PURPOSE: To determine the characteristics of benign breast calcifications on mammogram. MATERIALS AND METHODS: Benign breast calcifications on mammograms of 25 patients, which were confirmed by needle localization and excisional biopsy(15 cases), cytology(1 case), or follow-up study(9 cases), were retrospectively analysed according to size, shape, number, distribution, and density. RESULTS: The size of benign breast calcifications was uniform in 4 cases (16%), and variable in 21 cases (84%). The shape of calcifications was round or oval in 18 cases(72%), linear or branching pattern in 6 cases (24%), and irregular in 1 case(4%). The number of calcifications was 2-5 in 7 cases(28%), and over 6 in 12 cases(48%). The distribution of calcifications was focal in 13 cases(52%) and diffuse in 12 cases(48%). The density of calcification was homogenous in all 25 cases(100%). CONCLUSION: Analysis of number, shape, size, and distribution is helpful for the diagnosis of benign breast calcifications. However the homogenous density of the calcification is suggested to be the most helpful criterion for the diagnosis of benign breast calcifications.

PURPOSE: This study was undertaken to correlate the CT and histopathologic findings of abscess wall. MATERIALS AND METHODS: The CT findings of 12 patients with pathologically proven brain abscess were retrospectively analyzed with particular attention to the thickness, smoothness and uniformity of enhancing abscess wall, and the results were correlated with histopathologic findings. RESULTS: Two patients with acute cerebritis showed an isodense ring on non-contrast CT(NCCT), but a true capsule formation could not be identified at pathologic examination. Six other patients with isodense ring on NCCT consisted of early to late cerebritis(3 cases), late cerebritis to early capsule(1 case), early capsule(1 case), and late capsule(1 case). These 6 cases showed ring enhancement on contrast enhanced CT(CECT) and true capsule formation pathologically. There was no isodense ring on NCCT in the remaining four patients. They consisted of early to late cerebritis(2 cases), late cerebritis(1 case), and late cerebritis to early capsule formation(1 case). These also showed ring enhancement on CECT and true capsule formation pathologically. CONCLUSION: We found that it is difficult to predict the exact stage of brain abscess on preoperative CT findings. It is suggested that clinical findings and sequential dynamic CT may provide more detailed informations for evaluation of abscess staging.

McArdle's disease is a disorder of carbohydrate metabolism, which is inhented as an autosomal recessive or occasionally an autosomal dominant trait. Hallmark of clinical features is exercise intolerence, I.e. muscle pain following strenuous exercise. Electrophysiologically insertion of an EMG needle shows that there is no electrical activity, differentiating this contracture from a muscle cramp. Histological examination of muscle biopsy specimen shows increase in glycogen and the presence of subsarcolemrnal blebs. We report a 23-year-old, male patient who presented clinical, electrophysiological, and histological findings compatible with McArdle's disease.
