Medically responsive amyloidogenic giant sellar-parasellar prolactinoma

Abstract

Background: Giant prolactinomas are rare; among them, the amyloidogenic variant, prolactinomas with extensive spherical amyloid deposits, are rare, with only 30 cases reported with recommendations of surgical management contrary to the routine prolactinoma’s medical management. Case Description: We report here a case of giant amyloidogenic prolactinoma in a 32-year-old male patient who had a very atypical presentation in terms of clinical, radiological, and pathological features and responded to dopamine agonist therapy like a normal prolactinoma. Conclusion: Amyloidogenic giant prolactinomas are rare. Contrary to usual belief, even they remain medically responsive; however, more literature is required to decide their ideal management.
