Peritumoral edema induced by radiosurgery after the treatment of intracranial meningioma has been reported and its mechanism remains unclear. A 65-year-old woman presented with a history of intermittent dizziness. A CT scan and MRI of the brain revealed an extra-axial space-occupying lesion in the left frontal region. ⋯ Six months after SRS, this patient experienced deteriorated consciousness and general weakness. Peritumoral edema in the right temporal region was noted. We report these two patients, discuss possible causes and review the relevant literature.

The present study aimed to investigate the neuroprotective efficacy of dexmedetomidine in a rat experimental spinal cord injury model. The rats (n=40) were equally divided into four groups: G1, G2, G3, and G4. Rats in the G1 group underwent a laminectomy only. ⋯ The neuronal cell count in G1 was significantly higher than in G2 and G3 (p=0.0001; p=0.007). G4 had higher cell counts compared to G2 and G3 (p=0.0001; p=0.05). These findings indicated that dexmedetomidine might have neuroprotective effects in spinal cord injury.

A spectrum of surgical techniques has been used in the management of chronic subdural hematomas. Single burr hole and double burr hole drainage are among the commonest techniques. ⋯ Thus, the number of burr holes does not affect the post-operative recurrence rate of chronic subdural hematomas. Both techniques are equally effective treatments.

We report a 51-year-old man with an unusual intradural suprasellar chondroid chordoma. He presented with headache and diminution of vision in both eyes. MRI demonstrated the suprasellar tumor as an isointense mass with heterogeneous enhancement after intravenous administration of contrast agent. ⋯ Based on the histological characteristics of the tumor, which was composed of typical chordoma cells and islands of chondroid elements, we diagnosed a chondroid chordoma. We believe this is the first report of an entirely intradural chondroid chordoma on the suprasellar region. Clinical, radiological, and pathological features of the tumor are described.

Intracranial marginal zone B-cell lymphoma presenting as a dural-based mass is rare. A 45-year-old woman who had generalized tonic-clonic seizures and speech disturbance for 6 months was referred to our hospital. Radiology suggested a subdural hematoma (SDH). ⋯ Histopathological evaluation is necessary for diagnosis. MRI cannot reliably differentiate between SDH and some dural lesions that present as diffuse infiltration. Therefore, these differential diagnoses should be considered.
