Few studies have used hybrid single-photon emission computed tomography (SPECT)/computed tomography (CT) scan to identify degenerative facet disease. We aimed to determine the incidence of hypermetabolic facets on SPECT/CT imaging in patients with axial neck or back pain to elucidate the value of SPECT/CT scan in identifying pain generators. ⋯ Nearly half of all patients with axial neck or back pain demonstrated ZJH on SPECT/CT imaging, supporting ZJH sites as potential pain generators and targets for treatment. Our results support the role for SPECT/CT imaging in the workup of patients with axial neck or back pain, which may reduce invasive diagnostic procedures and aid in treatment planning.

Meningioangiomatosis is an extremely rare meningovascular disease of the central nervous system that is characterized by the proliferation of leptomeninges, cortical vessels, and perivascular spindled cells. Although it is a benign, neoplastic disorder that carries a good prognosis after surgical excision, initial diagnosis may be challenging as radiologic findings are often variable and nonspecific. ⋯ In view of the unexpected diagnosis and infrequency of this condition, the case is discussed in collaboration with current literature and management strategies.

Rheumatoid meningitis is a rare manifestation of autoimmune rheumatoid arthritis. ⋯ In the present report, we have discussed the diagnostic and therapeutic approach to rheumatoid meningitis.

Few studies have examined the usefulness of intraoperative magnetic resonance spectroscopy (iMRS) for identifying abnormal signals at the resection margin during glioma surgery. The aim of this study was to assess the value of iMRS for detecting proliferative remnants of glioma at the resection margin. ⋯ This study provides evidence that 3-T iMRS can detect proliferative remnants of glioma at the resection margin using the Cho level and Cho/NAA ratio, suggesting that intraoperative magnetic resonance imaging-assisted surgery with iMRS would be practicable in glioma.

The ARUBA trial (A Randomized Trial of Unruptured Brain Arteriovenous Malformations) was the first randomized control trial to investigate unruptured cerebral arteriovenous malformation (cAVM) treatments and concluded that medical management was superior to interventional therapy for the treatment of unruptured cAVMs. This conclusion generated considerable controversy and was followed by rebuttals and meta-analyses of the ARUBA methodology and results. We sought to determine whether the ARUBA results altered treatment trends of cAVMs within the United States. ⋯ Our findings suggest that the ARUBA trial has influenced unruptured cAVM treatment patterns within the United States. Although the overall treatment rate has decreased, unruptured cAVMs, when treated post-ARUBA, are most commonly approached with surgical excision alone.
