A 73-year-old female patient, who had been treated with antituberculous drugs for 4 months, was referred to our department because of generalized macules and papules present for 15 days. Clinical examination revealed polygonal, flat papules of erythematous to violaceous hue on the entire skin. Histopathologic findings were similar to those of lichen planus. In a provocation test with ethambutol, the skin lesions were aggravated and the new lesions developed. We considered this case to be a lichenoid drug eruption due to ethambutol. The skin lesions gradually cleared after ethambutol was eliminated from the patient's tuberculosis therapy.

Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum (SCC). However, the clinical implications of this lesion are unclear and are not always consistent with ischemic infarctions. We performed this study to clarify the clinical and radiological implications in patients with SCC lesions. Methods: We retrospectively reviewed consecutive patients with MRIreported SCC changes between 2009 and 2012. We analyzed clinical and radiological findings, etiologies, cognitive impairment, and clinical outcomes. Results: We found 30 patients (16 females; mean 50.5 years) who had SCC lesions on MRI. Confusion was the most common clinical finding in 50% of cases. Cerebral infarction was the most common etiology (50%). The most consistent SCC changes on MRI were low signal in T1WI, high signal on T2WI and FLAIR, and high signal on DWI. We classified SCC lesions into in situ SCC lesions (SCC only) and multiple (SCC plus) lesions for patients with multiple lesions. The clinical symptoms of SCC only lesions were relatively mild. Cognitive functions were evaluated by Mini Mental State Examination (MMSE) and clinical dementia rating (CDR) scale at the time of discharge and patients with SCC only lesions showed less impaired cognition compared with those with SCC plus lesions. Clinical outcomes were evaluated by the modified Rankin scale at 1 month and patients with SCC only lesions revealed good clinical outcomes compared with those with SCC plus lesions. Conclusions: MRI-reported SCC lesions may have heterogeneous etiologies and present with various symptoms. The clinical course and outcome are relatively good, particularly in small isolated and oval shaped SCC lesions.

Background & Objective: Hiccups is a disabling condition of lateral medullary infarction (LMI). Unlike other symptoms of LMI, the anatomical lesions of hiccups are not well known. Few studies have evaluated the relationship between the lesional location of LMI and hiccups. We performed this study to correlate hiccups and magnetic resonance imaging (MRI)-based lesional location in pure LMI. Methods: Between January 1997 and February 2013, we identified 24 patients with pure LMI who presented with hiccups in addition to typical lateral medullary syndrome. Sixty six pure LMI patients without hiccups were included as a control group. Clinical and radiologic findings were compared between the two groups. MRI-identified lesions were classified rostrocaudally as rostral, middle and caudal, and horizontally as typical, ventral, large, lateral and dorsal. Results: The pure LMI patients with hiccups had significantly more frequent aspiration pneumonia (P = 0.001) and longer hospital stay (P = 0.03). The patients with hiccups significantly more often had dorsal rather than ventral lesion at horizontal levels (P = 0.012). But, there were no rostro-caudal differences at vertical levels (P = 0.162). Conclusions: We suggest that pure LMI associated with hiccups often locates in the dorsal medulla at horizontal correlation. This MRI-based comparative study has advanced the understanding of the neural substrate for hiccups in LMI, and indicates that hiccups become predictable when specific lesional locations in the lateral medulla are considered.

BACKGROUND: Coronary arteriovenous(AV) fistula is a rare congenital disease, and seldom produce symptoms during childhood. However late complications can occur including congestive heart failure, myocardial ischemia, and bacterial endocarditis. Therefore surgical repair is recommended even if the patients are asymptomatic. In these days many investigators are interested in transcatheter embolization because of high procedural success rate without risks and morbidity associated with cardiac surgery. METHODS: Five patients(4 females and 1 male) of coronary AV fistula were treated with transcatheter coil embolization. All had symptom of chest pain. In coronary angiograms fistulous tracts were originated from left anterior descending artery(LAD) and drained to main pulmonary artery(MPA) in 4 cases. The other case had abnormal vessel from left circumflex artery(LCX) to bronchial artery. Transcatherter coil embolization were done with Judkins left guiding catheter, 018 inch Tracker or 3F Microferret catheter, and 018 inch coils. RESULTS: The fistula tracts were completely occluded in 3 cases after coil emboilzation. In 2 cases with multiple fistular vessels, major fistula were occluded, but minor vessels remained. There were no procedure related complications. CONCLUSION: Transcatheter coil embolization may be an effective treatment modality in coronary AV fistula with excellent result and minimal complications.

Dermoid tumors of tbe corneal limbus are failYly common congenital lesions. They are noted -at birth and may grow slowly in size and encroach upon the pupillary area occupying a site partly over the cornea and partly over the sclera. The tumors are yellowish, elevated and variable in size. Histologically the tumor consists of fibrofatty tissue covered by epidermoid epithelium and are invaded by ectodermal derivatives such as hair follicle, sebaceous and sweat glands. Trauma, irritation and puberty may hasten their growth. About 30% of patients with. corneal dermoid exhibit other congenital anomalies of ocular tissue, face, teeth, jaw, ear, spine, skull, and so on. Recently two cases of limbal dermoids were seen in our clinic. Histologically hair follicles and sebaceous glands are shown in one specimen, and cartHage and sebaceous glands in the other specimen.
