We experienced a case of simple pneumonediastinum showing the findings of pleural effusion. Frontal chest radiography showed not only pneumomediastinum but also diffuse haziness with sharp medial margin on left lower lung field, blunting of costophrenic angle, and indistinct contour of diaphragm simulating pleural effusion. CT scan confirmed that these findings arose from the displaced pleura and the associated compression atelectasis by loculated air on the anterior mediastinum.

PURPOSE: The purpose of this study was to evaluate the ultrasonographic (US) features of traumatic neuromas in breast cancer patients after mastectomy. METHODS: This study was performed with approval from our Institutional Review Board, and the requirement for informed consent was waived. Six traumatic neuromas in five patients were included in this study. The US findings of traumatic neuromas were evaluated retrospectively by two radiologists according to the Breast Imaging-Reporting and Data System (BI-RADS) lexicon. The final assessment was also recorded. RESULTS: On US, all six lesions presented as a mass within the pectoralis muscle layer (mean size, 4.8 mm; range, 3.9 to 5.5 mm). Of the six masses, four had an oval shape with a circumscribed margin, and two had an irregular shape and an indistinct margin. They were all hypoechoic. Two lesions showed a non-parallel orientation. On color Doppler examinations, two lesions showed internal vascularity. Strain elastography was performed for four neuromas, resulting in scores of 1 (n=1), 4 (n=2), and 5 (n=1). The final assessment categories were BI-RADS 3 (n=2), 4A (n=2), and 4B (n=2). CONCLUSION: On US, an oval shape, circumscribed margin, parallel orientation, and hypoechogenicity were the most frequent features of traumatic neuromas in breast cancer patients after mastectomy. Neuromas may show increased vascularity on color Doppler imaging and present as a hard mass on elastography.

Tibric acid is a new oral hypolipidemic agent with the chemical name of 2-chloro-5(3,5-dimethyl piperidinosulfonyl) benzoic acid. The results of tibric acid administration in 22 patients with primary hyperlipidemia were as follows. 1) Serum triglyceride level was significantly decreased in 84.6% of 22 cases with an average 43.9% decrease in serum triglyceride. 2) Serum cholesterol level was decreased in 59.1% of 22 cases with an average 15.8% decrease in serum cholesterol. The decrease in serum cholesterol level was not significant. 3) It seemed that there were significant falls in the serum triglyceride of the hyperlipoproteinemia type IV and IIb patietns and in the serum cholesterol of type IIa patients 4) The side effects of tibric acid were indigestion, loose stool and anorexia. There was no side effects in 63.6% of cases.

The results of alpha-acetyldigoxin(Dioxanin(R)) administration in 21 patients with congestive heart failure were as follows. Alpha-acetyldigoxin is a new oral preparation of cardiac glycoside derived from lanatosid C. 1. For rapid digitalization in 2-3 days, the initial dose was 1.2 to 2.6mg (average 1.96mg). For medium-fast digitalization in 4 days, the loading dose was 2.0 to 3.2mg (average 2.7mg). For slow digitalization 0.1 to 0.4mg was required for 5 to 6 days without loading dose. The maintenance dose was 0.1 to 0.4mg (average 0.33mg) daily. 2. The therapeutic effect of acetyldigoxin was excellent in 15 cases (71%), good in 4 cases (20%) and stationary in 2 cases (9%). 3. Side effects were observed in 2 cases with usual dosage regimen. One accidental case who took single dose of 4mg(20 tablests) developed supraventricular tachycardia with varying degree of atrioventricular block, ventricular bigeminy and premature beat but recovered completely after 6 days.

We deacribe herein a case of Darier-White disease occurring to a 50-year-old man who had a characteristic lesions limited to the sun exposed area and no skin lesion in the sun protected area for 40 years. The akin lesions recurred in summer time and aggravated after sun exposure and disappeared spontaneously in winter time. Histologic findings from the neck lesions revealed hyperkeratosis, parakeratosis, supirabasal lacunae, acantholytic cells, villi, corps ronds and grains.

OBJECTIVE: Self-expanding stents are increasingly used for the treatment of complex intracranial aneurysms. The purpose of this study was to evaluate the usefulness and safety of a self-expanding nitinol stent (Enterprise) in the treatment of wide-necked intracranial aneurysms. METHODS: This was a retrospective study of 39 patients with 40 wide-necked intracranial aneurysms who were enrolled in a single-center registry of patients treated with the Enterprise between June 2009 and December 2011. Thirty patients were asymptomatic, four had cerebrovascular accident sequelae, and five had suffered subarachnoid hemorrhage. One aneurysm had reopened after prior coil embolization, while 39 had not been treated. Clinical charts, procedural data, and angiographic results, including both immediate post-procedural angiograms and follow-up imaging, were reviewed. RESULTS: The mean neck size of the aneurysms was 5.58 mm (range 3-15.1 mm). Embolization was successful in all patients. There were five procedure-related events. There were no fatalities, but one procedure-related morbidity was noted. The immediate angiographic results included eight complete occlusions (20%), six remnant necks (15%), and 26 remnant sacs (65%). At angiographic follow-up (mean: 11.3 months), out of 18 of the aneurysms treated with stent-assisted coiling, there were 13 (72.2%) complete occlusions, four (22.2%) remnant necks, and one recanalization (5.6%). CONCLUSION: Stent-assisted coiling using the Enterprise is effective for the treatment of wide-necked intracranial aneurysms. Further angiographic and clinical follow-up investigation will be needed for evaluation of the long-term outcomes.

Milk of calcium located in the breast is typically a benign entity. However, carcinoma may incidentally arise adjacent to or even within milk of calcium. Consequently, the characteristics of all observed calcific particles should be carefully analyzed. In this study, we report a case of carcinoma presented as malignant microcalcifications mixed within milk of calcium in a breast.

Anterior ischemic optic neuropathy is due to acute ischemia of the anterior part of the optic nerve, whose main source of blood supply is from the posterior ciliary circulation, either by direct branches or through the peripapillary choroid, with minor and differing contributions from other sources. The clinical features are charaterized by sudden visual impairment, optic nerve related visual field defect and optic disc edema. For pathogenetic as well as therapeutic reasons, these patient can be subdivided into two major subgroups: a nonarteritic group, an arteritic group. The authors experienced a case of AION, which occurred in a young male, probably arteritic. So, the literature of the AION was briefly reviewed and the purpose of this review is to increase awareness of this not uncommon condition.
