After subarachnoid hemorrhage (SAH) cerebral metabolism is significantly impaired. Hyperglycolysis describes the reduction of oxidative metabolism followed by a relative increase of anaerobic glycolysis to maintain energy supply. This phenomenon is known in head injury but has not as yet been shown after SAH. ⋯ In patients who died after SAH almost 50% of studies showed hyperglycolysis, whereas patients who survived without neurological deficit had no hyperglycolytic events. Relative hyperglycolysis is a common event after SAH. It may be associated with relative hyperemia but most importantly with outcome.

This study reports two patients with ligamentum flavum hematoma, of which only seven cases have been reported in the literature. Two elderly male patients (74 and 80 years) presented with a history of chronic lumbar strain and effort. They had low back pain radiating to both legs. ⋯ The most common cystic lesion in the lumbar spine is synovial cyst associated with the facet joints, but ligamentum flavum hematoma should be included in the differential diagnosis. The clinical, radiological and surgical features are described. Surgery should be the treatment of choice to resolve symptoms in ligamentum flavum hematoma.
