To retrospectively review the clinicopathologic features and computed tomography (CT) and magnetic resonance imaging (MRI) findings of spinal solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) tumors. ⋯ Spinal SFT/HPC commonly appears as a well-defined solitary mass characterized by a black and white appearance that is marked with heterogeneous enhancement with or without bone destruction.

Comparative Study
Optic Canal Decompression: A Comparison Of Two Surgical Techniques.
The optic canal is a bony channel that connects the anterior cranial fossa and orbit and contains the optic nerve and ophthalmic artery. It can be affected by several pathologies, leading to compression of the nerve nearby or inside the canal, leading to visual impairment. The usual technique to decompress the canal is through a craniotomy, but recently endoscopic endonasal approaches (EEAs) have surfaced as an interesting alternative due to direct access to the canal without the need for manipulation of neurovascular structures. ⋯ The decision for an approach for optic canal decompression should be based on the site of the pathology and localization of canal involvement. Both techniques are equivalent in terms of proportion of nerve decompression.

Pure endoscopic resection has become the most popular surgical approach for pituitary adenoma. Intraoperative magnetic resonance imaging (iMRI) systems have been in use for endoscopic resection of pituitary adenomas. This study aimed to evaluate the effectiveness of iMRI and neuroimaging navigation techniques during endoscopic endonasal transsphenoidal surgery of pituitary adenomas. ⋯ The use of iMRI and neuronavigation not only leads to a higher rate of tumor resection but also helps in detecting and removing hematomas in the surgical area. Follow-up examinations of extent of residual tumor at 3 months postoperatively were consistent with intraoperative results. Residual tumor volume in the suprasellar region was usually less than that observed intraoperatively.

Case Reports
Metastatic Neuroendocrine Carcinoma of Unknown Origin arising in the Femoral Nerve Sheath.
Metastatic neuroendocrine carcinoma of unknown origin is a rare condition, usually presenting with lesions in the liver and/or lung. We present the first reported case of a metastatic neuroendocrine carcinoma of unknown origin arising in the femoral nerve sheath. ⋯ We recommend that there is a definite role for surgery in the management of solitary neuroendocrine carcinoma of unknown origin.

This study aimed to evaluate the association of different stenting procedures with the procedure-related complications in stent-assisted coiling (SAC) of ruptured wide-necked aneurysms. ⋯ Different stenting procedures were associated with thromboembolic but not hemorrhagic complications in SAC of ruptured wide-necked aneurysms.
