ABSTRACT
BACKGROUND: Tumors with cysts often correlate with gliomas, metastatic tumors, or hemangioblastomas, which require differentiation. METHODS: Thirty-eight cases of cyst associated-meningioma based on preoperative radiologic studies and histologic confirmations were reviewed from November 1998 to July 2017. RESULTS: A total of 395 cases of meningioma were observed in the 20 years, and surgical treatment of intracranial meningioma was performed in 120 cases. Thirty-eight (9.6%) cases of cyst associated meningiomas were analyzed. Nauta type I was the most common type of cyst (39.5%) and the most frequent histopathological subtype was meningothelial type (36.8%). CONCLUSION: Statistically there were no significant associations between meningioma histopathological type and associated cysts; however, the rate of World Health Organization grade II was higher in cyst associated meningiomas than in unrelated meningiomas. This correlation was weak, in accordance with the meningioma grade.

BACKGROUND: Bile acids have anti-cancer properties in a certain types of cancers. We determined anticancer activity and its underlying molecular mechanism of ursodeoxycholic acid (UDCA) in human DU145 prostate cancer cells. METHODS: Cell viability was measured with an MTT assay. UDCA-induced apoptosis was determined with flow cytometric analysis. The expression levels of apoptosis-related signaling proteins were examined with Western blotting. RESULTS: UDCA treatment significantly inhibited cell growth of DU145 in a dose-dependent manner. It induced cellular shrinkage and cytoplasmic blebs and accumulated the cells with sub-G1 DNA contents. Moreover, UDCA activated caspase 8, suggesting that UDCA-induced apoptosis is associated with extrinsic pathway. Consistent to this finding, UDCA increased the expressions of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptor, death receptor 4 (DR4) and death receptor 5 (DR5), and TRAIL augmented the UDCA-induced cell death in DU145 cells. In addition, UDCA also increased the expressions of Bax and cytochrome c and decreased the expression of Bcl-xL in DU145 cells. This finding suggests that UDCA-induced apoptosis may be involved in intrinsic pathway. CONCLUSIONS: UDCA induces apoptosis via extrinsic pathway as well as intrinsic pathway in DU145 prostate cancer cells. UDCA may be a promising anti-cancer agent against prostate cancer.

PURPOSE: The purpose of this study is to investigate differences in organ-specific cancer incidence according to the region and population size in Korea. MATERIALS AND METHODS: We reviewed the data of the cancer registration program of Gyeongnam Regional Cancer Center between 2008 and 2011. Age-standardized rates of cancer incidence were analyzed according to population size of the region and administrative zone. RESULTS: Incidence of thyroid cancer has been increasing rapidly in both urban and rural areas. However, the thyroid cancer incidence was much lower in rural areas than in urban areas and megalopolis such as Seoul. Gastric cancer was relatively more common in rural areas, in megalopolis near the sea (Ulsan, Busan, and Incheon), and other southern provinces (Chungcheongnam-do, Gyeongsangbuk-do, and Gyeongsangnam-do). A detailed analysis in Gyeongsangnam-do revealed that rural areas have relatively low incidence of thyroid and colorectal cancer, and relatively high incidence of gastric and lung cancer compared to urban areas. CONCLUSION: This study suggests that there are some differences in cancer incidence by population size. Thyroid and colorectal cancer incidence was increasing, and gastric and lung cancer was slightly decreasing in urban areas, whereas gastric and lung cancer incidence still remains high in rural areas.

OBJECTIVE: The risk factors for surgical site infections (SSIs) after cranioplasty following decompressive craniectomy remain unclear. The goal of this study was to analyze the risk factors related to developing SSIs after cranioplasty and to suggest valuable predictors. METHODS: A retrospective review was conducted of patients who underwent cranioplasty following decompressive craniectomy at our institution from January 2011 to December 2014, a total of 78 patients who underwent 78 cranioplasties. Univariate and multivariate logistic regression analyses were carried out to determine possible risk factors related to developing SSIs. We analyzed both patient-specific and surgery-specific factors. RESULTS: The overall rate of SSIs was 9.0% (7/78). SSIs after cranioplasty were significantly related to being female, having the primary etiology of traumatic brain injury (TBI) and having had a bilateral cranioplasty in the univariate analysis. Multivariate logistic regression analysis showed that being female [odds ratio (OR) 5.98, p=0.000] and having had a bilateral cranioplasty (OR 4.00, p=0.001) significantly increased the risk of SSIs. CONCLUSION: Based on our data, cranioplasty following decompressive craniectomy is associated with a high incidence of SSI. Being female, having a primary etiology of TBI and having had a bilateral cranioplasty may be risk factors for surgical site infections after cranioplasty.

