Hypercalcaemia associated with cerebral vasospasm causing infarction.
Central nervous system disorders are not uncommon in patients with hyperparathyroidism and hypercalcaemia. Usually these consist of neuropsychiatric disturbances but acute encephalopathies and seizures may occur. A rare manifestation is cerebral infarction. A patient is presented with neuroradiological evidence of infarction caused by cerebral arterial spasm which appears related to hypercalcaemia due to hypervitaminosis D. Arterial spasm is suggested as a possible aetiological factor in focal neurological lesions associated with hypercalcaemia.
