Spherical amyloid deposition in a prolactin-producing pituitary adenoma. [JOURNAL ARTICLE]
Neuropathology 2008 May 21.
A 41-year-old man presented with headache, right-sided ophthalmic pain and visual deficit. His neurological examination was normal except for bitemporal hemianopsia and right lower quadranopsia. MRI demonstrated a mass arising from the pituitary gland. Hormonal analysis revealed an elevated prolactin level of 4700 ng/mL (normal 4.04-15.2 ng/mL). MRI revealed hypointense signal on T2-weighted images. Moreover, we also concluded that foci with no intravenous contrast enhancement represent the amyloid deposits. The patient underwent trans-sphenoidal resection of the pituitary adenoma. Histological examination revealed an adenoma with spheroid amyloid deposits adjacent to prolactin-staining adenoma cells. The patient recovered from the surgery without complications.
