULTS: MRI findings of the malignant ovarian tumors were as follow:Size of lesion was 5-35cm(mean 14cm) ;solid component was present in 80%(24/30);wall thickness was more than 3ram in 90%(27/30);septal thickness was more than 3ram in 70%(21/30);tumor necrosis was present in 40%(12/30%) ;invasion of adjacent organ was present in 76%(19/25);ascites was present in 56%(14/25);lymphadenopathy was present in 24% (6/25). MRI findings of absence of solid component(6/6), even wall and septal thickness(7/7, 19/19) were found only in epithelial tumors. Uneven septal thickness more than 3mm(7/11) was a predominant MRI findings of non-epithelial tumors. Well-defined cystic lesion within solid component was seen in Krukenberg tumors. CONCLUSION: Evaluation of the lesion size, internal architecture, invasion of adjacent organ, ascites, and lymphadenopathy in MRI would enable diagnosis of malignant ovarian tumors and could lead to possible differential diagnosis of epithelial tumors from non-epithelial tumors.

Spinal meningiomas located purely in the extradural space are rare, and they may easily be confused with malignant neoplasm. We report an unusual case of a purely extradural spinal meningioma mimcking metestatic neoplasm. A 38-year-old woman had neck pain and left side weakness. MRI scan revealed extradural spinal mass. Preoperative and intraoperative diagnosis was metastatic carcinoma, but permanent diagnosis was extradural meningioma.

Congenital dermal sinuses result from a failure of separation of the cutaneous epithelial ectoderm from the neuroepithelial ectoderm along the dorsum of the embroy during the first month of intra-uterine life. These sinus tracts can occur at any level of the cerebro-spinal axis, but are located predominantly in the occipital and lumbosacral regions and occasional cases involving the cervical and thoracic regions. The dermal sinus tract is lined by stratified squamous epithelium and extends from the surface through the deeper tissues into the cranial or spinal cavity, usually ending on the dura or within the dura in conjunction with a terminal epidermoid or dermoid cyst. An intra-medullary epidermoid or dermoid with a dermal sinus is an unusual association. We have been able to find a previously reported coincidence of these malformations although there are many definitive papers on these uncommon entities. We are experienced in one case who are 14 months old boy with a intra-medullary dermoid cyst associated with a congenital dermal sinus at the T4 level, and reviewed related reports.

A 36-year-old female amateur cyclist developed mononeuropathy of the deep branch of the ulnar nerve due to nerve compression adjacent to the ulnar tunnel (type II Guyon’s canal syndrome) caused by prolonged bicycle riding.The patient’s signs and symptoms persisted even after refraining from cycling for 4 weeks; thus, she underwent decompression of the deep branch of the ulnar nerve in the palm and wrist. Three months postoperation, she recovered nearly full power and function of her left hand.

Polycythemia vera is one type of myeloproliferative disorder which occurs due to the clonal proliferation of hematopoietic stem cell related to the production of leukocyte and megakaryocyte which produces a little less than erythrocyte. Polycythemia vera has a peak incidence in the sixth decade of life with males affected slightly more frequently than females. Vasquez first described polycythemia vera as an autonomous erythrocytosis in 1892, and a further description, delineation of the disease process and a complete course outline were made in 1899, 1903 and 1938, respectively. Symptoms include pruritus, tinnitus, vertigo, gastrointestinal (GI) pain, and bleeding gums. Hyperuricemia and hyperuricosuria are present in about 40% of these patients. Complications are hemorrhage, thrombosis, post-polycythemic myeloid metaplasia, and leukemic transformation. In case of surgery, complications such as hemorrahge and thrombosis are highly likable to happen. We report a case of preoperative and postoperative of a 63-year-old male, who was diagnosed as oral cavity cancer in the mouth floor, with known history of hypertension and polycythemia vera. We considered that conservative management would be an advisable treatment for patients with uncontrolled systemic disease
