Tenosynovial giant cell tumours (TGT) are benign tumours that arise in the synovial lining of joints, tendon sheaths and bursae. Tumours arising from the vertebral column are extremely rare, with few cases reported. ⋯ To our knowledge and after a review of the literature, this is the first patient with a TGT involving the brachial plexus. The clinical, radiological and histological features of this tumour are described together with a brief discussion of management options.

Adiponectin affects nitric oxide production, and low plasma adiponectin levels are associated with impaired endothelium-dependent vasorelaxation. However, adiponectin pathophysiology in the acute phase after stroke, especially subarachnoid hemorrhage, is not well understood. The present study evaluated the changes in plasma adiponectin concentrations in patients with subarachnoid hemorrhage and investigated the relationship between plasma adiponectin and delayed cerebral ischemia. ⋯ The plasma adiponectin concentrations were significantly lower in patients on days 3 and 7 compared with controls. Plasma adiponectin concentrations in patients with delayed cerebral ischemia were significantly lower than in those without delayed cerebral ischemia on days 3, 7, 10, and 14. The present results indicate that low plasma adiponectin concentrations from day 3 to day 14 might be associated with the development of delayed cerebral ischemia.
