Review Case Reports
Total resection of inferiorly located sacral chordoma with posterior only approach: case report and review of the literature.
Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1- 4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. ⋯ Using the retrorectal fat tissue as a cleavage line in the posterior approach guides the neurosurgeon to resect the tumor totally and reduce the hemorrhage in sacral chordomas. In this case report, we tried to discuss the advantages of using of retrorectal fat tissue as a cleavage line in sacral chordomas under the literature.

Case Reports
Is spontaneous spinal epidural hematoma in elderly patients an emergency surgical case?
Spontaneous spinal epidural hematoma (SSEH) is a rare condition requiring urgent diagnosis and treatment. Patients with SSEH typically present with acute onset of severe back pain and rapidly develop signs of compression of the spinal cord. The authors present a case with spontaneous resolution of SSEH which is extremely rare. ⋯ The neurological deficits showed complete recovery on the 25th day of the clinical course. SSEH is rare and immediate surgical decompression is suggested. Rapid neurological deterioration followed by early and progressive neurological recovery, confirmed by radiological resolution of the lesion, may indicate nonoperative treatment.

Case Reports
Chronic ossified epidural hematoma after ventriculoperitoneal shunt insertion: a case report.
Chronic calcified/ossified epidural hematoma is an uncommon complication of ventricular shunt surgery. There are only 4 cases related to valve-regulated shunt operations in the literature. It may be seen especially in young patients with chronic hydrocephalus, probably due to craniocerebral disproportion. ⋯ She was admitted with a complaint of severe headache after three years and a bifrontal calcified/ossified epidural hematoma was seen. The calcifying hematoma was removed and the patient's headache resolved. Although the use of high or medium pressure valves, valves with an antisiphon device, adjustable pressure valves or flow control valves have been recommended to prevent this complication in previous reports, it was seen that our case had been treated with a medium pressure flow control valve.

We examined the clinical progress of low back pain and radicular pain during the premenstrual period in patients with lumbar disc protrusion and discussed the probable effective physiopathological mechanisms and laboratory results reported in the literature. ⋯ All the criteria that we chose from the modified "Low Back Outcome Scale of Greenough and Fraser" to assess the pain showed a significant difference between the premenstrual period and the normal period in our patients. This difference should be considered in the treatment strategies in the clinical setting. Patients should be re-evaluated for surgical decisions after the premenstrual period if possible.

The microanatomy of the abducens nerve (AN) is important for clinical reasons and surgical approaches as it is located in the petroclival region. The incidence of branching and duplication of the abducens nerve are unknown and mechanisms relating to paralysis of the nerve in indirect conditions are yet to be clarified. ⋯ Branching of the AN was present in a significant number of specimens; the branching pattern at the cavernous segment may be called "pseudobranching". The AN is at risk for paresis in indirect conditions because of its angles and fixations on its course.
