Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

Thanatophoric dysplasia is the most common lethal congenital chondrodysplasia with characteristic features of narrow thorax, short rib, severe platyspondyly, short bowed limbs and skull deformity, etc. It is not a hereditary disorder and there is usually no family history of dysplasia. We experienced a case of thanatophoric dysplasia at 38 weeks of gestation with antenatal sonographic and abdominal radiographic findings of small thorax, short bowed extremities with surrounding thickened soft tissues and marked platyspondyly. Soon atter delivery, the baby died and post-mortem radiographs showed the characteristic findings of thanatophoric dysplasia.

Male Breast cancer is an uncommon disease with an incidence of I per cent of all breast cancers. Male breast cancer usually appears as a small mass with well-defined contour which is eccentrically located in relation to the nipple on mammogram. We report a case of breast cancer in a 51-year-old man with mammographic appearance of large hyperdense mass with nipple inversion and axillary lymphadenopathy, gray-scale sonographic finding of homogeneous solid mass and mu Itiple tumor vessels with in the mass on color Doppler ultrasound.

Although some cases of benign positional vertigo are associated with a chronic ipsilateral sensorineural hearing loss, an association with simultaneous ipsilateral sudden deafness is rare. We report a 53-year old woman with sudden deaf-ness with simultaneous positional vertigo in the same ear characterized by benign paroxysmal positional vertigo of pos-terior semicircular canal type. After a modified Epley particle-repositioning maneuver, the patient's vertigo was resolved. Clinical and neuro-otologic evaluations suggested that the lesion responsible for this patient was probably located within inner ear rather than within the vestibulocochlear nerve.

BACKGROUND: The relationship between the anterior site of acute myocardial infarction(MI) and occurrence of stroke has become a recent subject of much debate in the relevant literature. The object of this study was to examine the incidence of ischemic stroke during the hospitalization after an acute MI and to identify predictors of MI-related stroke. METHOD: We performed retrospective analysis of 452 patients with acute MI admitted to department of Neurology or Cardiology from January 1990 to August 1997. Patients with a stroke during hospitalization after acute MI were recruited for this study. RESULT: Thirteen cases were recorded. Seventy-seven percent (10/13) of the strokes occurred within 4 days after onset of MI. Multivariate analysis identified the following as independent predictors of stroke : History of hypertension(OR. 2.6: CI, 1.1 to 5.9), previous stroke(OR, 22.3: CI, 5.9 to 84.9) and congestive heart failure (CHF)(OR, 15.4: CI, 2.2-108.6). Transthoracic echocardiography(TTE) was performed in 349/452(77%) during hospitalization. The incidence of left ventricular thrombosis(LVT) in patients with anterior MI who received thrombolytic and anticoagulant therapy was not significantly different from that in patients with anterior MI who didn't(2.6% vs 6.1%, p=0.265). Stroke developed in only one of these patients with LVT. Thrombolytic and anticoagulant therapy were more frequently used in patients without stroke compared with stroke.(p<0.05). CONCLUSION: The incidence of stroke after acute MI is 2.9% and more frequent within the 4 days after MI. History of hypertension, previous stroke and congestive heart failure (CHF) were the factors independently favoring the occurrence of stroke, but there is no relation between the occurrence of stroke and anterior site of MI. Although intravenous thrombolytics followed by full anticoagulation treatment appeared to provide protection against ischemic stroke, it has no effect in the incidence of left ventricular thrombi in this study.

This study was performed to evaluate the effects of acute withdrawal of antiepileptic drugs in epileptic patients during continuous BEG monitoring. One hundred sixty-five withdrawals in 134 patients who were candidates for epileptic surgery were included for this study. Clinical features and frequency of seizure were observed after drug withdrawal with daily monitoring of serum drug level. The phases after withdrawal of antiepileptics were divided into phase of therapeutic drug level, phase of falling drug level, and phase of subtherapeutic or undetectable(zero) drug level. There were significant increase in frequency of seizure and seizure of secondary generalization after acute withdrawal of antiepileptic drugs. Number of seizure during the period of drugs withdrawals was not correlated with onset age of epilepsy, duration of epilepsy, duration of medication, and number of administrated antiepiteptic drugs. The number of frequency of seizure before drug withdrawal was correlated with the number of frequency of withdrawal seizure. The number of seizure frequency after carbamazepine withdrawal was significantly higher during the phase of subtherapeutic or zero drug level, and not during phase of rapid falling antiepileptic drug level.

The brain MR images of 23 patients with angiographically proved moyamoya disease were reviewed to evaluate the capability of MR to demonstrate vascular and parenchymal abnormalities. All the MR images were obtained on a 2.0 T superconducting system and included T1-weighted sagittal and T2-weighted axial images without implementation of flow compensation (FC). The vascular abnormalities demonstrated on MR images were narrowing of the cavernous internal carotid artery (ICA) (73%), narrowing or occlusion of the supraclinoid ICA (87%) and proximal middle cerebral artery (MCA) (91%), and multiple collateral vessels in the basal ganglia and/or thalamus (96%). The parenchymal abnormalities included ischemic infarctions (74%), predominantly located in watershed areas, hemorrhagic infarctions (26%), intracerebral hematomas (13%), and intraventricular hemorrhage (13%). In conclusion, MR imaging was a useful diagnostic modality for detecting both vascular and parenchymal abnormalities associated with moyamoya disease. This may obviate the need for invasive angiography as far as the diagnosis is wanted at the non-quantitative level.
