Thoracic Paraspinal Castleman Disease in a Young Mexican American Male with Postcoital Hematuria.
Castleman disease (CD) is an uncommon disorder of deregulated lymphoproliferation with unicentric (UCD) and multicentric forms based on extent of nodal involvement. Gross resection with histopathologic analysis remains the gold standard for diagnosis of UCD and is curative in most cases. Symptomatic paraspinal UCD is a rare presentation with potentially dangerous complications, and its tendency to mimic more common spinal tumors presents a significant diagnostic challenge. ⋯ Compared with previous reports, our case of postcoital hematuria and radiculopathy accompanying a paraspinal thoracic mass in a young Mexican-American man is a unique presentation. Awareness and early consideration of UCD in the work-up of a paraspinal mass may spare affected patients adverse and dangerous sequelae, such as spinal cord compression and excessive intraoperative hemorrhage.

An osteoid osteoma (OO) is a benign bone neoplasm that typically occurs in the long bone diaphysis. We found only 8 cases of OOs of the skull base in the literature, and none of them were located in the clivus. ⋯ The transsphenoidal approach with the use of neuronavigation appears to be a good choice to achieve total removal of an OO of the upper part of the clivus in case of persistent pain and lack of sufficient effect by nonsteroidal antiinflammatory drugs.

Microcatheter entrapment during embolization of brain arteriovenous malformations (AVMs) represents a potentially harmful technical complication. Although several techniques have been reported for endovascular catheter retrieval from an Onyx cast, such methods have never been demonstrated with acrylic glues. We report a case of removal of a glued microcatheter from an N-butyl cyanoacrylate (NBCA) cast using a microsnare. ⋯ Although it is not recommended as routine practice, snaring a glued microcatheter is feasible and can be used in selected cases as a last resort if thromboembolic complications are feared.

Surgical treatment for primary brainstem hemorrhage to improve postoperative functional outcomes.
It remains controversial whether primary brainstem hemorrhage (PBH) should be managed conservatively or treated promptly by surgical evacuation of the hematoma. In the present study, we discuss 5 cases of PBH that were treated surgically and the ability of surgical management to improve postoperative functional outcomes. ⋯ Because of the good results with these 5 patients with PBH, this surgical strategy could be encouraged with exclusion criteria for early initiation of rehabilitation strategies. We hope to increase our number of patients to accumulate further evidence.

The Barrow Innovation Center comprises an educational program in medical innovation that enables residents to identify problems in patient care and rapidly develop and implement solutions to these problems. Residents involved in this program noted an elevated risk of iatrogenic spinal cord injury during posterior cervical and thoracic procedures. The objective of this study was to describe this complication, and a novel solution was developed through a new innovation training program. ⋯ This report demonstrates how programs like the Barrow Innovation Center can provide neurosurgery residents with a unique educational experience in medical device innovation and intellectual property development and can serve as an avenue of surgical quality improvement and problem solving.