BACKGROUND: Cisplatin (cis-diaminedichloroplatinum, CDDP) is a widely used chemotherapeutic agent for the treatment of many cancers. However, initial resistance to CDDP is a serious problem in treating these cancers. Vitis coignetiae Pulliat (Meoru in Korea) have shown anti-nuclear factor kappa B and anti-epidermal growth factor receptor activities in cancer cells. METHODS: In this study, in order to seeking an approach to increase the anti-cancer effects of CDDP with natural products. Here, we investigated anthocyanins isolated from Vitis coignetiae Pulliat (anthocyanidins isolated from meoru, AIMs) can enhance anti-cancer effects of cisplatin (CDDP) in stomach cancer cells. The cell viability of SNU-1 and SNU-16 cells after treated with AIMs and CDDP were analyzed by MTT assay. The expressions of Akt and X-linked inhibitor of apoptosis protein (XIAP) proteins were examined by western blot in AIMs- and CDDP-treated cells. RESULTS: We found that AIMs enhanced anticancer effects of CDDP, which activity was additive but not synergistic. AIMs suppressed Akt activity of the cancer cells activated by CDDP. AIMs also suppressed in XIAP an anti-apoptotic protein. CONCLUSIONS: This study suggests that the anthocyanins isolated from fruits of Vitis coignetiae Pulliat enhanced anti-cancer effects of CDDP by inhibiting Akt activity activated by CDDP.

OBJECTIVE: The presence of a cerebral aneurysm remnant after surgical clipping is associated with a risk of regrowth or rupture. For these recurred aneurysms, coil embolization can be considered as a treatment option. We retrospectively reviewed cases of ruptured or regrown aneurysms after clipping treated by endovascular coil embolization. MATERIALS AND METHODS: We conducted a retrospective review of patients with ruptured or recurred aneurysm after clipping, who underwent coil embolization between January 1995 and December 2013. We evaluated clinical information and the outcomes of these cases. RESULTS: Eight patients were treated by endovascular coil embolization after surgical clipping. Six aneurysms were located in the anterior communicating artery, one in the posterior communicating artery, and one in the middle cerebral artery bifurcation. All patients were initially treated by surgical clipping because of a ruptured aneurysm. Aneurysm recurrence at the initial clipping site was detected in all cases. The median interval from initial to second presentation was 42 months. In four patients, aneurysms were detected before rupture and the four remaining patients presented with recurrent subarachnoid hemorrhage. All patients were treated by coil embolization and showed successful occlusion of aneurysms without complications. CONCLUSION: Endovascular coil embolization can be a safe and successful treatment option for recurred aneurysms after clipping.

Gout is a common metabolic disease in which monosodium urate crystals called tophi develop. Spinal involvement in gout resulting in neural compression is unusual. We describe a case of a 64-year-old man with a history of gouty arthritis of the knee. The patient presented with thoracic myelopathy and radiculopathy. Imaging of the spine revealed an extradural mass lesion with bony erosion of the thoracic spine. A decompressive operation was performed, and a chalky white material was found. Histopathological examination confirmed a gouty tophus. The symptoms of spinal gout vary and its radiological features are not sufficiently specific to provide a definite diagnosis. Therefore, in patients with a history of gouty arthritis who present with neural compressive symptoms of the spine, spinal gout should be strongly suspected.

OBJECTIVE: The conscious patients with a small amount of acute subdural hematoma had no neurological deterioration are managed conservatively. Most of them are resolved spontaneously in several weeks without surgery. In our experience, however, some progressed to chronic stage requiring surgical treatment in a few days, unlike chronic subdural hematoma derived from acute hematoma following several weeks or months after head trauma. We aimed to analyse this phenomenon and associated the risk factor comparing with the chronic subdural hematomas. METHODS: Retrospective analysis of 175 alert patients with unilateral acute subdural hematoma identified among 661 patients diagnosed the acute subdural hematoma from October 2009 to September 2012 was performed. Univariate and multivariate analyses were performed to describe the relationships between progression to chronic stage requiring surgery from small amount of acute subdural hematoma and clinical characteristics and radiologic features. RESULTS: Eighteen patients (10.3%) showed neurological deterioration due to progression to chronic stage of acute subdural hematoma and underwent a surgical treatment. The mean time interval between the head trauma and development of neurological symptoms was 12.7 days. Univariate and multivariate analyses found that depth of hematoma and degree of brain swelling were a risk factor for progression to chronic stage requiring surgery from the acute subdural hematoma. CONCLUSION: In spite of the conscious patients with acute subdural hematoma not requiring surgical decompression, the more amount of hematoma and the severer brain swelling, there is higher probability of neurological deterioration caused by the progression to chronic stage in a few days.

