Two patients with spinal arachnoiditis following subarachnoid haemorrhage are described. A complete spinal block was seen at the mid thoracic level with characteristics of spinal arachnoiditis. Only one patient had severe symptoms. Both patients were treated conservatively. Signs and symptoms diminished in time. A review of the literature is given and the aetiology is discussed.

We studied a child with a rapidly progressive neurologic disorder, with psychomotor retardation, hypotonia, seizures, and respiratory disturbances. Laboratory studied showed elevated levels of lactate and pyruvate in cerebrospinal fluid (CSF), without notable elevated levels in serum. In liver, muscle, leukocytes, and cultured fibroblasts we found no abnormality in pyruvate oxidation; biochemical studies of a brain biopsy showed an isolated deficiency of pyruvate dehydrogenase complex in brain tissue with the morphologic picture of progressive poliodystrophy with hypomyelination.

The interhemispheric subdural hematoma is a relatively uncommon type of subdural hematoma, especially seen in patients with blood clotting disturbances. When its mass becomes sufficiently large, specific neurological abnormalities such as hemiparesis and signs of the falx syndrome are seen. Treatment can consist of conservative observation or craniotomy and is dictated by the clinical course. Conservative management is the treatment of choice for patients without disturbances of consciousness and for patients with stable clinical conditions. Surgical treatment is necessary in patients with progressive deterioration. Three case reports are presented, as well as a review of 64 cases described in the literature. The salient aspects of this clinical entity are discussed.
