Where is the culprit? A case of acromegaly that defied the management algorithm

Abstract

SUMMARYA 30-year-old Filipino man presented with a 11-year history of coarse facial features and progressive enlargement of hands and feet. Initial work-up revealed elevated insulin-like growth factor-1 and nonsuppressible growth hormone level after 75 g glucose challenge test. Initial cranial MRI performed in the year 2010 showed absence of pituitary adenoma. The patient was lost to follow-up. He again consulted in the year 2011 and a repeat cranial MRI and a dedicated pituitary MRI were performed and both did not reveal any pituitary mass. Further investigation included chest and abdominal CT scan, both of which did not show any neoplasm. At present, there has been no practice guideline on the management of acromegalic patients on whom the identifiable source cannot be found. The patient was given the option to undergo surgical exploration of the pituitary gland or medical treatment with somatostatin analogues. He decided to undergo surgery but has not given consent for the procedure.