OBJECTIVE: The purpose of this study was to investigate the patterns and the risk factors of newly developed vertebral compression fractures (VCFs) after percutaneous vertebroplasty (PVP). METHODS: We performed a retrospective review of the 244 patients treated with PVP from September 2006 to February 2011. Among these patients, we selected 49 patients with newly developed VCFs following PVP as the new VCFs group, and the remaining 195 patients as the no VCFs group. The new VCFs group was further divided into 2 groups : an adjacent fractures group and a nonadjacent fractures group. The following data were collected from the groups : age, gender, body weight/height, body mass index (BMI), bone mineral density (BMD) score of the spine and femur, level of initial fracture, restoration rate of anterior/middle vertebral height, and intradiscal cement leakage, volume of polymethylmethacrylate (PMMA). RESULTS: Age, gender, mean body height/weight, mean BMI and volume of PMMA of each of the group are not statistically significantly associated with fractures. In comparison between the new VCFs group and the no VCFs group, lower BMD, intradiscal cement leakage and anterior vertebral height restoration were the significant predictive factors of the fracture. In addition, new VCFs occurrence at the adjacent spines was statistically significant, when the initial fracture levels were confined to the thoracolumbar junction, among the subgroups of new VCFs. CONCLUSION: Lower spinal BMD, the greater anterior vertebral height restoration rate and intradiscal cement leakage were confirmed as risk factors for newly formed VCFs after PVP.

BACKGROUND AND OBJECTIVES: The aim of this study was to compare endoscopic endonasal transsphenoidal hypophysectomy (EETSA) with microscopic transseptal transsphenoidal hypophysectomy (MTTSA) in terms of clinical results during an acceleration of learning curve. SUBJECTS AND METHOD: A retrospective chart review was performed of the first 14 cases of EETSA and previous 14 cases of MTTSA. Resection results, endocrinologic outcomes, complication rates, operating time, and duration of hospital stay were investigated. A non-parametric analysis was performed to determine the significance of differences between groups. RESULTS: EETSA was performed, achieving gross total removal, based on postoperative MRI, for 12 of the 14 patients (86%) and hormonal remission for 4 of the 5 patients (80%); on the other hand, MTTSA was performed, achieving gross total removal for 9 of the 14 patients (64%) and hormonal remission for 1 of the 5 patients (20%). We found better resection results in patients who underwent EETSA than in those who did MTTSA with respect to tumors extending into suprasellar area (p<0.05). Visual improvement was achieved in all the cases with visual defect (n=5) after EETSA, whereas 4 of 6 cases (66%) were improved after MTTSA. Significant differences in complication rates, operating time and hospital stay could not be determined. All cases with CSF leakage in EETSA were successfully managed by using the nasoseptal flap. CONCLUSION: EETSA provided better resection results than MTTSA did, especially in cases extending into the suprasellar area, showing good hormonal cure and visual improvement rates. Two approaches were comparable with respect to complications during the learning curve.

The expanded endonasal approach (EEA) to the ventral skull base provides endoscopic access from the frontal sinus to the second cervical vertebra. Potential advantages of the EEA include not only improved cosmesis but more importantly, the potential for reduced neurovascular manipulation. EEA is based on the principle of extracapsular dissection with full visualization of important neurovascular structures. There are significant risks of neural and vascular injury associated with EEA, and the reconstruction of dural defects is challenging. Experienced teams including rhinologists and neurosurgeons are needed for successful implementation of EEA. The surgical team must have adequate endoscopic skills to achieve hemostasis and address vascular emergencies. Advantages of having a skilled second surgeon to provide endoscopic visualization include dynamic adjustments of the endoscope to ensure the best view and avoid contact interference of instruments, second surgical opinions in complex anatomical areas, and maintenance of endoscopic views in cases of crisis such as vascular injury. Complications of the EEA such as neurovascular injury, cerebrospinal fluid leaks and infection are the same as those of open approaches. With the advent of the nasoseptal flap, problematic cases involving huge bony defects subsequent to the resection of skull base tumors have been greatly resolved.

