Pituitary adenoma is a benign neoplasm of pituitary gland. adenoma, particularly macroadenoma,may produce mass effect symptoms by compressing surrounding tissues. Due to function as aneuroendocrine organ, may also cause multiple endocrine disturbances. The authors reportthe case 39-year-old male patient presenting with chronic headache and history seizure. MRI imagingrevealed macroadenoma optic...

CT scans of the type braincase Limaysaurus tessonei (MUCPv-205) allowed first study endocranial cavities (brain and inner ear) for this South American taxon. Comparisons cranial endocast L. with other sauropods indicate that 1) rebbachisaurids are more similar to each than Nigersaurus, 2) certain association traits present in all known rebbachisaurid endocasts, such as lack an enlarged dorsal e...

Management of pituitary conditions can be problematic with many patients experiencing long-term psychological and social difficulties that impact on their quality life. This study aimed to identify psychosocial symptoms associated lead poor life differences in symptomatology between patient groups. A survey using measures was sent 2000 members the Pituitary Foundation January 2016. The complete...

The purpose of this study was to determine whether the MR findings of idiopathic pituitary dwarfism correlated with a clinical history of perinatal abnormalities and abnormal levels of pituitary hormones. MR examinations of 18 patients with pituitary dwarfism were performed; these patients were divided into two groups: those with ectopic posterior lobes (group 1) and those with normal posterior...

UNLABELLED Pituitary abscess is a relatively uncommon cause of pituitary hormone deficiencies and/or a suprasellar mass. Risk factors for pituitary abscess include prior surgery, irradiation and/or pathology of the suprasellar region as well as underlying infections. We present the case of a 22-year-old female presenting with a spontaneous pituitary abscess in the absence of risk factors descri...

UNLABELLED We have developed a new imaging method to evaluate the blood perfusion and ammonia metabolism of the pituitary gland, and we preliminarily assessed its role in the diagnosis of hypopituitarism. METHODS Six female healthy volunteers (age range, 20-46 y) and 6 female patients (age range, 23-42 y) were enrolled in this study. Dynamic (13)N-NH(3) PET was performed. Time-activity curves...

We recently reported that TRH-deficient mice showed characteristic tertiary hypothyroidism. In the present study, we investigated how this tertiary hypothyroidism occurred particularly in pre- and postnatal stages. Immunohistochemical analysis revealed a number of TSH-immunopositive cells in the TRH-/- pituitary on embryonic day 17.5 and at birth. The mutant pituitary at birth in pups born from...

IMPORTANCE Extracranial pituitary ectopia is an uncommon finding characterized by all or a portion of the pituitary gland situated in an aberrant location. Often these lesions come to clinical attention only once they begin to function abnormally or increase in size significantly. OBSERVATIONS We describe an incidentally noted, asymptomatic pedunculated nasopharyngeal lesion in a 13-month-old...
