Pituitary adenoma (PA), among the most commonly encountered sellar pathologies, accounts for 10% of primary intracranial tumors. The reported incidence of postoperative diabetes insipidus (DI) is highly variable. In this study, we report our experience with DI following endoscopic transsphenoidal surgery (TSS) for PAs, elucidating the risk factors of postoperative DI, the likelihood of long-term DI, and the impact of DI on the length of stay (LOS).

Myasthenia gravis (MG) is an autoimmune disease affecting neuromuscular transmission that manifests with muscle weakness and typically involves the eye muscles, often producing diplopia and ptosis. Recent studies suggest that hyperprolactinaemia may have a role in the development of MG, although its association with prolactinoma is extremely rare. We report the unusual case of a 71-year-old male affected with macroprolactinoma, who presented at our Center 2 weeks after starting cabergoline treatment because of acute onset of headache, diplopia, and ptosis.

The treatment objectives for a patient with Cushing's disease (CD) are remission of hypercortisolism, adequate management of co-morbidities, restoration of the hypothalamic-pituitary-adrenal axis, preservation of fertility and pituitary function, and improvement of visual defects in cases of macroadenomas with suprasellar extension. Transsphenoidal pituitary surgery is the main treatment option for the majority of cases, even in macroadenomas with low probability of remission. In cases of surgical failure, another subsequent pituitary surgery might be indicated in cases with persistent tumor imaging at post surgical magnetic resonance imaging (MRI) and/or pathology analysis of adrenocorticotropic hormone-positive (ACTH+) positive pituitary adenoma in the first procedure.

Cerebrospinal fluid (CSF) rhinorrhea is rarely reported as the first presenting feature of giant invasive macroprolactinomas. Cerebrospinal fluid rhinorrhea is usually reported as a complication of trauma, neurosurgical, and skull-based procedures (such as pituitary surgery or radiations), and less frequently after medical treatment with dopamine agonists (DAs) for macroprolactinomas. This phenomenon results from fistula creation that communicates between the subarachnoid space and the nasal cavity. Read More

Purpose: Despite the established role of O6-methyl-guanine-DNA methyltransferase (MGMT) as a marker for temozolomide response, consensus of the most reliable method to assess MGMT expression in pituitary adenomas is still missing. Currently, immunohistochemistry (IHC) assessment of formaldehyde fixed tissue samples is most widely used in a semiquantitative description. As formaldehyde fails to completely preserve nucleic acids, RCL2, an alcohol-based formaldehyde-free fixative, has been proposed as a more reliable alternative in terms of cell stability. Read More

Clinically nonfunctioning pituitary adenomas (NFAs) range from those causing significant hypothalamic/pituitary dysfunction and visual field compromise due to their large size to those being completely asymptomatic. In the absence of hypersecretion, hypopituitarism or visual field defects, patients with NFAs may be followed by periodic surveillance using MRI to detect tumor enlargement. In some cases, endocrine tests are also needed during observation to discover new pituitary dysfunction. Read More
