Abstract A 44-year-old woman presented with a chiasmal syndrome which on neurosurgical exploration was found to be due to a granular cell myoblastoma of the neurohypophysis. The presenting clinical symptoms in this and previously reported cases do not differentiate this tumor from other causes of chiasmal syndrome. The histologic appearance of these tumors is characteristic and resembles asymptomatic tumor nodules found in 6.5% of autopsies. References 1.
