In meningioma, correlation of brain invasion with prognosis and clinical variables remains controversial. ⋯ Brain invasion and its patterns are correlated to gender. In contrast to the current WHO classification, invasion was associated with recurrence only after gross total resection and not independent of further histopathologic criteria of atypia.

Pseudocapsular resection is a useful surgical technique for removing functioning pituitary adenomas; however, the significance of this procedure in nonfunctioning pituitary adenomas (NFPAs) had not been discussed in detail. We clarify the safety of pseudocapsular resection in NFPAs based on the incidence of surgical complications and evaluation of pituitary function. ⋯ Pseudocapsular resection in NFPAs does not increase the risk of surgical complications or aggravate postoperative pituitary function.

Acute complex C2 vertebral body fracture specifically does not involve the odontoid process or C2 pars interarticularis. External stabilization can be effective but may prolong healing and increase morbidity. Many traditional surgical techniques can achieve internal stabilization at the expense of normal cervical motion. We describe direct surgical C2 pedicle screw fixation as an option for managing acute complex C2 vertebral body fracture. ⋯ Direct pedicle screw fixation of acute complex C2 vertebral body fracture appeared to be safe and effective in our 3 patients. It may provide a more-efficient and less-morbid treatment than halo brace or cervical collar immobilization in some patients.

Pleomorphic adenoma is a benign neoplastic tumor of the salivary gland. Salivary gland tumors in the intracranial cavity are generally restricted to the pituitary gland and sellar region. To our knowledge, there has been only 1 previous case report of a primary central nervous system pleomorphic adenoma outside of the sellar region. In that case report of a posterior fossa pleomorphic adenoma, typical myxochondroid stroma was not identified on histology, and its pathogenesis was not explored. ⋯ This case study illustrates a classic primary central nervous system pleomorphic adenoma in an unusual intracranial site. Its pathogenesis is postulated to involve salivary gland heterotopia.
