BACKGROUND: Accessory axillary breast tissue is present in approximately 2% to 6% of women, but receives little attention in the surgical literature. Furthermore, a carcinoma, as well as other pathologic changes, can arise within accessory axillary breast tissue. METHODS: Between January 1990 and December 1997 at our clinic, 83 patients underwent surgical removal of accessory axillary breast tissue. All the patients were female, and the ages ranged from 14 to 57 years, with a median of 33.8. The clinical characteristics, indications, and techniques of surgical removal, pathologic findings, and postoperative results were analyzed. RESULTS: The major clinical manifestations were axillary mass (95.2%), pain and/or tenderness (41%), and cyclic change of size (21.7%). In most patients, these symptoms appeared first during puberty (25.3%) and pregnancy (43.4%). On examination, the mass was in the right axilla in 35 patients (42.2%), the left axilla in 19 patients (22.9%) and both axillae in 29 patients (34.9%), and 3 patients had rudimentary accessory nipples. Surgical removal was performed for cosmetic problems (61.5%), clinical symptoms (21.7%), and suspicion of pathologic lesions (9.6%). The excised breast tissue varied in size from 2.5 cm to 14 cm with a median of 6.2 cm. The pathological findings demonstrated ductal dilatation in 21 patients (25.3%), chronic inflammation in 4 patients (4.8%), fibrocystic changes in 3 patients (3.6%) and lactating adenosis in 2 patients (2.4%). Postoperative complications developed in 8 patients (8.3%), and seroma was the most common. In our study, none of the patients experienced recurrence of disease, and 96.4% of the patients enjoyed cosmetically satisfying outcomes. CONCLUSIONS: In conclusion, from our experience, the treatment of choice for accessory axillary breast tissue is surgical removal, which eliminates the clinical symptoms and the aesthetical deformity and provides tissue to rule out any pathologic changes including malignancy. For cosmetically satisfying outcomes, a scar hidden from sight and balanced shapes of both axillae should be kept in mind during the operation.

Communication between coronary arteries and cardiac chambers or large vessels is unusual type of congenital malformation. Aneurysmal formation of a coronary arteriovenous fistula is even rare. We report a case of 83-year-old women with giant aneurysm of the coronary arteriovenous fistula from the left anterior descending coronary artery treated by percutaneous deployment of embolization coil.

OBJECTIVES: The optimal management of patients with spontaneous intracerebral hemorrhage (ICH) remains controversial. The aim of this study was to evaluate technical results and clinical outcomes of frameless stereotactic aspiration and fibrinolysis using urokinase performed in a single center. MATERIALS AND METHODS: The subjects of this study were 62 consecutive patients with spontaneous ICH who were treated with frameless stereotactic aspiration and subsequent fibrinolysis using urokinase between February 2009 and June 2010 in our hospital. The surgical results, procedure-related complications, and clinical outcomes were evaluated. RESULTS: A total of 62 patients were enrolled in the study. The median age was 54 years (range, 32-86). The mean initial Glasgow coma scale score was 7.7 (range 5-11). The mean initial hemorrhage volume was 43 cm3 (range 30-70). Seven patients (11.2%) died of respiratory failure (four patients), postoperative edema (two patients), and heart disease (one patient). There were seven cases of procedure-related complications (11.2%), including malpositioning of catheters (two patients), pneumocephalus (one patient), and rebleeding (four patients, 6.4%). At the three-month follow-up, a good outcome (three-month Glasgow outcome scale > 3) was noted in 32 patients (51.6%). CONCLUSIONS: Frameless stereotactic aspiration and subsequent fibrinolytic thearpy using urokinase for spontaneous ICH is a simple and safe procedure with low mortality and rebleeding rate.

