Pituitary apoplexy occurs as a very rare complication following pituitary function tests. Signs and symptoms are due to the rapid expansion of an infarcted and/or haemorrhagic pituitary adenoma. We report a case of macroadenoma, in which pituitary apoplexy developed 30 minutes after administration of thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH) injections. Magne...

BACKGROUND AND PURPOSE Clival invasion, a rare but potentially significant complication of pituitary adenoma, is difficult to detect on MR imaging. Because CT is widely used in adjunct guidance of pituitary surgery and it has recently been suggested that preoperative CT may add useful diagnostic information in addition to pituitary MR imaging, we performed the first large cross-sectional imagin...

BACKGROUND Pituitary carcinomas are rare neuroendocrine tumors affecting the adenohypophysis. The hallmark of these lesions is the demonstration of distant metastatic spread. To date, few well-documented cases have been reported in the literature. CASE PRESENTATION Here, we report the case of a fatal pituitary carcinoma evolving within two years from an adrenocorticotrophic hormone (ACTH)-sec...

INTRODUCTION This report describes the case of a male patient with pituitary macroadenoma treated with the artemisinin analog artemether. PATIENT AND METHODS A 75 year-old male patient presented with vision, hearing, and locomotion-related problems. Artemether was administered orally to the patient over a period of 12 months. RESULTS Although the tumor remained consistent in size, CT scan s...

The authors report a rare case of bilateral Tolosa-Hunt syndrome, which occurred in a 80-year-old female and remitted spontaneously. Inflammatory lesions were found not only in typical locations, i.e. superior orbital fissures and cavernous sinuses, but also in the pituitary; these imitated gland's macroadenoma in imaging studies.