OBJECTIVE: The purpose of this retrospective study was to evaluate the efficacy and safety of atlantoaxial stabilization using a new entry point for C2 pedicle screw fixation. METHODS: Data were collected from 44 patients undergoing posterior C1 lateral mass screw and C2 screw fixation. The 20 cases were approached by the Harms entry point, 21 by the inferolateral point, and three by pars screw. The new inferolateral entry point of the C2 pedicle was located about 3-5 mm medial to the lateral border of the C2 lateral mass and 5-7 mm superior to the inferior border of the C2-3 facet joint. The screw was inserted at an angle 30degrees to 45degrees toward the midline in the transverse plane and 40degrees to 50degrees cephalad in the sagittal plane. Patients received followed-up with clinical examinations, radiographs and/or CT scans. RESULTS: There were 28 males and 16 females. No neurological deterioration or vertebral artery injuries were observed. Five cases showed malpositioned screws (2.84%), with four of the screws showing cortical breaches of the transverse foramen. There were no clinical consequences for these five patients. One screw in the C1 lateral mass had a medial cortical breach. None of the screws were malpositioned in patients treated using the new entry point. There was a significant relationship between two group (p=0.036). CONCLUSION: Posterior C1-2 screw fixation can be performed safely using the new inferolateral entry point for C2 pedicle screw fixation for the treatment of high cervical lesions.

PURPOSE: To compare the dose distributions between three-dimensional (3D) and four-dimensional (4D) radiation treatment plans calculated by Ray-tracing or the Monte Carlo algorithm, and to highlight the difference of dose calculation between two algorithms for lung heterogeneity correction in lung cancers. MATERIALS AND METHODS: Prospectively gated 4D CTs in seven patients were obtained with a Brilliance CT64-Channel scanner along with a respiratory bellows gating device. After 4D treatment planning with the Ray Tracing algorithm in Multiplan 3.5.1, a CyberKnife stereotactic radiotherapy planning system, 3D Ray Tracing, 3D and 4D Monte Carlo dose calculations were performed under the same beam conditions (same number, directions, monitor units of beams). The 3D plan was performed in a primary CT image setting corresponding to middle phase expiration (50%). Relative dose coverage, D95 of gross tumor volume and planning target volume, maximum doses of tumor, and the spinal cord were compared for each plan, taking into consideration the tumor location. RESULTS: According to the Monte Carlo calculations, mean tumor volume coverage of the 4D plans was 4.4% higher than the 3D plans when tumors were located in the lower lobes of the lung, but were 4.6% lower when tumors were located in the upper lobes of the lung. Similarly, the D95 of 4D plans was 4.8% higher than 3D plans when tumors were located in the lower lobes of lung, but was 1.7% lower when tumors were located in the upper lobes of lung. This tendency was also observed at the maximum dose of the spinal cord. Lastly, a 30% reduction in the PTV volume coverage was observed for the Monte Carlo calculation compared with the Ray-tracing calculation. CONCLUSION: 3D and 4D robotic radiotherapy treatment plans for lung cancers were compared according to a dosimetric viewpoint for a tumor and the spinal cord. The difference of tumor dose distributions between 3D and 4D treatment plans was only significant when large tumor movement and deformation was suspected. Therefore, 4D treatment planning is only necessary for large tumor motion and deformation. However, a Monte Carlo calculation is always necessary, independent of tumor motion in the lung.

The majority of acute post-traumatic subdural hematomas (ASDH) require urgent surgical evacuation. Spontaneous resolution of ASDH has been reported in some cases. We report here on a case of a patient with a large amount of ASDH that was rapidly reduced. A 61-yr-old man was found unconscious following a high speed motor vehicle accident. On initial examination, his Glasgow Coma Score scale was 4/15. His pupils were fully dilated and non-reactive to bright light. Brain computed tomography (CT) showed a massive right-sided ASDH. The decision was made to treat him conservatively because of his poor clinical condition. Another brain CT approximately 14 hr after the initial scan demonstrated a remarkable reduction of the previous ASDH and there was the new appearance of high density in the subdural space adjacent to the falx and the tentorium. Thirty days after his admission, brain CT revealed chronic SDH and the patient underwent surgery. The patient is currently able to obey simple commands. In conclusion, spontaneous rapid resolution/reduction of ASDH may occur in some patients. The mechanisms are most likely the result of dilution by cerebrospinal fluid and the redistribution of hematoma especially in patients with brain atrophy.

Discal cysts are rare lesions that can cause radiating leg pain. Because they are very rare, their natural history and the details of the therapeutic guidelines for the treatment of these cysts are still unknown. A 30-year-old male patient presented to our institute with radiating pain in his left leg and mild back pain. Magnetic resonance imaging (MRI) revealed an intraspinal extradural cystic mass with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images at the L5-S1 level. The partial hemilaminectomy and cyst resection were performed. We report a patient with low back pain and radiating leg pain caused by a lumbar discal cyst and discuss the treatment of this cyst.

