    Ectopic Prolactinoma Presenting as Bacterial Meningitis: A Diagnostic Conundrum.
    World Neurosurg 2018 Jan 26. Epub 2018 Jan 26.
    Introduction: Prolactinomas may rarely present with meningitis and cerebrospinal fluid (CSF) rhinorrhea secondary to erosion of the wall of the sella turcica. It is even more un-common for this abnormal communication to be caused by an ectopic prolactinoma arising from the sphenoid sinus and eroding into the sella. This atypical growth pattern makes diagnosis very difficult, as there may be no displacement of the normal pituitary gland. Read More

    Cabergoline-induced fibrosis of prolactinomas: a neurosurgical perspective.
    BMJ Case Rep 2017 Nov 3;2017. Epub 2017 Nov 3.
    Division of Neurosurgery, National University Hospital (NUH), Singapore.
    Presently, the standard of care for prolactinomas, a type of pituitary adenoma, is dopaminergic agents such as bromocriptine and cabergoline. However, dopaminergic agents may induce fibrosis of cardiac valves leading to valvular insufficiency, necessitating surgical treatment of prolactinoma. Fibrosis of prolactinoma can be induced by prolonged medical treatment with bromocriptine, and this usually occurs after years of treatment. Read More

    Sex differences in the pituitary TGFβ1 system: The role of TGFβ1 in prolactinoma development.
    Front Neuroendocrinol 2017 Oct 24. Epub 2017 Oct 24.
    Instituto de Biología y Medicina Experimental, Consejo Nacional de Investigaciones Científicas y Técnicas, V. Obligado 2490, 1428 Buenos Aires, Argentina. Electronic address:
    Prolactinomas are the most frequent functioning pituitary adenomas, and sex differences in tumor size, behavior and incidence have been described. These differences have been associated with earlier diagnosis in woman, as well as with serum estradiol levels. Experimental models of prolactinomas in rodents also show a higher incidence in females, and recent findings suggest that gender differences in the transforming growth factor beta 1 (TGFβ1) system might be involved in the sex-specific development of prolactinomas in these models.
