Metastatic carcinoid tumour of the CNS from two different primary sites

Two cases of carcinoid tumour affecting the central nervous system through their metastases were treated surgically. The first case was carcinoid tumour of the lung with a single metastases in the right frontal lobe of the brain, while the second developed metastases of the sixth thoracic vertebra from a terminal ileum bowel primary causing spinal cord compression. Neither case developed carcinoid syndrome. The rarity of such metastases affecting the central nervous system is discussed together with a review of the literature.