OBJECTIVE: The objective of this study is to evaluate the clinical and angiographic outcomes after primary balloon angioplasty in patients with symptomatic middle cerebral artery (MCA, M1 segment) stenosis refractory to medical therapy. MATERIALS AND METHODS: Eleven patients with intracranial stenosis were treated with primary balloon angioplasty. All patients had MCA stenosis with recurrent transient ischemic attack (TIA). The indication for balloon angioplasty was patients with significant MCA stenosis: 1) age older than 18 years with recurrent or progressive TIA or infarction despite optimal medical therapy, including anti-coagulation, dual anti-platelet, and anti-lipid medication; 2) previous ischemic events or asymptomatic severe stenosis (more than 50%) with poor collateral cerebral circulation, or diminished cerebral perfusion on single photon emission computed tomography before and after administration of the intravenous dosage of acetazolamide. RESULTS: The median age of patients was 53 years (range 44-79). The technical success rate was 100%. Mean pretreatment stenosis degree was 83.63 +/- 9.53% and 29.1 +/- 15.4% before and after angioplasty, respectively. Procedural-related complications occurred in four of 11 patients (36%), but none of the patients had permanent neurological deficit. All patients were available for an average follow-up period of 19.4 +/- 5.1 months. One patient had a stroke in the territory of angioplasty at two months after angioplasty. The stroke free survival rate at 30 days and 12 months was 100% and 91%, respectively. Restenosis over 50% was observed in three of 11 patients (27%); all were asymptomatic. CONCLUSION: Intracranial angioplasty for symptomatic MCA stenosis refractory to medical therapy can be a treatment option to reduce the risk of further TIA or stroke.

We report an unusual case of cerebral aneurysmal subarachnoid hemorrage (SAH) with Fabry's disease. A 42-year-old woman presented with aneurysmal SAH originated from a saccular aneurysm of the right posterior communicating artery. The patient was treated by an endovascular coil embolization of aneurysm. Postoperatively the patient recovered favorably without any neurological deficit. During her admission, the patient had a sign of proteinuria in urine analysis. The pathologic findings of kidney needle biopsy implied nephrosialidosis (mucolipidosis of lysosomal stroage disease), which is consistent with a Fabry's disease. It is uncommon that Fabry's disease is presented with aneurysmal SAH, especially in middle-aged patients, but could be a clinical concern. Further investigations are needed to reveal risk factors, vascular anatomy, and causative mechanisms of Fabry's disease with aneurysmal SAH.

We report a rare case of chondrosarcoma arising from the dorsum sellae as it mimicked sellar and suprasellar mass. A 36 year-old man visited our hospital for his decreasing visual acuity. Brain magnetic resonance(MR) image revealed round a sellar and suprasellar mass showing mottled enhancement with internal cystic material. The MR image favored the diagnosis of craniopharyngioma, most likely, while plain skull X-ray showed sellar floor erosion and widening, which favored pituitary adenoma. The patient underwent trans-sphenoidal approach less than a week of admission and evaluation because his visual acuity was at a risk of blindness. In the operation, sellar mass was totally removed but some of suprasellar mass was inevitably remained due to limited surgical field. The pathologic diagnosis was chondrosarcoma. Six months from the first operation, pterional approach was performed to remove the remaining suprasellar mass, which didn't come down to sellar area. Intraoperative findings confirmed that the mass was originated from dorsum sellae.

Granular cell tumors (GCTs) have been reported in various tissues, especially the skin and subcutaneous soft tissue of the head and neck. We report a 60-year-old man who presented with intermittent headache and dizziness for 3 months, but no other neurological symptoms. Magnetic resonance imaging (MRI) showed the presence of a mass in the pituitary stalk, and contrast-enhanced MRI showed nodular enhancement in this region. The lesion was completely excised microscopically via a frontotemporal (pterional) approach. On pathological examination, a final diagnosis of a typical GCT was made.

BACKGROUND: The aim of this study was to investigate the feasibility and efficacy of emergent carotid artery stenting (CAS) for occlusion or high-grade stenosis of the internal carotid artery (ICA) in patients with acute ischemic stroke. METHODS: From November 2004 to May 2007, 17 patients admitted to the hospital within 12 hours of symptom onset with occlusion or a high-grade stenosis of the proximal ICA underwent emergent CAS. We analyzed risk factors, imaging findings, functional outcome scales, and peri-procedural complication. The outcome was measured by the modified Rankin scale (mRS) 3 months later and classified into good (mRS score of 0 to 2) or poor (mRS score of 3 to 6). RESULTS: All patients were recanalized successfully. The median National Institutes of Health Stroke Scale (NIHSS) score was 12.6 (range 4 to 24) just before the emergent CAS, which decreased to 9.4 and 8.2 at 1 day and 7 days after the stenting. Three months later, 12 patients showed good outcome while three had poor outcome and two of them died. Two patients (11.8%) exhibited symptomatic hemorrhagic transformation following the emergent CAS. Smoking status, and initial and immediate post-procedural NIHSS scores were associated with the outcome. CONCLUSIONS: Emergent CAS is a feasible and effective method in acute treatment of selected stroke patients with steno-occlusion of the proximal ICA.