OBJECTIVE: The authors present their experiences with stereotactic multiplanar reformatted (MPR) computed tomography (CT)-guided catheter placement for thrombolysis of spontaneous intracerebral hematoma (sICH) and their clinical results. METHODS: In 23 patients with sICH, MPR CT-guided catheter placement was used to select the trajectory and target point of hematoma drainage. This group was comprised of 11 men and 12 women, and the mean age was 57.5 years (range, 31-79 years). The patients' initial Glasgow Coma Scale scores ranged from 7 to 15 with a median of 11. The volume of the hematoma ranged from 24 mL to 86 mL (mean 44.5 mL). A trajectory along the main axis of the hematoma was considered to be optimal for thrombolytic therapy. The trajectory was calculated from the point of entry through the target point of the hematoma using reformatted images. RESULTS: The hematoma catheter was left in place for a median duration of 48.9 hours (range 34 to 62 hours). In an average of two days, the average residual hematoma volume was 6.2 mL (range 1.4 mL to 10.2 mL) and was reduced by an average of 84.7% (range 71.6% to 96.3%). The residual hematoma at postoperative seven days was less than 5 mL in all patients. There was no treatment-related death during hospitalization. CONCLUSION: The present study indicates that stereotactic MPR CT-guided catheter placement for thrombolysis is an accurate and safe procedure. We suggest that this procedure for stereotactic removal of sICH should be considered for the optimization of the trajectory selection in the future.

OBJECTIVE: The purpose of the study was to determine the clinical effects of anterior radical debridement on a series of patients with spontaneous spinal infection. METHODS: We retrospectively analyzed the clinical characteristics of 32 patients who underwent surgical treatment from January 2000 to December 2005 in our department. The average follow-up Period was 33.4 months (range, 6 to 87 months). Thirty-two patients presented with the following : 23 cases with pyogenic spondylitis, eight with tuberculous spondylitis and one with fungal spondylitis. The indications for surgery were intractable pain, failure of medical management, neurological impairment with or without an associated abscess, vertebral destruction causing spinal instability and/or segmental kyphosis. RESULTS: The study included 15 (46.9%) males and 17 (53.1%) females ranging in age from 26 to 75 years (mean, 53.1 years). Diabetes mellitus (DM) and pulmonary Tbc were the most common predisposing factors for pyogenic spondylitis and tuberculous spondylitis. Staphylococcus aureus (13%) was the main organism isolated. The most prevalent location was the lumbar spine (75%). Changes in the pain score, Frankel's classification, and laboratory parameters demonstrated a significant clinical improvement in all patients. However, there were recurrent infections in two patients with tuberculous spondylitis and inappropriate debridement and intolerance of medication and noncompliance. Autologous rib, iliac bone and allograft (fibular) were performed in most patients. However, 10 patients were grafted using a titanium mesh cage after anterior radical debridement. There were no recurrent infections in the 10 cases using the mesh cage with radical debridement. CONCLUSION: The findings of this study indicate that surgery based on appropriate surgical indications is effective for the control of spinal infection and prevention of recurrence with anterior radical debridement, proper drug use and abscess drainage.

We report the successful removal of a retrobulbar foreign body using a transcranial approach in a 63-year-old patient with a penetrating injury to the left eye. Initial ocular examination revealed a corneoscleral laceration, hyphema, a traumatic cataract, and vitreous hemorrhage. Visual acuity consisted only of the perception of hand motion. Computed tomography demonstrated an orbital foreign body in the retrobulbar area. Emergency corneoscleral suturing, phacoemulsification of the cataract, and vitrectomy with posterior vitreous detachment were performed. Fifteen days after the emergency operation, we successfully removed the orbital foreign body using a transcranial approach, although the foreign body was very close to the optic nerve. On fundus examination 6 months later, a white, fibrous lesion was seen inferior to the optic disc, and the corrected visual acuity was 20/30. These positive results may be due to the complete vitrectomy at the correct time performed by a retina specialist and the minimal pressure on the eyeball while removing the foreign body, which resulted from the use of a transcranial approach.

We report a case of anaplastic ganglioglioma. A 45-yr-old woman was admitted with a 5-month history of headache and dizziness, both of which progressed slowly. Preoperative magnetic resonance imaging revealed a strong enhancing mass in the left frontal lobe extending to the cingulate gyrus. Adjuvant radiation therapy and chemotherapy were given after gross total resection of the tumor. Histological and immunohistochemical studies showed an anaplastic ganglioglioma. Gangliogliomas of the central nervous system are rather uncommon tumors, and anaplastic ones are extremely rare. The pertinent literature regarding gangliogliomas is reviewed.
