The clinical management of spinal hemangiomas and osteolytic metastases involving the upper cervical spine (C1-C3) is challenging. Symptoms vary from simple vertebral pain to progressive neurological deficits. Surgery and radiotherapy have been the treatment options for years. Surgery, however, can result in complications, such as hemorrhage, and may be counter-indicated when the treatment goal is primarily palliative due to multiple metastases, an unfavorable prognosis and/or a poor performance state. On the other hand, radiotherapy carries the risk of inducing secondary sarcomas or producing radionecrosis. Percutaneous vertebroplasty (PVP) was recently introduced as an alternative for treating patients in whom surgery and radiotherapy are counter-indicated. As of yet, there are few PVP case reports. ⋯ The safety and efficacy of CT-guided PVP using a translateral approach via the space between the carotid sheath and vertebral artery were demonstrated in patients with hemangioma or metastasis in the upper cervical spine. CT-guided PVP via a translateral approach should become a treatment option for such patients.

Review Case Reports
Percutaneous osteoplasty for the treatment of a painful osteochondral lesion of the talus: a case report and literature review.
An osteochondral lesion of the talus (OLT) is a lesion involving the talar articular cartilage and its subchondral bone. OLT is a known cause of chronic ankle pain after ankle sprains in the active population. The lesion causes deep ankle pain associated with weight-bearing, impaired function, limited range of motion, stiffness, catching, locking, and swelling. ⋯ Postoperative fluoroscopy and computed tomography images showed bone cement filling of the defect. In the present case, arthroscopic and fluoroscopic guidance was used for aspiration of an OLT and for performing percutaneous osteoplasty with hydroxyapatite for one defect; this treatment decreased pain upon weight bearing and enabled a return to work without any restrictions one week after the procedure. The purpose of this report was to highlight the presence of OLT in chronic ankle pain and to review its management strategies.

Millions of interventional pain procedures are performed each year in the United States. Interventional pain physicians commonly administer radiocontrast media (RCM) under fluoroscopy for these procedures. However, RCM can cause various types of hypersensitivity or allergic type reactions, in an acute or delayed fashion. Furthermore, some patients report a prior history of hypersensitivity reactions to RCM when presenting to the interventional pain clinic. Both scenarios present challenges to the interventional pain physician. ⋯ Although the mechanisms of various RCM allergic-type reactions are not entirely understood, the interventional pain physician should have a basic understanding of patient risk factors, prevention, diagnosis, and treatment of these reactions. The current review allowed for prevention and treatment strategies for managing patients with RCM hypersensitivity reactions.
