325 patients underwent emergency evacuation of traumatic intracranial hematomas over a 5-year period. Ten(3%) developed delayed contralateral epidural hematomas. These hematomas were not present on initial computed tomography(CT) scan, but repeat CT scan after craniectomy showed sizable hemorrhage. The authors analyzed 10 cases with delayed post-traumatic contralateral epidural hematoma according to their etiology, hematoma types on computerized tomography, initial Glasgow Coma Scale(GCS) & follow up Glasgow Outcome Scale(GOS). 1) Delayed development of post-traumatic contralateral epidural hematoma after evacuation of initial hematoma occurred in 10 of the 325 head injured patients, an incidence rate of 3%. 2) The important factors affecting patients outcome were the initial GCS & the time interval after surgery. 3) Eight patients were found to have a skull fracture at the site of delayed epidural hematoma formation(80%). 4) The results of delayed contralateral epidural hematoma was 50% good, 50% bad and had a mortality rate of 30%.

OBJECTIVE: The aim of this study is to implement a critical pathway (CP) for patients undergoing lumbar laminectomy or microdiscectomy and describe the results before and after the CP in terms of length of hospital stay and cost. METHODS: From March 2008 to February 2009, 61 patients underwent lumbar laminectomy or microdiscectomy due to stenosis or one- or two-level disc herniation in our department and were included in the prepathway group. After development and implementation of the CP in March 2009, 58 patients were applicable for the CP, and these were classified as the postpathway group. RESULTS: The CP, which established a 6-day hospital stay (5 bed-days), was fulfilled by 42 patients (72.4%) in the postpathway group. The mean length of stay was 5.4 days in the postpathway group compared to 6.9 days in the prepathway group, demonstrating a 20% reduction, which was a statistically significant difference (p< or =0.000). There was a statistically significant reduction in charges for bed and nursing care (p=0.002). CONCLUSION: Implementation of a CP for lumbar laminectomy or microdiscectomy produced significant decreases in length of hospitalization and charges for bed and nursing care. We believe that this CP reduces the unnecessary use of hospital resources without increasing risk of adverse events.

Aneurysmal bone cysts (ABCs) are benign, non-neoplastic, expansile lesions. We present a case of a male patient aged 46 presented with 4-month history of left hip and low back pain and left hip swelling. Lumbosacral magnetic resonance imaging (MRI) and computed tomography (CT) demonstrated a large multi-loculated hemorrhagic lumbosacral and retroperitoneal mass with spinal dysraphism and tethered cord. Curettage and Biopsy were performed with partially resected cystic wall which was histological confirmed with aneurismal bone cyst. Large cystic mass of the vertebrae, sacrum, and pelvic bone must be considered with ABCs.

Superficial siderosis of the central nervous system(SSCNS) is a rare disease characterized by hemosiderin deposition on the surface of the central nervous system. We report a case of SSCNS originating from the thoracic spine, presenting with neurological deficits including, sensorineuronal hearing loss, ataxia, and corticospinal and dorsal column tract signs. The patient underwent dural repair with an artificial dural patch. Clinical findings were elicited by neurological examination, imaging studies, and intraoperative findings, and these were addressed through literature review.

A rare case of solitary diffuse large B-cell lymphoma arising from the lumbar spinal nerve root is reported. A 37-year-old man presented with a 3-month history of progressive numbness and paraparesis in both legs. The initial diagnosis was benign primary intradural extramedullary tumor including schwannoma and meningioma. Histopathological examination revealed diffuse large B-cell lymphoma. While a well-defined T1 isointense mass is common in primary spinal schwannoma, the present case was atypical and had a yellowish neural component. The pathogenesis and radiological findings of spinal diffuse large B-cell lymphoma are discussed and related literature is reviewed.
