Bilateral and symmetric C1-C2 dumbbell ganglioneuromas associated with neurofibromatosis type 1: A case report.

Background: Ganglioneuroma (GN) is a rare and benign tumor that originates from autonomic nervous system ganglion cells. The most frequently involved sites are the posterior mediastinum, the abdominal cavity, and the retroperitoneal space. It rarely occurs in the cervical area, compressing the spinal cord.

Erythromycin pretreatment induces tolerance against focal cerebral ischemia through up-regulation of nNOS but not down-regulation of HIF-1α in rats.

The purpose of this study was to determine whether the antibiotic erythromycin induces tolerance against focal cerebral ischemia, and the possible underlying mechanism including the involvement of neuronal nitric oxide synthase (nNOS) and hypoxia-inducible factor-1α (HIF-1α). In rat focal cerebral ischemia models, we found that erythromycin preconditioning could significantly decrease the cerebral infarct volume and brain edema. Meanwhile, the neurological deficits from day 4 through 7 after surgery were also remarkably decreased after erythromycin preconditioning.

Microsurgical management of bronchogenic cysts in the thalamus: an illustrative case and literature review.

Intracranial bronchogenic cysts are extremely rare. This is the first reported case of a bronchogenic cyst arising from the thalamus. Complete microsurgical resection was undertaken.

Microsurgical management of giant malignant peripheral nerve sheath tumor of the scalp: two case reports and a literature review.

Malignant peripheral nerve sheath tumors of the scalp are rare lesions of the nervous system. Only 14 cases have been reported to date. The field of neurosurgery has struggled with diagnosing and treating these tumors.
