- Abstract
Pituitary carcinoma is a rare entity comprising 0.1-0.2% of all pituitary tumors and presents significant diagnostic and therapeutic challenges. Intraspinal drop metastasis in these tumors is even rarer. We report a case of a prolactin secreting pituitary carcinoma with intracranial metastasis and multiple intraspinal drop metastasis. This is the first case where 68Gallium labelled [1,4,7,10 - tetraazacyclododecane - 1,4,7,10 - tetraacetic acid] -1- NaI3 - octreotide (68Ga-DOTANOC) whole-body positron emission tomography-computed tomography (PET-CT) has been used in a case of malignant prolactinoma, in an attempt to ascertain the somatostatin receptor (SSTR) expression on tumor cells. Through this paper, we suggest that SSTR targeted radionuclide therapy could have a potential role in aggressive pituitary tumors and pituitary carcinomas similar to the promising role of lutetium-labelled peptides in inoperable or metastasized gastroentero-pancreatic neuroendocrine tumors (GEP-NETs)., (Copyright © 2024 Copyright: © 2024 Neurology India, Neurological Society of India.)
