Sa. Hedderwick et al., SURGICAL CURE OF HYPERTENSION IN A PATIENT WITH BRAIN-STEM CAPILLARY HEMANGIOBLASTOMA CONTAINING NEUROPEPTIDE-Y, Postgraduate medical journal, 71(836), 1995, pp. 371-372
We describe a 29-year-old woman with persistent arterial hypertension
which resolved following complete excision of a capillary haemangiobla
stoma from within the spinal cord at the cervicomedullary junction. Im
munohistochemical staining was positive for neuropeptide Y in capillar
y walls and nerves in the tumour. This raises the possibility of an as
sociation between neuropeptide Y and the central control of blood pres
sure in man.
