OBJECTIVE: In recent years, the neurosurgeon's role in managing cerebrovascular diseases (CVD) has becomes rapidly challenged and overlapped with other specialists. Furthermore, the patterns of CVD and patient recruitment have also changed. We conducted a retrospective study regarding the practical trends of CVD with reference to the management paradigms at our institute. METHOD: We reviewed all the available data, including the annual reports, the daily department records, the medical records and the radiographic films of the CVD patients who had been admitted to our Neurosurgery Department during the five years between Jan. 2004 and Dec. 2008. RESULTS: The total numbers of CVD operations showed a slight initial increase, but then they remained steady for the latter 3 years. The number of cases of non-angiomatous hemorrhage has been relatively steady, regardless of surgery. The total numbers of treated aneurysms increased, but the main body of this increment was attributed to the initiation of endovascular treatment and increased identification of unruptured vascular lesions. Vascular malformations were sustained with a small number of cases due to referring them to other institutes for radiosurgery, except for the cases that required urgent hemorrhagic evacuation. CONCLUSION: Hemorrhagic CVDs tended to decrease either due to increasing identification before rupture or shifting such patients into a large volume hospital. The increasing awareness of ischemic CVD, the early detection of unruptured aneurysms, and the separation of medical responsibilities from neurologists have all pushed neurosurgeons to make treatment plans in a more cooperative fashion, instead of a competitive way. Neurosurgeons should be furnished with several revolutionary surgical options to widen their scope of managing patients with CVD.

We report a case of linear arranged multiple cutaneous leiomyoma in a 45-year-old man. About 20 years ago, multiple normal skin colored firm papules developed on the left anterior chest and increased in number and size arranging in linear pattern. Some larger nodular lesions changed into brown in color and became painful after cold exposure. The lesions looked like keloid at first sight but the histopathologic finding showed typical leiomyoma in which the interlacing bundles of smooth muscle fibers with varying amount of collagen bundles intermingled.

Familial benign pemphigus is a skin disease with recurrent blistering lesions, mainly in the neck and intertriginous areas. The course of the disease is characterized by spontaneous exacerbations and remissions. The many remedies for this disorder include topical and systemic glucocorticosteroids, and antibacterial and antimycotic agents. However, these therapies usually do not prolong the remission periods. Surgical treatments, such as skin graft, have been more successful. Laser treatment has reported to be effective in recurrent familial benign chronic phemphigus. Here we report a case of familial benign chronic phemphigus that was treated with carbin dioxide laser.

OBJECTIVE: Transpedicular screw fixation has some disadvantages such as postoperative back pain through wide muscle dissection, long operative time, and cephalad adjacent segmental degeneration (ASD). The purposes of this study are investigation and comparison of radiological and clinical results between interspinous fusion device (IFD) and pedicle screw. METHODS: From Jan. 2008 to Aug. 2009, 40 patients underwent spinal fusion with IFD combined with posterior lumbar interbody fusion (PLIF). In same study period, 36 patients underwent spinal fusion with pedicle screw fixation as control group. Dynamic lateral radiographs, visual analogue scale (VAS), and Korean version of the Oswestry disability index (K-ODI) scores were evaluated in both groups. RESULTS: The lumbar spine diseases in the IFD group were as followings; spinal stenosis in 26, degenerative spondylolisthesis in 12, and intervertebral disc herniation in 2. The mean follow up period was 14.24 months (range; 12 to 22 months) in the IFD group and 18.3 months (range; 12 to 28 months) in pedicle screw group. The mean VAS scores was preoperatively 7.16+/-2.1 and 8.03+/-2.3 in the IFD and pedicle screw groups, respectively, and improved postoperatively to 1.3+/-2.9 and 1.2+/-3.2 in 1-year follow ups (p<0.05). The K-ODI was decreased significantly in an equal amount in both groups one year postoperatively (p<0.05). The statistics revealed a higher incidence of ASD in pedicle screw group than the IFD group (p=0.029). CONCLUSION: Posterior IFD has several advantages over the pedicle screw fixation in terms of skin incision, muscle dissection and short operative time and less intraoperative estimated blood loss. The IFD with PLIF may be a favorable technique to replace the pedicle screw fixation in selective case.

We present a case of acute subarachnoid hemorrhage in a 64-year-old male with sudden onset of left ophthalmoplegia. Cerebral angiography demonstrated a 10mm elongated aneurysmal sac which arose from the left internal carotid-anterior choroidal artery junction. The pterional approach was performed as an early surgery for aneurysm clipping. At operative field, the anterior choroidal artery aneurysm which directed posteromedially and compressed the origin of left oculomotor nerve was confirmed. And the blood blister like-aneurysm was also seen at the superolateral portion of the proximal bifurcation of the internal carotid-anterior choroidal artery. A large anterior choroidal artery aneurysm was clipped and the blood blister like-aneurysm was reinforced. No case report has been previously published describing a ruptured anterior choroidal artery aneurysm accomplished with third cranial nerve palsy. We reported a case of multiple aneurysms of anterior choroidal artery that caused ipsilateral oculomotor nerve palsy.

A 63-year-old man was presented with a tender, solitary nodule on the right shoulder. A biopsy specimen showed various sized irregular vascular lumens in the upper dermis. The vascular walls consisted of an endothelial cell layer and rim of one to three layers of glomus cell nests outside the endothelial cells. The cell nests consisted of round shaped epitheloid cells with relatively uniform round or oval shaped nuclei and pale cytoplasm. These tumor cells were strongly positive for vimentin, and alpha-smooth muscle actin. We report a case of a solitary glomus tumor(glomangioma) that showed the histological features of the multiple type of glomus tumor.

OBJECTIVE: Bilateral C1-2 transarticular screw fixation (TAF) with interspinous wiring has been the best treatment for atlantoaxial instability (AAI). However, several factors may disturb satisfactory placement of bilateral screws. This study evaluates the usefulness of unilateral TAF when bilateral TAF is not available. METHODS: Between January 2003 and December 2007, TAF was performed in 54 patients with AAI. Preoperative studies including cervical x-ray, three dimensional computed tomogram, CT angiogram, and magnetic resonance image were checked. The atlanto-dental interval (ADI) was measured in preoperative period, immediate postoperatively, and postoperative 1, 3 and 6 months. RESULTS: Unilateral TAF was performed in 27 patients (50%). The causes of unilateral TAF were anomalous course of vertebral artery in 20 patients (74%), severe degenerative arthritis in 3 (11%), fracture of C1 in 2, hemangioblastoma in one, and screw malposition in one. The mean ADI in unilateral group was measured as 2.63 mm in immediate postoperatively, 2.61 mm in 1 month, 2.64 mm in 3 months and 2.61 mm in 6 months postoperatively. The mean ADI of bilateral group was also measured as following; 2.76 mm in immediate postoperative, 2.71 mm in 1 month, 2.73 mm in 3 months, 2.73 mm in 6 months postoperatively. Comparison of ADI measurement showed no significant difference in both groups, and moreover fusion rate was 100% in bilateral and 96.3% in unilateral group (p=0.317). CONCLUSION: Even though bilateral TAF is best option for AAI in biomechanical perspectives, unilateral screw fixation also can be a useful alternative in otherwise dangerous or infeasible cases through bilateral screw placement.
