We report a unique case and presentation of a 77-year-old man with atrial fibrillation who presented with complex imaging features, including bifrontal cerebral hematomas that progressed to multifocal macro- and microhemorrhages, vasogenic edema, and cortical/meningeal enhancement. Cerebrospinal fluid analysis was only remarkable for a protein elevation of 65 mg/dL. Leptomeningeal vessel biopsy failed to demonstrate evidence of amyloid angiopathy but did show concentric obstructive intimal fibroplasia, suggestive of chronic venous congestion. Conventional cerebral angiography showed a Cognard type IV dural arteriovenous fistulae fed by bilateral ethmoidal arteries draining directly into ectatic cortical veins. A chronic occlusion of the anterior third of the superior sagittal sinus was also noted. The fistula was successfully surgically obliterated via an uncomplicated left frontal craniotomy approach. After rehabilitation therapy, he was discharged home with a modified Rankin Scale score of 3. Because effective treatment exists, this case underscores the importance of identifying this rare etiology of intracerebral hemorrhage and pursuing adequate workup.

IN BRIEF Diabetes has been associated with the incidence of back pain. However, the relationship between markers of diabetes progression and back pain has not been studied. The objective of this study was to correlate clinical and laboratory measures of diabetes disease severity to the presence of back pain to provide insight into the relationship between these conditions. Findings showed that markers of diabetes disease progression were associated with the presence of back pain, suggesting that uncontrolled diabetes may contribute to the development of chronic back pain.
