Granular cell tumour of the neurohypophysis.
Granular cell tumours of the neurohypophysis are very rare. Their aetiology and nature are uncertain. Most investigators consider them to arise from pituicytes or Schwann cells of the posterior lobe of the hypophysis. They are found most commonly in older people. A surgically proven symptomatic case is reported.
