Meningiomas extended to the scalp without any bony changes are rare. A 79-year-old man presented with a large subcutaneous mass in the midline parieto-occipital region and progressive right hemiparesis. ⋯ Histopathologic examination of both intracranial and extracranial tumors demonstrated the same atypical meningioma (World Health Organization grade II). The possible route of extracranial extension of the tumor may be the sizable parietal foramen.

The diagnosis and management for juvenile psammomatoid ossifying fibroma (JPOF) of the skull base are challenging, and clinical data are limited. ⋯ The present series of skull base JPOFs showed that radical surgery combined with skull base reconstruction contributed to overall good prognosis. Further studies are needed to evaluate the long-term outcomes and to characterize its pathologic characteristics.

Case Reports
Rare hereditary Klippel-Feil syndrome and Arnold-chiani Malformation caused by cervical spondylotic myelopathy.
A rare case of familial genetic disorder Klippel-Feil syndrome and Arnold-Chiari malformation caused by cervical spondylotic myelopathy was reported here. ⋯ Although the disease genetic characteristics have been studied, operation is necessary when it leads to abnormal neurologic symptoms and the surgery of surgery can have a beneficial outcome.

The release of the placode and reconstruction of the myelomeningocele, preserving the maximum neural tissue is a challenge for the neurosurgeon. Vascular fluorescence with indocyanine green and/or fluorescein allows observation of the microvascularization of the spinal cord and adequately identifies viable tissue.

Cranioplasty is a relatively simple and straightforward intervention; however, it is associated with a high incidence of postoperative seizures. Postcranioplasty seizures, especially early seizures, are common and associated with poor outcomes and longer hospital stays. Protocols for preventing and managing early seizures have not been well established. ⋯ Cranioplasty is associated with a high incidence of postoperative seizures. Our management protocol for postcranioplasty seizures includes seizure prophylaxis and advanced use of AEDs, which can reduce the occurrence of early seizures.
